+                  GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+
+    lib-sieve: sieve-result - Fix panic occurring upon temp fail after committed
+    keep-equivalent action.
+
+    The determination of whether a keep-equivalent action was already executed
+    is performed in sieve_result_implicit_keep_execute(), which can also be
+    called from sieve_result_implicit_keep_finalize(). But there, the
+    keep-equivalent status was checked before any call to
+    sieve_result_implicit_keep_execute(), which would thus yield the wrong
+    result.
+
+    This change also makes the associated debug message more specific (otherwise
+    two identical debug messages are logged) and an assert is added that makes
+    sure the keep-equivalent action is actually finalized when the implicit keep
+    was supposed to be finalized.
+
+    Panic was:
+
+    Panic: file sieve-result.c: line 1706 (sieve_result_implicit_keep_finalize):

+
+    lib-sieve: plugins: duplicate: Only save duplicate entry when the last
+    script executed successfully.
+
+    This prevents prematurely marking duplicates when errors occur during result 
+    execution. Before, the pending duplicate database changes were committed
+    after each script executed in the sequence. If a later script failed,
+    duplicate tests would mark duplicate messages prematurely.
+
+    Disadvantage is that actions in earlier scripts that are shielded by a
+    duplicate test can be executed twice erroneously when errors occurred in
+    later scripts in the previous delivery. Still, unexpected duplicate action
+    execution is better than losing mail due to erroneous duplicate detections.
+
+    Fixing this properly requires extensively restructuring result execution.

+    testsuite: Drop needless result reference in testsuite_run().
+
+    This holds a reference to the initial result, causing it to linger after

+    preventing it from being cleared. This in turn, can keep references to
+    modified message versions that cause the main message object to remain
+    referenced. This causes a panic in specific cases upon test_result_reset:

+
+    lib-sieve: imap4flags extension: Fix binary corruption occurring when
+    setflag/addflag/removeflag flag-list is a variable.
+
+    The original implementation checked the first operand for being a variable. 
+    Obviously, when the assigned flag string is just a variable, this doesn't
+    work. This causes the flag list to be recognized erroneously as a variable
+    flags string. Fixed the problem by explicitly emitting an omitted operand
+    when there is no second argument for a setflag/addflag/removeflag.
+
+    Because the new byte code format is incompatible, the extension version is 
+    bumped to 1.

+
+    This adds a new "sieve_discard" setting that points to the location of the

+    that the message will be discarded without being delivered anywhere, the
+    "discard script" is executed. The discard script can prevent dropping the
+    message, by executing alternative actions. If the discard script does

+
+    Changed behavior of redirect in case of a duplicate message delivery or a
+    mail loop. If a duplicate is detected the implicit keep is canceled, as
+    though the redirect was successful. This prevents getting local deliveries.
+    The original SMTP recipient is used when it is available to augment the
+    entry in the LDA duplicate database. This way, duplicates are only detected
+    when (initially) addressed to the same recipient. The main goal of the
+    duplicate detection is mail loop prevention, but this also has the effect
+    that mere duplicate deliveries are handled specially whithout a good reason.
+    We should fix this in a future version.

+
+    Fixed interaction of Sieve include extension with ManageSieve. Upon upload,
+    the include extension is more lenient towards circular includes and missing
+    scripts as required by RFC. The script is now also verified upon SETACTIVE
+    when it was not active before. However, this new SETACTIVE behavior is not
+    optimal for the situation where the active script was updated with PUTSCRIPT
+    and contains an nonexistent include (ignored during upload). This can still
+    cause runtime errors, since an already active script is not verified again
+    during SETACTIVE.

+
+    Improved runtime error handing.
+
+    - Changed operand read functions to prove exec status return codes in stead
+    of boolean.
+    - Restructured optional-operand, stringlist and string-match APIs to provide
+    execution status (error code) upon failure.
+    - Corruption errors are only produced when the binary is actually corrupt.
+    Normal failures should never cause a recompile attempt anymore.
+    - Simplified optional-operand API.
+    - Cleaned up test command implementations that use the string-match API.

+    Imap4flags: fixed bug in the handling of the internal variable.
+
+    Previously the final value of internal variable was for every store action
+    that didn't specify a :flags argument explicitly. This results in out-of
+    order assignment/removal of flags, e.g. also the flags assigned keep actions
+    that were executed before the addflag/setflag command were modified.

+Compiling
+=========
+
+If you downloaded the sources using Mercurial, you will need to execute
+./autogen.sh first to build the automake structure in your source tree. This
+process requires autotools and libtool to be installed.
+
+If you installed Dovecot from sources, Pigeonhole's configure script should be
+able to find the installed dovecot-config automatically:
+
+./configure
+make
+sudo make install
+
+If your system uses a $prefix different than the default /usr/local, the
+configure script can still find the installed dovecot-config automatically when
+supplied with the proper --prefix argument:
+
+./configure --prefix=/usr
+make
+sudo make install
+
+If this doesn't work, you can use --with-dovecot=<path> configure option, where
+the path points to a directory containing dovecot-config file. This can point to
+an installed file:
+
+./configure --with-dovecot=/usr/local/lib/dovecot
+make
+sudo make install
+
+or to a Dovecot source directory that is already compiled:
+
+./configure --with-dovecot=../dovecot-2.1.0
+make
+sudo make install
+
+The following additional parameters may be of interest for the configuration of
+the Pigeonhole build:
+
+ --with-managesieve=yes
+   Controls whether Pigeonhole ManageSieve is compiled and installed, which is
+   the default.
+
+ --with-unfinished-features=no
+   Controls whether unfinished features and extensions are built. Enabling this
+   will enable the compilation of code that is considered unfinished and highly
+   experimental and may therefore introduce bugs and unexpected behavior.
+   In fact, it may not compile at all. Enable this only when you are eager to
+   test some of the new development functionality.
+
+ --with-ldap=no
+   Controls wether Sieve LDAP support is built. This allows retrieving Sieve
+   scripts from an LDAP database. When set to `yes', support is built in. When
+   set to `plugin', LDAP support is compiled into a Sieve plugin called
+   `sieve_storage_ldap'.
+
+Configuration
+=============
+
+The Pigeonhole package provides the following items:
+
+  - The Sieve interpreter plugin for Dovecot's Local Delivery Agent (LDA): This
+    facilitates the actual Sieve filtering upon delivery.
+
+  - The ManageSieve Service: This implements the ManageSieve protocol through
+    which users can remotely manage Sieve scripts on the server.
+
+The functionality of these items is described in more detail in the README file.
+In this file and in this section their configuration is described. Example
+configuration files are provided in the doc/example-config directory of this
+package.
+
+Sieve Interpreter - Script Locations
+------------------------------------
+
+The Sieve interpreter can retrieve Sieve scripts from several types of
+locations. The default `file' location type is a local filesystem path pointing
+to a Sieve script file or a directory containing multiple Sieve script files.
+More complex setups can use other location types such as `ldap' or `dict' to
+fetch Sieve scripts from remote databases.
+
+All settings that specify the location of one ore more Sieve scripts accept the
+following syntax:
+
+location = [<type>:]path[;<option>[=<value>][;...]]
+
+The following script location types are implemented by default:
+
+  file  - The location path is a file system path pointing to the script file
+          or a directory containing script files with names structured as
+          `<script-name>.sieve'. Read doc/locations/file.txt for more
+          information and examples.
+
+  dict  - The location path is a Dovecot dict uri. Read doc/locations/dict.txt
+          for more information and examples.
+
+  ldap  - LDAP database lookup. The location path is a configuration file with
+          LDAP options. Read doc/locations/ldap.txt for more information
+          and examples.
+
+If the type prefix is omitted, the script location type is 'file' and the 
+location is interpreted as a local filesystem path pointing to a Sieve script
+file or directory.
+
+The following options are defined for all location types:
+
+  name=<script-name>
+    Set the name of the Sieve script that this location points to. If the name
+    of the Sieve script is not contained in the location path and the
+    location of a single script is specified, this option is required
+    (e.g. for dict locations that must point to a particular script).
+    If the name of the script is contained in the location path, the value of
+    the name option overrides the name retrieved from the location. If the Sieve
+    interpreter explicitly queries for a specific name (e.g. to let the Sieve
+    "include" extension retrieve a script from the sieve_global= location),
+    this option has no effect.
+
+  bindir=<dirpath>
+    Points to the directory where the compiled binaries for this script location
+    are stored. This directory is created automatically if possible. If this
+    option is omitted, the behavior depends on the location type. For `file'
+    type locations, the binary is then stored in the same directory as where the
+    script file was found if possible. For `dict' type locations, the binary is
+    not stored at all in that case. Don't specify the same directory for
+    different script locations, as this will result in undefined behavior.
+    Multiple mail users can share a single script directory if the script
+    location is the same and all users share the same system credentials (uid,
+    gid).
+
+Sieve Interpreter - Basic Configuration
+---------------------------------------
+
+To use Sieve, you will first need to make sure you are using Dovecot LDA
+or Dovecot LMTP for delivering incoming mail to users' mailboxes. Then, you need
+to enable the Sieve interpreter plugin for LDA/LMTP in your dovecot.conf:
+
+protocol lda {
+..
+  mail_plugins = sieve # ... other plugins like quota
+}
+
+protocol lmtp {
+..
+  mail_plugins = sieve # ... other plugins like quota
+}
+
+The Sieve interpreter recognizes the following configuration options in the
+plugin section of the config file (default values are shown if applicable):
+
+ sieve = file:~/sieve;active=~/.dovecot.sieve
+   The location of the user's main Sieve script or script storage. The LDA
+   Sieve plugin uses this to find the active script for Sieve filtering at
+   delivery. The "include" extension uses this location for retrieving
+   :personal" scripts.
+
+   This location is also where the ManageSieve service will store the user's
+   scripts, if supported by the location type. For the 'file' location type, the
+   location will then be the path to the storage directory for all the user's
+   personal Sieve scripts. ManageSieve maintains a symbolic link pointing to
+   the currently active script (the script executed at delivery). The location
+   of this symbolic link can be configured using the `;active=<path>' option.
+
+ sieve_default =
+   The location of the default personal sieve script file, which gets executed
+   ONLY if user's private Sieve script does not exist, e.g.
+   /var/lib/dovecot/default.sieve. This is usually a global script, so be sure
+   to pre-compile this script manually using the sievec command line tool, as
+   explained in the README file. This setting used to be called
+   `sieve_global_path', but that name is now deprecated.
+
+ sieve_default_name = 
+   The name by which the default Sieve script is visible to ManageSieve
+   clients. Normally, it is not visible at all. See "Visible Default Script"
+   section below for more information.
+
+ sieve_global =
+   Location for :global include scripts for the Sieve include extension. This
+   setting used to be called `sieve_global_dir', but that name is now
+   deprecated.
+
+ sieve_discard =
+   The location of a Sieve script that is run for any message that is about to
+   be discarded; i.e., it is not delivered anywhere by the normal Sieve
+   execution. This only happens when the "implicit keep" is canceled, by e.g.
+   the "discard" action, and no actions that deliver the message are executed.
+   This "discard script" can prevent discarding the message, by executing
+   alternative actions. If the discard script does nothing, the message is still
+   discarded as it would be when no discard script is configured.
+
+ sieve_extensions =
+   Which Sieve language extensions are available to users. By default, all
+   supported extensions are available, except for deprecated extensions or those
+   that are still under development. Some system administrators may want to
+   disable certain Sieve extensions or enable those that are not available by
+   default. This setting can use '+' and '-' to specify differences relative to
+   the default. For example `sieve_extensions = +imapflags' will enable the
+   deprecated imapflags extension in addition to all extensions were already
+   enabled by default.
+
+ sieve_global_extensions =
+   Which Sieve language extensions are ONLY avalable in global scripts. This can
+   be used to restrict the use of certain Sieve extensions to administrator
+   control, for instance when these extensions can cause security concerns. This
+   setting has higher precedence than the `sieve_extensions' setting (above),
+   meaning that the extensions enabled with this setting are never available to
+   the user's personal script no matter what is specified for the
+   `sieve_extensions' setting. The syntax of this setting is similar to
+   the `sieve_extensions' setting, with the difference that extensions are
+   enabled or disabled for exclusive use in global scripts. Currently, no
+   extensions are marked as such by default.
+
+ sieve_implicit_extensions =
+   Which Sieve language extensions are implicitly available to users. The
+   extensions listed in this setting do not need to be enabled explicitly using
+   the Sieve "require" command. This behavior directly violates the Sieve
+   standard, but can be necessary for compatibility with some existing
+   implementations of Sieve (notably jSieve). Do not use this setting unless you
+   really need to! The syntax and semantics of this setting are otherwise
+   identical to the `sieve_extensions' setting
+
+ sieve_plugins =
+   The Pigeonhole Sieve interpreter can have plugins of its own. Using this
+   setting, the used plugins can be specified. Check the Dovecot wiki
+   (wiki2.dovecot.org) or the pigeonhole website (http://pigeonhole.dovecot.org)
+   for available plugins. The `sieve_extprograms' plugin is included in this
+   release. LDAP support may also be compiled as a plugin called
+   `sieve_storage_ldap'.
+
+ sieve_user_email =
+   The primary e-mail address for the user. This is used as a default when no
+   other appropriate address is available for sending messages. If this setting
+   is not configured, either the postmaster or null "<>" address is used as a
+   sender, depending on the action involved. This setting is important when
+   there is no message envelope to extract addresses from, such as when the
+   script is executed in IMAP.
+
+ sieve_user_log =
+   The path to the file where the user log file is written. If not configured, a
+   default location is used. If the main user's personal Sieve (as configured
+   with sieve=) is a file, the logfile is set to <filename>.log by default. If
+   it is not a file, the default user log file is ~/.dovecot.sieve.log.
+
+ recipient_delimiter = +
+   The separator that is expected between the :user and :detail address parts
+   introduced by the subaddress extension. This may also be a sequence of
+   characters (e.g. '--'). The current implementation looks for the separator
+   from the left of the localpart and uses the first one encountered. The :user
+   part is left of the separator and the :detail part is right. This setting is
+   also used by Dovecot's LMTP service.
+
+ sieve_redirect_envelope_from = sender
+   Specifies what envelope sender address is used for redirected messages.
+   Normally, the Sieve "redirect" command copies the sender address for the
+   redirected message from the  processed message. So, the redirected message
+   appears to originate from the original sender. The following values are
+   supported for this setting:
+   
+     "sender"         - The sender address is used (default).
+     "recipient"      - The final recipient address is used.
+     "orig_recipient" - The original recipient is used.
+     "user_email"     - The user's primary address is used. This is
+                        configured with the "sieve_user_email" setting. If
+                        that setting is unconfigured, "user_mail" is equal to
+                        "sender" (the default).
+     "postmaster"     - The postmaster_address configured for the LDA.
+     "<user@domain>"  - Redirected messages are always sent from user@domain.
+                        The angle brackets are mandatory. The null "<>" address
+                        is also supported.
+
+   When the envelope sender of the processed message is the null address "<>",
+   the envelope sender of the redirected message is also always "<>",
+   irrespective of what is configured for this setting. 
+
+ sieve_redirect_duplicate_period = 12h
+   In an effort to halt potential mail loops, the Sieve redirect action records
+   identifying information for messages it has forwarded. If a duplicate message
+   is seen, it is not redirected and the message is discarded; i.e., the
+   implicit keep is canceled. This setting configures the period during which
+   the identifying information is recorded. If an account forwards many
+   messages, it may be necessary to lower this setting to prevent the
+   ~/.dovecot.lda-dupes database file (in which these are recorded) from growing
+   to an impractical size.
+
+For example:
+
+plugin {
+...
+  # The include extension fetches the :personal scripts from this
+  # directory. When ManageSieve is used, this is also where scripts
+  # are uploaded.
+  sieve = file:~/sieve
+
+  # If the user has no personal active script (i.e. if the location
+  # indicated in sieve= settings does have and active script or does not exist),
+  # use this one:
+  sieve_default = /var/lib/dovecot/sieve/default.sieve
+
+  # The include extension fetches the :global scripts from this
+  # directory.
+  sieve_global = /var/lib/dovecot/sieve/global/
+}
+
+Sieve Interpreter - Configurable Limits
+---------------------------------------
+
+The settings that specify a period are specified in s(econds), unless followed
+by a d(ay), h(our), or m(inute) specifier character.
+
+ sieve_max_script_size = 1M
+   The maximum size of a Sieve script. The compiler will refuse to compile any
+   script larger than this limit. If set to 0, no limit on the script size is
+   enforced.
+
+ sieve_max_actions = 32
+   The maximum number of actions that can be performed during a single script
+   execution. If set to 0, no limit on the total number of actions is enforced.
+
+ sieve_max_redirects = 4
+   The maximum number of redirect actions that can be performed during a single
+   script execution. If set to 0, no redirect actions are allowed.
+
+ sieve_max_cpu_time = 30s
+   The maximum amount of CPU time that a Sieve script is allowed to use while
+   executing. If the execution exceeds this resource limit, the script ends with
+   an error, causing the implicit "keep" action to be executed. This limit is
+   not only enforced for a single script execution, but also cumulatively for
+   the last executions within a configurable timeout
+   (see sieve_resource_usage_timeout).
+
+ sieve_resource_usage_timeout = 1h
+   To prevent abuse, the Sieve interpreter can record resource usage of a Sieve
+   script execution in the compiled binary if it is significant. Currently, this
+   happens when CPU system + user time exceeds 1.5 seconds for one execution.
+   Such high resource usage is summed over time in the binary and once that
+   cumulative resource usage exceeds the limits (sieve_max_cpu_time), the Sieve
+   script is disabled in the binary for future execution, even if an individual
+   execution exceeded no limits. If the last time high resource usage was
+   recorded is older than sieve_resource_usage_timeout, the resource usage in
+   the binary is reset. This means that the Sieve script is only disabled when
+   the limits are cumulatively exceeded within this timeout. With the default
+   configuration this means that the Sieve script is only disabled when the
+   total CPU time of Sieve executions that lasted more than 1.5 seconds exceeds
+   30 seconds in the last hour. A disabled Sieve script can be reactivated by
+   the user by uploading a new version of the Sieve script after the excessive
+   resource usage times out. An administrator can force reactivation by forcing
+   a script compile (e.g. using the sievec command line tool).
+
+Sieve Interpreter - Per-user Sieve Script Location
+--------------------------------------------------
+
+By default, the Pigeonhole LDA Sieve plugin looks for the user's Sieve script
+file in the user's home directory (~/.dovecot.sieve). This requires that the
+home directory is set for the user.
+
+If you want to store the script elsewhere, you can override the default using
+the sieve= setting, which specifies the location of the user's script file. This
+can be done in two ways:
+
+ 1. Define the sieve setting in the plugin section of dovecot.conf.
+ 2. Return sieve extra field from userdb extra fields.
+
+For example, to use a Sieve script file named <username>.sieve in
+/var/sieve-scripts, use:
+
+plugin {
+...
+
+ sieve = /var/sieve-scripts/%u.sieve
+}
+
+You may use templates like %u, as shown in the example. Refer to
+http://wiki.dovecot.org/Variables for more information.
+
+A relative path (or just a filename) will be interpreted to point under the
+user's home directory.
+
+Sieve Interpreter - Executing Multiple Scripts Sequentially
+-----------------------------------------------------------
+
+Pigeonhole's Sieve interpreter allows executing multiple Sieve scripts
+sequentially. The extra scripts can be executed before and after the user's
+private script. For example, this allows executing global Sieve policies before
+the user's script. The following settings in the plugin section of the Dovecot
+config file control the execution sequence:
+
+ sieve_before =
+ sieve_before2 =
+ sieve_before3 = (etc..)
+   Location Sieve of scripts that need to be executed before the user's personal
+   script. If a 'file' location path points to a directory, all the Sieve
+   scripts contained therein (with the proper `.sieve' extension) are executed.
+   The order of execution within that directory is determined by the file names,
+   using a normal 8bit per-character comparison.
+
+   Multiple script locations can be specified by appending an increasing number
+   to the setting name. The Sieve scripts found from these locations are added
+   to the script execution sequence in the specified order. Reading the numbered
+   sieve_before settings stops at the first missing setting, so no numbers may
+   be skipped.
+
+ sieve_after =
+ sieve_after2 =
+ sieve_after3 = (etc..)
+   Identical to sieve_before, but the specified scripts are executed after the
+   user's script (only when keep is still in effect, as explained below).
+
+The script execution ends when the currently executing script in the sequence
+does not yield a "keep" result: when the script terminates, the next script is
+only executed if an implicit or explicit "keep" is in effect. Thus, to end all
+script execution, a script must not execute keep and it must cancel the implicit
+keep, e.g. by executing "discard; stop;". This means that the command "keep;"
+has different semantics when used in a sequence of scripts. For normal Sieve
+execution, "keep;" is equivalent to "fileinto "INBOX";", because both cause the
+message to be stored in INBOX. However, in sequential script execution, it only
+controls whether the next script is executed. Storing the message into INBOX
+(the default folder) is not done until the last script in the sequence executes
+(implicit) keep. To force storing the message into INBOX earlier in the
+sequence, the fileinto command can be used (with ":copy" or together with
+"keep;").
+
+Apart from the keep action, all actions triggered in a script in the sequence
+are executed before continuing to the next script. This means that when a script
+in the sequence encounters an error, actions from earlier executed scripts are
+not affected. The sequence is broken however, meaning that the script execution
+of the offending script is aborted and no further scripts are executed. An
+implicit keep is executed instead if necessary, meaning that the interpreter
+makes sure that the message is at least stored in the default folder (INBOX).
+
+Just as for executing a single script the normal way, the Pigeonhole LDA Sieve
+plugin takes care never to duplicate deliveries, forwards or responses. When
+vacation actions are executed multiple times in different scripts, the usual
+error is not triggered: the subsequent duplicate vacation actions are simply
+discarded.
+
+For example:
+
+plugin {
+...
+   # Global scripts executed before the user's personal script.
+   #   E.g. handling messages marked as dangerous
+   sieve_before = /var/lib/dovecot/sieve/discard-virusses.sieve
+
+   # Domain-level scripts retrieved from LDAP
+   sieve_before2 = ldap:/etc/dovecot/sieve-ldap.conf;name=ldap-domain
+
+   # User-specific scripts executed before the user's personal script.
+   #   E.g. a vacation script managed through a non-ManageSieve GUI.
+   sieve_before3 = /var/vmail/%d/%n/sieve-before
+
+   # User-specific scripts executed after the user's personal script.
+   # (if keep is still in effect)
+   #   E.g. user-specific default mail filing rules
+   sieve_after = /var/vmail/%d/%n/sieve-after
+
+   # Global scripts executed after the user's personal script
+   # (if keep is still in effect)
+   #   E.g. default mail filing rules.
+   sieve_after2 = /var/lib/dovecot/sieve/after.d/
+}
+
+IMPORTANT: The scripts specified by sieve_before and sieve_after are often
+located in global locations to which the Sieve interpreter has no write access
+to store the compiled binaries. In that case, be sure to manually pre-compile
+those scripts using the sievec tool, as explained in the README file.
+
+Sieve Interpreter - Visible Default Script
+------------------------------------------
+
+The `sieve_default=' setting specifies the location of a default script that
+is executed when the user has no active personal script. Normally, this
+default script is invisible to the user; i.e., it is not listed in ManageSieve.
+To give the user the ability to see and read the default script, it is possible
+to make it visible under a specific configurable name using the
+`sieve_default_name' setting.
+
+ManageSieve will magically list the default script under that name, even though
+it does not actually exist in the user's normal script storage location. This
+way, the ManageSieve client can see that it exists and it can retrieve its
+contents. If no normal script is active, the default is always listed as active.
+The user can replace the default with a custom script, by uploading it under the
+default script's name. If that custom script is ever deleted, the default script
+will reappear from the shadows implicitly.
+
+This way, ManageSieve clients will not need any special handling for this
+feature. If the name of the default script is equal to the name the client uses
+for the main script, it will initially see and read the default script when the
+user account is freshly created. The user can edit the script, and when the
+edited script is saved through the ManageSieve client, it will will override the
+default script. If the user ever wants to revert to the default, the user only
+needs to delete the edited script and the default will reappear.
+
+The name by which the default script will be known is configured using the
+`sieve_default_name' setting. Of course, the `sieve_default' setting needs to
+point to a valid script location as well for this to work. If the default script
+does not exist at the indicated location, it is not shown.
+
+For example:
+
+plugin {
+...
+  sieve = file:~/sieve;active=~/.dovecot.sieve
+
+  sieve_default = /var/lib/dovecot/sieve/default.sieve
+	sieve_default_name = roundcube
+}
+
+Sieve Interpreter - Extension Configuration
+-------------------------------------------
+
+- Editheader extension:
+
+  The editheader extension [RFC5293] enables sieve scripts to interact with
+  other components that consume or produce header fields by allowing the script
+  to delete and add header fields.
+
+  The editheader extension requires explicit configuration and is not enabled
+  for use by default. Refer to doc/extensions/editheader.txt for configuration
+  information.
+
+- Vacation extension:
+
+  The Sieve vacation extension [RFC5230] defines a mechanism to generate
+  automatic replies to incoming email messages.
+
+  The vacation extension is available by default, but it has its own specific
+  configuration options. Refer to doc/extensions/vacation.txt for settings
+  specific to the vacation extension.
+
+- Variables extension:
+
+  The Sieve variables extension [RFC5229] adds the concept of variables to the
+  Sieve language.
+
+  The variables extension is available by default, but it has its own specific
+  configuration options. Refer to doc/extensions/variables.txt for settings
+  specific to the variables extension.
+
+- Include extension:
+
+  The Sieve include extension (draft) permits users to include one Sieve script
+  into another.
+
+  The include extension is available by default, but it has its own specific
+  configuration options. Refer to doc/extensions/include.txt for settings
+  specific to the include extension.
+
+- Spamtest and virustest extensions:
+
+  Using the spamtest and virustest extensions (RFC 5235), the Sieve language
+  provides a uniform and standardized command interface for evaluating spam and
+  virus tests performed on the message. Users no longer need to know what headers
+  need to be checked and how the scanner's verdict is represented in the header
+  field value. They only need to know how to use the spamtest (spamtestplus) and
+  virustest extensions. This also gives GUI-based Sieve editors the means to
+  provide a portable and easy to install interface for spam and virus filter
+  configuration.
+
+  The spamtest, spamtestplus and virustest extensions require explicit
+  configuration and are not enabled for use by default. Refer to
+  doc/extensions/spamtest-virustest.txt for configuration information.
+
+- Duplicate extension:
+
+  The duplicate extension augments the Sieve filtering implementation with a
+  test that facilitates detecting and handling duplicate message deliveries,
+  e.g. as caused by mailinglists when people reply both to the mailinglist and
+  the user directly.
+
+  Refer to doc/extensions/vnd.dovecot.duplicate.txt for configuration
+  information.
+
+- Dovecot environment extension:
+
+  The vnd.dovecot.environment extension builds on the standard environment
+  extension. It adds a few extra environment items that are useful for Sieve
+  scripts used by Dovecot.
+
+  Refer to doc/extensions/vnd.dovecot.environment.txt for more information.
+
+- Extprograms plugin;
+    vnd.dovovecot.pipe, vnd.dovecot.filter, vnd.dovecot.execute extensions:
+
+  The "sieve_extprograms" plugin provides extensions to the Sieve filtering
+  language adding new action commands for invoking a predefined set of external
+  programs. Messages can be piped to or filtered through those programs	and
+  string data can be input to and retrieved from those programs.
+
+  This plugin and the extensions it provides require explicit configuration and
+  are not enabled for use by default. Refer to doc/plugins/sieve_extprograms.txt
+  for more information.
+
+- Imapsieve plugins
+
+  The "sieve_imapsieve" Sieve plugin and the "imap_sieve" IMAP plugin add Sieve
+  support to IMAP.
+
+  Refer to doc/plugins/imapsieve.txt for more information.
+
+- IMAP Filter Sieve plugin
+
+  The "imap_filter_sieve" plugin adds the ability to manually invoke Sieve
+  filtering in IMAP.
+
+  Refer to doc/plugins/imap_filter_sieve.txt for more information.
+
+Sieve Interpreter - Trace Debugging
+-----------------------------------
+
+Trace debugging provides detailed insight in the operations performed by
+the Sieve script. Messages about what the Sieve script is doing are written
+to the specified directory.
+
+WARNING: On a busy server, this functionality can quickly fill up the trace
+directory with a lot of trace files. Enable this only temporarily and as
+selective as possible.
+
+The following settings apply to both the LDA Sieve plugin and the IMAPSIEVE
+plugin:
+
+ sieve_trace_dir =  
+  The directory where trace files are written. Trace debugging is disabled if
+  this setting is not configured or if the directory does not exist. If the 
+  path is relative or it starts with "~/" it is interpreted relative to the
+  current user's home directory.
+
+ sieve_trace_level = 
+   The verbosity level of the trace messages. Trace debugging is disabled if
+   this setting is not configured. Possible values are:
+  
+     "actions"  - Only print executed action commands, like keep, fileinto,
+                  reject and redirect.
+     "commands" - Print any executed command, excluding test commands.
+     "tests"    - Print all executed commands and performed tests.
+     "matching" - Print all executed commands, performed tests and the values
+                  matched in those tests.
+
+ sieve_trace_debug = no  
+   Enables highly verbose debugging messages that are usually only useful for
+   developers.
+
+ sieve_trace_addresses = no   
+   Enables showing byte code addresses in the trace output, rather than only
+   the source line numbers.
+
+Sieve Interpreter - Migration from CMUSieve (Dovecot v1.0/v1.1)
+---------------------------------------------------------------
+
+For the most part, migration from CMUSieve to the Pigeonhole LDA Sieve plugin is
+just a matter of changing the used plugin name from 'cmusieve' to 'sieve' in the
+mail_plugins option in the protocol lda section of the config file (as explained
+above). However, there are a few important differences:
+
+ * The imapflags extension is now called imap4flags. The CMUSieve implementation
+   is based on an old draft specification that is not completely compatible.
+   Particularly, the mark and unmark commands were removed from the new
+   specification. For backwards compatibility, support for the old imapflags
+   extension can be enabled using the sieve_extensions setting (as explained
+   above). This is disabled by default.
+
+ * The notify extension is now called enotify. The CMUSieve implementation is
+   based on an old draft specification that is not completely compatible.
+   Particularly, the denotify command and $text$ substitutions were removed from
+   the new specification. For backwards compatibility, support for the old
+   imapflags extension can be enabled using the sieve_extensions setting (as
+   explained above). This is disabled by default.
+
+ * The include extension now requires your script file names to end with
+   ".sieve". This means that ` include :personal "myscript"; ' won't work unless
+   you rename "myscript" to "myscript.sieve"
+
+Sieve Interpreter - Migration from Dovecot Sieve v0.1.x (Dovecot v1.2)
+----------------------------------------------------------------------
+
+ * Dovecot v2.0 adds support for LMTP. Much like the Dovecot LDA, it can make
+   use of the Pigeonhole Sieve plugin. Since the LMTP service has its own
+   prototocol lmtp section in the config file, you need to add the Sieve plugin
+   to the mail_plugins setting there too when you decide to use LMTP.
+ * The 'sieve_subaddress_sep' setting for the Sieve subaddress extension is now
+   known as 'recipient_delimiter'. Although sieve_subaddress_sep is still
+   recognized for backwards compatibility, it is recommended to update the
+   setting to the new name, since the LMTP service also uses the
+   recipient_delimiter setting.
+
+ManageSieve Service - Basic Configuration
+-----------------------------------------
+
+IMPORTANT:
+
+  If you have used the LDA Sieve plugin without ManageSieve before and you have
+  .dovecot.sieve files in user directories, you are advised to make a backup
+  before installing ManageSieve. Although the ManageSieve service takes care to
+  move these files to the Sieve directory before it is substituted with a
+  symbolic link, this is not a very well tested operation, meaning that there is
+  a slim possibility that existing Sieve scripts get lost.
+
+Just like all other binaries that Dovecot uses, the managesieve and
+managesieve-login binaries are installed during make install.
+
+There are two things that have be done to activate the ManageSieve support in
+Dovecot:
+
+ * The first step is to add `sieve' to the protocols= configuration line in
+   your dovecot.conf.
+
+ * The next step is specifying an additional service type for the ManageSieve
+   service. This could be done in Dovecot's conf.d/master.conf or you can use
+   the 20-managesieve.conf file from the doc/example-config/conf.d directory of
+   this package.
+
+   For example:
+
+    service managesieve-login {
+      inet_listener sieve {
+        port = 4190
+      }
+    }
+
+Because the implementation of the ManageSieve daemon is largely based on the
+original IMAP implementation, it is very similar in terms of configuration. The
+following settings can be configured in the 'protocol sieve' section:
+
+ managesieve_max_line_length = 65536
+   The maximum ManageSieve command line length in bytes. This setting is
+   directly borrowed from IMAP. But, since long command lines are very unlikely
+   with ManageSieve, changing this will not be very useful.
+
+ managesieve_logout_format = bytes=%i/%o
+   Specifies the string pattern used to compose the logout message of an
+   authenticated session. The following substitutions are available:
+
+     %i - total number of bytes read from client
+     %o - total number of bytes sent to client
+
+ managesieve_implementation_string = Dovecot Pigeonhole
+   To fool ManageSieve clients that are focused on CMU's timesieved, you can
+   specify the IMPLEMENTATION capability that the Dovecot reports to clients
+   (e.g. 'Cyrus timsieved v2.2.13').
+
+ managesieve_max_compile_errors = 5
+   The maximum number of compile errors that are returned to the client upon
+   script upload or script verification.
+
+ managesieve_sieve_capability =
+ managesieve_notify_capability =
+   Respectively the SIEVE and NOTIFY capabilities reported by the ManageSieve
+   service before authentication. If left unassigned these will be assigned
+   dynamically according to what the Sieve interpreter supports by default
+   (after login this may differ depending on the authenticated user).
+
+Additionally, the ManageSieve service uses the following settings from the
+plugin section of the config file. These settings are the same ones used by
+the LDA Sieve plugin.
+
+ sieve = file:~/sieve;active=~/.dovecot.sieve
+   This specifies the location where the scripts that are uploaded through
+   ManageSieve are stored. During delivery, the LDA Sieve plugin uses this
+   location setting to find the active script for Sieve filtering. The Sieve
+   "include" extension uses this location for retrieving ":personal" scripts.
+   If the location type does not allow uploading scripts, the ManageSieve
+   service cannot be used. Currently, only the 'file' location type supports
+   ManageSieve. 
+
+   For the 'file' location type:
+
+    * The location is the path to the storage directory for all the user's
+      personal Sieve scripts. Scripts are stored as separate files with
+      extension .sieve. All other files are ignored when scripts are listed
+      by a ManageSieve client. The storage directory is always generated
+      automatically if it does not exist (as far as the system permits the
+      user to do so; no root privileges are used). This is similar to the
+      behavior of the mail daemons regarding the mail_location configuration.
+   
+    * ManageSieve maintains a symbolic link pointing to the currently active
+      script (the script executed at delivery). The location of this symbolic
+      link can be configured using the ;active=<path> option. If a regular
+      file already exists at the location specified by in the ;active=<path>
+      location option, it is moved to the storage directory before the
+      symbolic link is installed. It is renamed to dovecot.orig.sieve and
+      therefore listed as dovecot.orig by a ManageSieve client.
+
+      NOTE: It is not wise to place this active symbolic link inside your
+            mail store, as it may be mistaken for a mail folder. Inside a
+            maildir for instance, the default .dovecot.sieve would show up
+            as phantom folder /dovecot/sieve in your IMAP tree. 
+
+   For Pigeonhole versions before v0.3.1, this setting can only be a
+   filesystem path pointing to a script file, or - when ManageSieve is used -
+   it is the location of the symbolic link pointing to the active script in
+   the storage directory. That storage directory is then configured using the
+   deprecated `sieve_dir' setting. 
+
+The following provides an example configuration for Sieve and ManageSieve. Only
+sections and settings relevant to ManageSieve are shown. Refer to
+20-managesieve.conf in the doc/example-config/conf.d directory for a full
+example with comments, but don't forget to configure Sieve and add sieve to the
+'protocols = ...' setting if you use it.
+
+# *** conf.d/20-managesieve.conf ***
+
+service managesieve-login {
+  inet_listener sieve {
+    # Bind the daemon only to the specified address(es)
+    # (default: *, ::)
+    address = 127.0.0.1
+    # Specify an alternative port the daemon must listen on
+    # (default: 4190)
+    port = 2000
+  }
+}
+
+protocol sieve {
+  managesieve_max_compile_errors = 10
+}
+
+# ***  conf.d/90-sieve.conf ***
+
+plugin {
+  sieve=file:~/sieve;active=~/.dovecot.sieve
+}
+
+# *** dovecot.conf ***
+
+# .... (other config items)
+
+# Start imap, pop3, lmtp and managesieve services
+protocols = imap pop3 lmtp sieve
+
+# .... (other config items)
+
+ManageSieve Service - Quota Support
+-----------------------------------
+
+By default, users can manage an unlimited number of Sieve scripts on the server
+through ManageSieve. However, ManageSieve can be configured to enforce limits on
+the number of personal Sieve scripts per user and/or the amount of disk storage
+used by these scripts. The maximum size of individual uploaded scripts is
+dictated by the configuration of the Sieve plugin. The limits are configured in
+the plugin section of the Dovecot configuration as follows:
+
+ sieve_max_script_size = 1M
+   The maximum size of a Sieve script. If set to 0, no limit on the script size
+   is enforced.
+
+ sieve_quota_max_scripts = 0
+   The maximum number of personal Sieve scripts a single user can have. If set
+   to 0, no limit on the number of scripts is enforced.
+
+ sieve_quota_max_storage = 0
+   The maximum amount of disk storage a single user's scripts may occupy. If set
+   to 0, no limit on the used amount of disk storage is enforced.
+
+ManageSieve Service - Proxying
+------------------------------
+
+Like Dovecot's imapd, the ManageSieve login daemon supports proxying to multiple
+backend servers. Although the underlying code is copied from the imapd sources
+for the most part, it has some ManageSieve-specifics that have not seen much
+testing.
+
+The proxy configuration wiki page for POP3 and IMAP should apply to ManageSieve
+as well:
+
+http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy
+
+ManageSieve Service - Migration
+-------------------------------
+
+The following has changed since the ManageSieve releases for Dovecot v1.x:
+
+ * For Dovecot v1.0 and v1.1, the sieve_dir setting used by ManageSieve was
+   called sieve_storage. Also, the sieve and sieve_storage settings were located
+   inside the 'protocol managesieve' section of the configuration. As per
+   Dovecot v1.2, these settings are shared with the Sieve plugin and located in
+   the 'plugin' section of the configuration. Make sure you have updated the
+   name of the sieve_dir setting and the location of both these settings if you
+   are upgrading from ManageSieve for Dovecot v1.0/v1.1.
+ * Pigeonhole ManageSieve does not use the mail_location configuration as a
+   fall-back anymore to determine a default location for storing Sieve scripts.
+   It always uses the sieve_dir setting, with default value ~/sieve.
+ * The Pigeonhole ManageSieve service now binds to TCP port 4190 by default due
+   to the IANA port assignment for the ManageSieve service. When upgrading from
+   v1.x, this should be taken into account. For a smooth transition, the service
+   can be configured manually to listen on both port 2000 and port 4190, as
+   demonstrated in the example above.
+ * The Dovecot configuration now calls the ManageSieve protocol 'sieve' instead
+   of 'managesieve' because it is registered as such with IANA. The binaries and
+   the services are still called 'managesieve' and 'managesieve-login'. The
+   example above demonstrates how this affects the configuration.
+
+Test Suite
+==========
+
+This package includes a test suite to verify the basic processing of the Sieve
+interpreter on your particular platform. Note that the test suite is not
+available when this package is compiled against the Dovecot headers only. The
+test suite executes a list of test cases and halts when one of them fails. If it
+executes all test cases successfully, the test suite finishes. You can execute
+the basic test suite using `make test`, which does not include the plugins. You
+can test the plugins using `make test-plugins`.
+
+A failing test case is always a bug and a report is greatly appreciated.

+v0.5.21 2023-08-15  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	- sieve: Using the deleteheader action on a message with a broken/invalid
+	  header can cause the Sieve interpreter to crash with an assert panic.
+	  This can happen e.g. when the message is missing the empty EOH line
+	  between the headers and the body of the message. Fixes:
+	  Panic: file edit-mail.c: line 820 (edit_mail_headers_parse):
+	  assertion failed: (body_offset > 0).
+	- sieve: Pigeonhole added an extra Message-ID header during mail
+	  forwarding when the existing one was invalid. Now it adds the
+	  Message-ID only if it is entirely missing. Existing Message-ID(s) are
+	  left unchanged.
+
+v0.5.20 2022-12-12  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	* No changes - release done to keep version numbers synced.
+
+v0.5.19  2022-05-10  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	* No changes - release done to keep version numbers synced.
+
+v0.5.18  2022-02-03  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	- duplicate: Users without a home directory can crash with Sieve when
+	  using duplicate database. v2.3.17 regression.
+	- imapsieve: When mail was expunged when processing imapsieve events, a
+	  crash could occur. Fixes Panic: file mail-index-map.c:
+	  line 558 (mail_index_map_lookup_seq_range): assertion failed: (first_uid > 0)
+	- managesieve-login: Proxy didn't support forwarding the forward_* passdb fields.
+	- redirect: Sieve would crash if redirect after keep-equivalent action failed.
+	- sieve: Interpreter crashes when the Sieve index extension is used with
+	  index zero.
+	- vnd.dovecot.filter: Envelope sender string may become corrupted when
+	  Sieve scripts are using vnd.dovecot.filter. This could end up
+	  corrupting mbox's From line and return wrong envelope sender string in
+	  Sieve tests.
+
+v0.5.17.1 2021-12-07  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	- managesieve: Dovecot failed to start if ssl_ca was too large.
+	- lib-sieve-tool: Binaries failed to run if ssl_ca was too large.
+
+v0.5.17 2021-10-28  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	- duplicate: The Sieve duplicate test is prone to false negatives when
+	  the user receives many e-mails concurrently, meaning that duplicate
+	  deliveries can still occur.
+	- fileinto: v2.3.16 regression: Sieve delivery crashes if mail is
+	  delivered to non-existing and existing folder.
+	- imap-filter-sieve: v2.3.15 regression: The CPU limits on Sieve
+	  execution are too easily exceeded in IMAP context (the IMAPSieve and
+	  FILTER=SIEVE capabilities). Changed the default to unlimited CPU time
+	  for IMAP context, since similar excessive resource usage can be caused
+	  by other means as well. The CPU limits on Sieve scripts executed at
+	  LDA/LMTP delivery are still enforced by default.
+	- redirect:  The Sieve redirect action has protections against users
+	  triggering mail loops. Unfortunately, the detection of a redirect mail
+	  loop sometimes causes the message to get lost if no other Sieve action
+	  is applied that delivers the message somewhere else.
+	- redirect: v2.3.16 regression: With certain Sieve scripts if redirect
+	  fails due to temporary failure, the lmtp process may crash after the
+	  delivery. Fixes:
+	  Panic: file mail-user.c: line 229 (mail_user_deinit):
+	  assertion failed: ((*user)->refcount == 1).
+
+v0.5.16 2021-08-06  Timo Sirainen <timo.sirainen@open-xchange.com>
+
+	* .dovecot.sieve.log file now includes year in the header.
+	* Change Sieve script result execution to delay definitive action
+	  execution to the end of a successful Sieve script execution session.
+	  This is part of an effort to solve problems with the Sieve duplicate
+	  test. As a side-effect, some rare temporary-error cases yield
+	  different results, in which partial failure is more likely.
+
+v0.5.15 2021-06-21  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	* CVE-2020-28200: Sieve interpreter is not protected against abusive
+	  scripts that claim excessive resource usage. Fixed by limiting the
+	  user CPU time per single script execution and cumulatively over
+	  several script runs within a configurable timeout period. Sufficiently
+	  large CPU time usage is summed in the Sieve script binary and execution
+	  is blocked when the sum exceeds the limit within that time. The block
+	  is lifted when the script is updated after the resource usage times out.
+	* Disconnection log messages are now more standardized across services.
+	  They also always now start with "Disconnected" prefix.
+	- managesieve: Commands pipelined together with and just after the
+	  authenticate command cause these commands to be executed twice.
+
+v0.5.14 2021-03-04  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	* IMAP FILTER command: cmd-filter-sieve - Do not allow NIL as
+	  script name argument.
+
+v0.5.13 2021-01-04  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	- duplicate: The test was handled badly in a multiscript (sieve_before,
+	  sieve_after) scenario in which an earlier script in the sequence with
+	  a duplicate test succeeded, while a later script caused a runtime
+	  failure. In that case, the message is recorded for duplicate tracking,
+	  while the message may not actually have been delivered in the end.
+	- editheader: Sieve interpreter entered infinite loop at startup when
+	  the "editheader" configuration listed an invalid header name. This
+	  problem can only be triggered by the administrator.
+	- relational: The Sieve relational extension can cause a segfault at
+	  compile time. This is triggered by invalid script syntax. The segfault
+	  happens when this match type is the last argument of the test command.
+	  This situation is not possible in a valid script; positional arguments
+	  are normally present after that, which would prevent the segfault.
+	- sieve: For some Sieve commands the provided mailbox name is not
+	  properly checked for UTF-8 validity, which can cause assert crashes at
+	  runtime when an invalid mailbox name is encountered. This can be
+	  caused by the user by writing a bad Sieve script involving the
+	  affected commands ("mailboxexists", "specialuse_exists").
+	  This can be triggered by the remote sender only when the user has
+	  written a Sieve script that passes message content to one of the
+	  affected commands.
+	- sieve: Large sequences of 8-bit octets passed to certain Sieve
+	  commands that create or modify message headers that allow UTF-8 text
+	  (vacation, notify and addheader) can cause the delivery or IMAP
+	  process (when IMAPSieve is used) to enter a memory-consuming
+	  semi-infinite loop that ends when the process exceeds its memory
+	  limits. Logged in users can cause these hangs only for their own
+	  processes.
+
+v0.5.11 2020-08-12  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	* managesieve: managesieve_max_line_length setting is now a "size" type
+	  instead of just number of bytes. This allows using e.g. "64k" as the
+	  value.
+	- lib-sieve: When folding white space is used in the Message-ID header,
+	  it is not stripped away correctly before the message ID value is used,
+	  causing e.g. garbled log lines at delivery.
+
+v0.5.10 2020-03-06  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	* imap_sieve_filter: Change result action logging to include IMAP UID
+	- vacation: Addresses were compared case-sensitively.
+
+v0.5.9 2019-12-04  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	+ Added events for Sieve and ManageSieve, see
+	  https://doc.dovecot.org/admin_manual/list_of_events/#pigeonhole
+	+ Pigeonhole: Implement the Sieve "special-use" extension described in
+	  RFC 8579.
+	- duplicate: Test only compared the handles which would cause
+	  different values to be cached as the same duplicate test. Fix to also
+	  compare the actual hashes.
+	- imap_sieve_filter: IMAP FILTER Command had various bugs in error
+	  handling. Errors may have been duplicated for each email, errors
+	  may have been missing entirely, command tag and ERRORS/WARNINGS
+	  parameters were swapped.
+
+v0.5.8 2019-10-08  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	- Sieve may leak resources in rare cases when a redirect, vacation or
+	  report action fails to send the message. This mainly applies when
+	  Sieve is executed in IMAP context; i.e., for the IMAPSIEVE or
+	  FILTER=SIEVE capabilities.
+
+v0.5.7.1 2019-07-23  Timo Sirainen <timo.sirainen@open-xchange.com>
+
+	- dsync: Sieve script syncing failed if mailbox attributes weren't
+	  enabled.
+
+v0.5.7 2019-07-12  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	+ vacation: Made the subject for the automatic response message produced
+	  by the Sieve vacation action configurable. Both the default subject
+	  (if the script defines none) and the subject template (e.g. used to
+	  add a subject prefix) can be configured.
+	- dsync: dsync-replication does not synchronize Sieve scripts.
+	- imap_sieve_filter: Reduce FILTER=SIEVE verbosity over IMAP connection.
+	- testsuite: Pigeonhole testsuite segfaulted if it was compiled with
+	  GCC 9
+
+v0.5.6 2019-04-30  Aki Tuomi <aki.tuomi@open-xchange.com>
+
+	+ sieve: Redirect loop prevention is sometimes ineffective. Improve
+	  existing loop detection by also recognizing the
+	  X-Sieve-Redirected-From header in incoming messages and dropping
+	  redirect actions when it points to the sending account. This header
+	  is already added by the redirect action, so this improvement only
+	  adds an additional use of this header.
+	- sieve: Prevent execution of implicit keep upon temporary failure
+	  occurring at runtime.
+
+v0.5.5 2019-03-05  Stephan Bosch <stephan@rename-it.nl>
+
+	+ IMAPSieve: Add new plugin/imapsieve_expunge_discarded setting which
+	  causes messages discarded by an IMAPSieve script to be expunged
+	  immediately, rather than only being marked as "\Deleted" (which is
+	  still the default behavior).
+	- IMAPSieve: Fix panic crash occurring when a COPY command copies
+	  messages from a virtual mailbox where the source messages originate
+	  from more than a single real mailbox.
+	- imap4flags extension: Fix deleting all keywords. When the action
+	  resulted in all keywords being removed, no changes were actually
+	  applied.
+	- variables extension: Fix truncation of UTF-8 variable content. The
+	  maximum size of Sieve variables was enforced by truncating the
+	  variable string content bluntly at the limit, but this does not
+	  consider UTF-8 code point boundaries. This resulted in broken UTF-8
+	  strings. This problem also surfaced for variable modifiers, such as
+	  the ":encodeurl" modifier provided by the Sieve "enotify" extension.
+	  In that case, the resulting URI escaping could also be truncated
+	  inappropriately.
+	- IMAPSieve, IMAP FILTER=SIEVE: Fix replacing a modified message. Sieve
+	  scripts running in IMAPSIEVE or IMAP FILTER=SIEVE context that
+	  modify the message, stored the message a second time, rather than
+	  replacing the originally stored unmodified message.
+	- Fix segmentation fault occurring when both the sieve_extprograms
+	  plugin (for the Sieve interpreter) and the imap_filter_sieve plugin
+	  (for IMAP) are loaded at the same time. A symbol was defined by both
+	  plugins, causing a clash when both were loaded.
+
+v0.5.4 2018-11-23  Stephan Bosch <stephan@rename-it.nl>
+
+	* Adjustments to several changes in Dovecot v2.3.4 make this Pigeonhole
+	  release dependent on that Dovecot release; it will not compile against
+	  older Dovecot versions. And, conversely, you need to upgrade
+	  Pigeonhole when upgrading Dovecot to v2.3.4.
+	* The changes regarding the default postmaster_address in Dovecot v2.3.4
+	  mainly apply to Pigeonhole. The new default should work for all
+	  existing installations, thereby fixing several reported v2.3/v0.5
+	  migration problems.
+	- IMAP FILTER=SIEVE capability: Fix assert crash occurring when running
+	  UID FILTER on a Sieve script with errors.
+
+v0.5.3 2018-10-01  Stephan Bosch <stephan@rename-it.nl>
+
+	- Fix assertion panic occurring when managesieve service fails to open
+	  INBOX while saving a Sieve script. This was caused by a lack of
+	  cleanup after failure.
+	- Fix specific messages causing an assert panic with actions that
+	  compose a reply (e.g. vacation). With some rather weird input from the
+	  original message, the header folding algorithm (as used for composing
+	  the References header for the reply) got confused, causing the panic.
+	- IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command parsing.
+	  After finishing reading the Sieve script, the command parsing
+	  sometimes didn't continue with the search arguments. This is a time-
+	  critical bug that likely only occurs when the Sieve script is sent in
+	  the next TCP frame.
+
+v0.5.2 2018-06-29  Stephan Bosch <stephan@rename-it.nl>
+
+	+ Implement plugin for the a vendor-defined IMAP capability called
+	  "FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering
+	  in IMAP. More information can be found in
+	  doc/plugins/imap_filter_sieve.txt.
+	- The Sieve addess test caused an assertion panic for invalid addresses
+	  with UTF-8 codepoints in the localpart. Fixed by properly detecting
+	  invalid addresses with UTF-8 codepoints in the localpart and skipping
+	  these like other invalid addresses while iterating addresses for the
+	  address test.
+	- Make the length of the subject header for the vacation response
+	  configurable and enforce the limit in UTF-8 codepoints rather than
+	  bytes. The subject header for a vacation response was statically
+	  truncated to 256 bytes, which is too limited for multi-byte UTF-8
+	  characters.
+	- Sieve editheader extension: Fix assertion panic occurring when it is
+	  used to manipulate a message header with a very large header field.
+	- Properly abort execution of the sieve_discard script upon error.
+	  Before, the LDA Sieve plugin attempted to execute the sieve_discard
+	  script when an error occurs. This can lead to the message being lost.
+	- Fix the interaction between quota and the sieve_discard script. When
+	  quota was used together with a sieve_discard script, the message
+	  delivery did not bounce when the quota was exceeded.
+
+v0.5.1 28-03-2018  Stephan Bosch <stephan@rename-it.nl>
+
+	- Explicitly disallow UTF-8 in localpart in addresses parsed from Sieve
+	  script.
+	- editheader extension: Corrected the stream position calculations
+	  performed while making the modified message available as a stream.
+	  Pigeonhole Sieve crashed in LMTP with an assertion panic when the
+	  Sieve editheader extension was used before the message was redirected.
+	  Experiments indicate that the problem occurred only with LMTP and that
+	  LDA is not affected.
+	- fileinto extension: Fix assert panic occurring when fileinto is used
+	  without being listed in the require line, while the copy extension is
+	  listed there. This is a very old bug.
+	- imapsieve plugin: Do not assert crash or log an error for messages
+	  that disappear concurrently while applying Sieve scripts. This event
+	  is now logged as a debug message.
+	- Sieve extprograms plugin: Large output from "execute" command crashed
+	  delivery. Fixed buffering issue in code that handles output from the
+	  external program.
+
+v0.5.0.1 05-01-2018  Stephan Bosch <stephan@rename-it.nl>
+
+	- imap4flags extension: Fix binary corruption occurring when
+	  setflag/addflag/removeflag flag-list is a variable.
+	- sieve-extprograms plugin: Fix segfault occurring when used in
+	  IMAPSieve context.
+
+v0.5.0 24-12-2017  Stephan Bosch <stephan@rename-it.nl>
+
+	* editheader extension: The implementation of header modifications is
+	  heavily updated. Although the functionality has not changed, the
+	  underlying code was updated to address several static analysis
+	  warnings, runtime integer arithmetic warnings (Clang), and to match
+	  updates in the Dovecot stream API.
+	+ variables extension: Made the maximum scope and variable size
+	  configurable.
+	+ subaddress: Support multiple recipient_delimiters.
+	- enotify extension: mailto method: Fixed parsing of mailto URI with
+	  only a header part.
+	- enotify plugin: mailto method: Make sure the "From:" header is set to
+	  a usable address and not "(null)".
+	- Fixed writing address headers to outgoing messages. Sometimes headers
+	  were MIME-encoded twice, yielding invalid results.
+
+v0.4.23 20-03-2018  Stephan Bosch <stephan@rename-it.nl>
+
+	- editheader extension: Corrected the stream position calculations
+	  performed while making the modified message available as a stream.
+	  Pigeonhole Sieve crashed in LMTP with an assertion panic when the
+	  Sieve editheader extension was used before the message was redirected.
+	  Experiments indicate that the problem occurred only with LMTP and that
+	  LDA is not affected.
+	- fileinto extension: Fix assert panic occurring when fileinto is used
+	  without being listed in the require line, while the copy extension is
+	  listed there. This is a very old bug.
+	- imapsieve plugin: Do not log an error for messages that disappear
+	  concurrently while applying Sieve scripts. This is a further
+	  improvement on the imapsieve fix in the previous release (which fixed
+	  a panic). This event is now logged as a debug message.
+
+v0.4.22 01-03-2018  Stephan Bosch <stephan@rename-it.nl>
+
+	- Fixed filesystem path handling problem: sieve plugin could have
+	  assert-crashed with specific path lengths with: "Panic: file
+	  realpath.c: line 86 (path_normalize): assertion failed: (npath_pos +
+	  1 < npath + asize)".
+	- Sieve extprograms plugin: Large output from "execute" command crashed
+	  delivery. Fixed buffering issue in code that handles output from the
+	  external program.
+	- editheader extension: Extensively reworked the low-level
+	  implementation of adding and removing headers. This solves a few
+	  integer arithmetic problems reported by Clang runtime checks, but also
+	  improves code structure and reliability in general.
+	- imapsieve: Fix assert crash occurring when selected messages are
+	  expunged concurrently by the time Sieve filter is to be applied.
+	- imap4flags extension: Fix binary byte-code corruption occurring when
+	  the setflag, addflag, or removeflag command's flag-list is a variable.
+	- enotify extension: mailto method: Fixed parsing of mailto URI with
+	  only a header part.
+	- enotify extension: mailto method: Make sure "From:" header is set to a
+	  usable address and not "(null)".
+	- Fixed writing address headers to outgoing messages. It sometimes
+	  erroneously applied another layer of MIME header encoding.
+
+v0.4.21 12-10-2017 Stephan Bosch <stephan@rename-it.nl>
+
+	* redirect action: Always set the X-Sieve-Redirected-From header to
+	  sieve_user_email if configured. Before, it would use the envelope recipient
+	  instead if available, which makes no sense if the primary e-mail address is
+	  available.
+	+ vacation extension: Allow ignoring the envelope sender while composing the
+	  "To:" header for the reply. Normally, the "To:" header is composed from
+	  the address found in the "Sender", "Resent-From" or "From" headers that is
+	  equal to the envelope sender. If none is then found, the bare envelope
+	  sender is used. This change adds a new setting
+	  "sieve_vacation_to_header_ignore_envelope". With this setting enabled, the
+	  "To:" header is always composed from those headers in the source message.
+	  The new setting thus allows ignoring the envelope, which is useful e.g.
+	  when SRS is used.
+	+ vacation extension: Compose the "To:" header from the full sender address
+	  found in the first "Sender:", "From:" or "Resent-From:" header. Before, it
+	  would create a "To:" header without a phrase part. The new behavior is
+	  nicer, since the reply will be addressed to the sender by name if possible.
+	- LDA Sieve plugin: Fixed sequential execution of LDAP-based scripts. A
+	  missing LDAP-based script could cause the script sequence to exit earlier.
+	- sieve-filter: Removed the (now) duplicate utf8 to mutf7 mailbox name
+	  conversion. This caused problems with mailbox names containing UTF-8
+	  characters. The Dovecot API was changed years ago, but apparently
+	  sieve-filter was never updated.
+
+v0.4.20 27-08-2017 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Made the retention period for redirect duplicate identifiers configurable.
+	  For accounts that perform many redirects, the lda-dupes database could grow
+	  to impractical sizes. Changed the default retention period from 24 to 12
+	  hours.
+	- sieve-filter: Fixed memory leak: forgot to clean up script binary at end of
+	  execution. Normally, this would merely be an inconsequential memory leak.
+	  However, when the script comes from an LDAP storage, this would cause io
+	  leak warnings.
+	- managesieve-login: Fixed handling of AUTHENTICATE command. A second
+	  authenticate command would be parsed wrong. This problem was caused by
+	  changes in the previous release.
+	- LDA Sieve plugin: Fixed minor memory leak caused by not cleaning up the
+	  sieve_discard script.
+
+v0.4.19 26-06-2017 Stephan Bosch <stephan@rename-it.nl>
+
+	* This release adjusts Pigeonhole to several changes in the Dovecot API,
+	  making it depend on Dovecot v2.2.31. Previous versions of Pigeonhole will
+	  produce compile warnings with the recent Dovecot releases (but still work
+	  ok).
+	- Fixed bug in handling of implicit keep in some cases. Implicit side-effects,
+	  such as assigned flags, were not always applied correctly. This is in
+	  essence a very old bug, but it was exposed by recent changes.
+	- include extension: Fixed segfault that (sometimes) occurred when the global
+	  script location was left unconfigured.
+
+v0.4.18 12-04-2017 Stephan Bosch <stephan@rename-it.nl>
+
+	+ imapsieve plugin: Implemented the copy_source_after rule action. When this
+	  is enabled for a mailbox rule, the specified Sieve script is executed for
+	  the message in the source mailbox during a "COPY" event. This happens only
+	  after the Sieve script that is executed for the corresponding message in the
+	  destination mailbox finishes running successfully.
+	+ imapsieve plugin: Added non-standard Sieve environment items for the source
+	  and destination mailbox.
+	- multiscript: The execution of the discard script had an implicit "keep",
+	  rather than an implicit "discard".
+
+v0.4.17 26-02-2017 Stephan Bosch <stephan@rename-it.nl>
+
+	- LDA Sieve plugin: Fixed handling of an early explicit keep during
+	  multiscript execution. Action side-effects and the message snapshot would be
+	  lost at the final stage where the implicit keep is evaluated. This could
+	  result in the IMAP flags assigned to the message to be forgotten or that
+	  headers modified by the "editheader" extension would revert to their
+	  original state.
+	- file script storage: Amended the up-to-date time stamp comparison for
+	  on-disk binaries to include nanoseconds. This will fix problems occurring
+	  when both binary and script are saved within the same second. This fix is
+	  ineffective on older systems that have no support for nanoseconds in stat()
+	  timestamps, which	should be pretty rare nowadays.
+	- file script storage: Improve saving and listing permission error to include
+	  more details.
+	- imapsieve plugin: Make sure "INBOX" is upper case in static mailbox rules.
+	  Otherwise, the mailbox name would never match, since matching is performed
+	  case-sensitively and Dovecot only returns the upper-cased "INBOX".
+	- imapsieve plugin: Fixed assert failure occurring when used with virtual
+	  mailboxes.
+	- doveadm sieve plugin: Fixed crash when setting Sieve script via attribute's
+	  string value.
+
+v0.4.16 30-10-2016 Stephan Bosch <stephan@rename-it.nl>
+
+	* Part of the Sieve extprograms implementation was moved to Dovecot, which
+	  means that this release depends on Dovecot v2.2.26+.
+	* ManageSieve: The PUTSCRIPT command now allows uploading empty Sieve scripts.
+	  There was really no good reason to disallow doing that.
+	+ Sieve vnd.dovecot.report extension:
+	  + Added a Dovecot-Reporting-User field to the report body, which contains
+	    the e-mail address of the user sending the report.
+	  + Added support for configuring the "From:" address used in the report.
+	+ LDA sieve plugin: Implemented support for a "discard script" that is run
+	  when the message is going to be discarded. This allows doing something other
+	  than throwing the message away for good.
+	+ Sieve vnd.dovecot.environment extension: Added vnd.dovecot.config.*
+	  environment items. These environment items map to sieve_env_* settings from
+	  the plugin {} section in the configuration. Such values can of course also
+	  be returned from userdb.
+	+ Sieve vacation extension: Use the Microsoft X-Auto-Response-Suppress header
+	  to prevent unwanted responses from and to (older) Microsoft products.
+	+ ManageSieve: Added rawlog_dir setting to store ManageSieve traffic logs.
+	  This replaces at least partially the rawlog plugin (mimics similar IMAP/POP3
+	  change).
+	- doveadm sieve plugin: synchronization: Prevent setting file timestamps to
+	  unix epoch time. This occurred when Dovecot passed the timestamp as
+	  'unknown' during synchronization.
+	- Sieve exprograms plugin: Fixed spurious '+' sometimes returned at the end
+	  of socket-based program output.
+	- imapsieve plugin: Fixed crash occurring in specific situations.
+	- Performed various fixes based on static analysis and Clang warnings.
+
+v0.4.15 07-07-2016 Stephan Bosch <stephan@rename-it.nl>
+
+	* vacation extension: The sieve_user_email setting is now used in the check
+	  for implicit delivery.
+	- imapsieve plugin: For any mail transaction, the mailbox was opened a second
+	  time, even if no mailbox rule matched. This was unintentional, useless and
+	  caused problems when the imapsieve plugin was used with other plugins like
+	  acl.
+	- extprograms plugin: Significantly improved error handling. No stream errors
+	  were logged.
+	- extprograms plugin: Fixed bug in handling of result code from remote program
+	  (script service).
+	- extprograms plugin: Connection to remote program service was not retried.
+	- Several small fixes based on static analysis.
+	- Fixed handling of quoted string localparts in email addresses.
+
+v0.4.14 26-04-2016 Stephan Bosch <stephan@rename-it.nl>
+
+	* The address test now allows specifying the X-Original-To header.
+	+ Implemented the Sieve imapsieve extension and its IMAP counterpart
+	  (RFC 6785) as a set of plugins. This allows running Sieve scripts at IMAP
+	  activity, rather than at delivery. There are also facilities for the
+	  familiar sieve_before/sieve_after administrator scripts. A user script is
+	  defined for a mailbox using an IMAP METADATA entry, whereas administrator
+	  scripts are configured using mailbox matching rules defined in the plugin
+	  settings.
+	+ Adjusted the Sieve ihave extension to allow capability tests to be performed
+	  at runtime. This way, scripts can be written that work both at delivery and
+	  from IMAP.
+	+ Implemented support for runtime trace debugging. This means that detailed
+	  information about which commands, actions and tests are performed is written
+	  to a file. That file is created in the configured directory, but only if
+	  that directory exists. This way, a particular user can be easily singled out
+	  for debugging. This works much like the Dovecot rawlog facility. The trace
+	  output is identical to what is produced using sieve-test with its "-t"
+	  command line option.
+	+ Added a "sieve_user_email" setting that configures the user's primary email
+	  address. This is mainly useful to have a user email address available in
+	  IMAP, where envelope data is unavailable.
+	+ Implemented the dovecot-specific "vnd.dovecot.report" extension. This allows
+	  sending report messages in the Message Abuse Reporting Format (RFC 5965).
+	- extprograms plugin: Fixed epoll() panic caused by closing the output FD
+	  before the output stream.
+	- Made sure that the local part of a mail address is encoded properly using
+	  quoted string syntax when it is not a dot-atom.
+
+v0.4.13 18-03-2016 Stephan Bosch <stephan@rename-it.nl>
+
+	* redirect action: Added the list-id header to the duplicate ID for mail loop
+	  prevention. This means that the message sent directly to the user and the
+	  message coming through the mailing list itself are treated as different
+	  messages by the loop detection of the redirect command, even though their
+	  Message-ID may be identical.
+	* Changed the Sieve number type to uint64_t, which means that Sieve numbers
+	  can now technically range up to 2^64. Some other Sieve implementation
+	  allowed this, making this change necessary for successful migration.
+	+ Implemented the sieve_implicit_extensions setting. The extensions listed in
+	  this setting do not need to be enabled explicitly using the Sieve "require"
+	  command. This behavior directly violates the standard, but can be necessary
+	  for compatibility with some existing implementations of Sieve. Do not use
+	  this setting unless you really need to!
+	- redirect action: Made mail loop detection more robust by forcibly adding a
+	  Message-ID header if it is missing.
+	- Prevent logging a useless "script not found" error message for LDAP scripts
+	  for which the entry exists but no attribute containing a script. This is not
+	  necessarily an error.
+	- extprograms plugin: Changed the communication channel between parent and
+	  child process for a directly forked program from a socketpair to a double
+	  pipe. Linux does not support /dev/stdin, /dev/stdout and friends for
+	  sockets. For some shell program authors this may be confusing, so that is
+	  why it is changed. When using the script service, these device nodes are
+	  still not usable though.
+
+v0.4.12 06-02-2016 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Implemented the Sieve extracttext extension (RFC 5703; Section 7). It is now
+	  possible to extract body text from a message into a variable.
+	* Increased ABI version due to changes in the Sieve interpreter's object
+	  definitions.
+	- multiscript: Fixed bug in handling of (implicit) keep; final keep action was
+	  always executed as though there was a failure. This caused the keep action
+	  to revert back to the initial message, causing editheader actions to be
+	  ignored.
+	- managesieve-login: Fixed proxy to allow SASL mechanisms other than PLAIN.
+	  Before, the proxy would fail if the server did not support the PLAIN
+	  mechanism.
+	- ldap storage: Prevent segfault occurring when assigning certain (global)
+	  configuration options.
+
+v0.4.11 08-01-2016 Stephan Bosch <stephan@rename-it.nl>
+
+	- Sieve mime extension: Fixed the header :mime :anychild test to work properly
+	  outside a foreverypart loop.
+	- Several fixes in message body part handling:
+	  - Fixed assert failure occurring when text extraction is attempted on a
+	    empty or broken text part.
+	  - Fixed assert failure in handling of body parts that are converted to text.
+	  - Fixed header unfolding for (mime) headers parsed from any mime part.
+	  - Fixed trimming for (mime) headers parsed from any mime part.
+	  - Fixed erroneous changes to the message part tree structure performed when
+	    re-parsing the message.
+	- LDA Sieve plugin: Fixed logging of actions; sometimes the configured log
+	  format was not followed.
+	- LDA Sieve plugin: Fixed bug in error handling of script storage
+	  initialization.
+	- Sieve Extprograms plugin: Ignored ENOTCONN error in shutdown(fd, SHUT_WR)
+	  call.
+	- Fixed duplication of discard actions in the script result. Each discard was
+	  counted as a separate action, which means that action limit would be crossed
+	  too early.
+	- Made sure that quota errors never get logged as errors in syslog.
+	- Fixed handling of implicit keep for a partially executed transaction that
+	  yielded a temporary failure.
+	- Fixed handling of global errors. If master and user error handler were
+	  identical, in some cases the log message could be lost.
+	- Fixed AIX compile issue in message body parser.
+
+v0.4.10 13-12-2015 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Implemented the Sieve mime and foreverypart extensions (RFC 5703). These
+	  are fully implemented. The interaction with the editheader extension needs
+	  some work, but this should not influence most uses; i.e., changes by the
+	  editheader extension are not always visible using foreverypart/mime.
+	+ Sieve body extension: Properly implemented the `:text' body transform. It
+	  now extracts text for HTML message parts.
+	+ Sieve enotify extension: mailto method: Implemented the
+	  sieve_notify_mailto_envelope_from setting. This allows configuring the
+	  source of the notification sender address for e-mail notifications. This is
+	  similar to what already can be configured for redirect.
+	+ Added a sieve_enabled (defaults to 'yes') setting that allows explicitly
+	  disabling Sieve processing for particular users. This used to be possible by
+	  setting `sieve=', but ever since the sieve_before, sieve_after and
+	  sieve_default settings were added, this method was not reliable anymore.
+	- variables extension: Fixed handling of empty string by the `:length' set
+	  modifier. An empty string yielded an empty string rather than "0".
+	- Fixed memory leak in the Sieve script byte code dumping facility. Extension
+	  contexts were never actually freed.
+	- Fixed handling of implicit keep when the last Sieve script is a global one.
+	  In that case the implicit keep action was executed in global context, which
+	  could mean that trivial (quota) errors ended up in the system log file,
+	  rather than the user log file.
+	- doveadm sieve plugin: Fixed crashes caused by incorrect context allocation
+	  in the sieve command implementations.
+
+v0.4.9 04-10-2015 Stephan Bosch <stephan@rename-it.nl>
+
+	* Properly implemented checking of ABI version for Sieve interpreter plugins,
+	  much like Dovecot itself does for plugins. This will prevent plugin ABI
+	  mismatches. 
+	+ Implemented a vnd.dovecot.environment extension. This builds upon the
+	  standard environment extension and adds a few more environment items, such
+	  as username and default mailbox. It also creates a variables namespace so
+	  that environment items can be accessed directly. I am still thinking about
+	  more environment items that can be added.
+	+ Sieve extprograms plugin: Made line endings of the input passed to the
+	  external programs configurable. This can be configured separately for each
+	  of the three extensions.
+	+ ManageSieve: Implemented proxy XCLIENT support. This allows the proxy to
+	  pass client information to the back-end.
+	- ManageSieve: Fixed an assert failure occurring when a client disconnects
+	  during the GETSCRIPT command.
+	- doveadm sieve plugin: Fixed incorrect initialization of mail user. This
+	  caused a few memory leaks.
+	- sieve-filter command line tool: Fixed handling of failure-related implicit
+	  keep when there is an explicit default destination folder. This caused
+	  message duplication.
+	- lib-sieve: Fixed bug in RFC5322 header folding. Words longer than the
+	  optimal line length caused empty lines in the output, which would break the
+	  resulting message header. This surfaced in References: headers with very
+	  long message IDs.
+
+v0.4.8 15-05-2015 Stephan Bosch <stephan@rename-it.nl>
+
+	* LDA Sieve plugin: Dovecot changed the deliver_log_format setting to include
+	  %{delivery_time}. This prompted changes in Pigeonhole that make this release
+	  dependent on Dovecot v2.2.17.
+	+ Implemented magic to make sieve_default script visible from ManageSieve
+	  under a configurable name. This way, users can see the default rules, edit
+	  them and store a private adjusted version. This could also be achieved by
+	  copying the default script into the user's script storage, but updates to
+	  the global sieve_default script would be ignored that way.
+	+ ManageSieve: Implemented support for reporting command statistics at
+	  disconnect. Statistics include the number of bytes and scripts uploaded/
+	  downloaded/checked and the number of scripts deleted/renamed.
+	- Fixed problem in address test: erroneously decoded mime-encoded words in
+	  address headers.
+	- extprograms plugin: Fixed failure occurring when connecting to script
+	  service without the need to read back the output from the external program.
+	- Fixed bug in script storage path normalization occurring with relative
+	  symbolic links below root.
+	- Fixed and updated various parts of the documentation 
+	- ManageSieve: Used "managesieve" rather than "sieve" as login service name,
+	  which means that all managesieve-specific settings where ignored.
+	- Managesieve: Storage quota was not always enforced properly for scripts
+	  uploaded as quoted string. Nobody uses that, but it is allowed in the
+	  specification and we support it, so it should work properly.
+
+v0.4.7 19-03-2015 Stephan Bosch <stephan@rename-it.nl>
+
+	* editheader extension: Made protection against addition and deletion of
+	  headers configurable separately. Also, the `Received' and `Auto-Submitted'
+	  headers are no longer protected against addition by default.
+	* Turned message envelope address parse errors into warnings.
+	* The interpreter now accepts non-standard domain names, e.g. containing '_'.
+	+ Implemented the Sieve index extension (RFC 5260).
+	+ Implemented support for the mboxmetadata and servermetadata extensions
+	  (RFC 5490).
+	+ Implemented new sieve commands for the doveadm command line utility. These
+	  commands are currently limited to ManageSieve operations, but the other
+	  current sieve tools will be migrated to doveadm in the near future as well.
+	+ Added more debug output about binary up-to-date checking.
+	+ Added script metadata to binary dump output.
+	- Fixed Sieve script binary up-to-date checking by normalizing the script
+	  location.
+	- The Sieve interpreter now flushes the duplicate database during start phase
+	  of result execution rather than commit phase. This makes sure locks on the
+	  duplicate database are released as soon as possible, preventing contention.
+	- Performed a few optimizations in the lexical scanner of the language.
+	- Fixed bug in `:matches' match-type that made a pattern without
+	  wildcards match as if there were a '*' at the beginning.
+	- Fixed crash in validation of the string parameter of the comparator tag.
+	- extprograms extension: Made sure supplemental group privileges are also
+	  dropped. This was a problem reported by Debian lintian.
+	- Fixed bug in handling of binary errors for action side-effects and message
+	  overrides.
+	- file script storage: Restructured storage initialization to address
+	  backwards compatibility issues.
+	- dict script storage: Fixed small memory allocation bug.
+
+v0.4.6 02-11-2014 Stephan Bosch <stephan@rename-it.nl>
+
+	- After make distclean the distributed tarball would fail to recompile.
+	  This causes problems for some distribution builds.
+
+v0.4.5 30-10-2014 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Added a Pigeonhole version banner to doveconf output. This way, future
+	  bug reports will also include Pigeonhole version information.
+	- Fixed handling of implicit keep. Last version erroneously reported that
+	  implicit keep succeeded after an earlier failure, while it in fact had
+	  failed. Particularly occurred for mailbox quota errors. 
+	- Fixed segfault occurring on SunOS systems when there is no active script.
+
+v0.4.4 28-10-2014 Stephan Bosch <stephan@rename-it.nl>
+
+	* Added support for Japanese mail addresses with dots at non-standard places
+	  in localpart.
+	* Changed handling of ENOSPACE into a normal temporary failure and added
+	  handling of ENOQUOTA as a user error.
+	* Restructured result execution, so that all actions which involve mail
+	  storage are always committed before all others.
+	+ Implemented support for generic Sieve storages. Using alternative storages
+	  now also possible for sieve_before/sieve_after.
+	+ Implemented storage driver for retrieving Sieve scripts from LDAP. This
+	  currently cannot be used with ManageSieve.
+	+ Implemented sieve_redirect_envelope_from setting, which allows configuring
+	  the envelope sender of redirected messages.
+	- Fixed handling of mail storage errors occurring while evaluating the input
+	  message.
+	- managesieve-login:
+	   - Removed bogus ALERT response code returned for AUTHENTICATE command.
+	   - Fixed handling of invalid initial response argument to AUTHENTICATE
+	     command.
+	- Fixed handling of stream errors in lexical scanner.
+	- Fixed handling of SMTP errors. Permanent and temporary errors were mixed up.
+	- Fixed several problems reported by CLang 3.4.
+	- duplicate extension: Fixed erroneous compile error about conflicting tags
+	  when `:handle' argument was used last.
+	- relational extension: Fixed error handling of `:value' match.
+	- editheader extension: Fixed header unfolding and header iteration.
+	- mailbox extension: Fixed the `:create' tag, which erroneously subscribed an
+	  existing folder.
+	- extprograms plugin: Fixed handling of error codes.
+	- doveadm-sieve plugin: Fixed several bugs. Synchronization of symbolic link
+	  in the file storage should now also work properly.
+
+v0.4.3 12-05-2014 Stephan Bosch <stephan@rename-it.nl>
+
+	* Editheader extension: Made control characters allowed for editheader, except
+	  NUL. Before, this would cause a runtime error.
+	+ Upgraded Dovecot-specific Sieve "vnd.dovecot.duplicate" extension to match
+	  the new draft "duplicate" extension.
+	- Fixed sieve_result_global_log_error to log only as i_info in administrator
+	  log (syslog) if executed from multiscript context.
+	- Sieve redirect extension: Adjusted loop detection to show leniency to resent
+	  messages.
+	- Sieve include extension: Fixed problem with handling of duplicate includes
+	  with different parameters :once or :optional.
+	- Sieve spamtest/virustest extensions: Tests were erroneously performed
+	  against the original message. When used together with extprograms filter to
+	  add the spam headers, the changes were not being used by the spamtest and
+	  virustest extensions. 
+	- Deprecated Sieve notify extension: Fixed segfault problems in message string
+	  substitution.
+	- ManageSieve: Fixed active link verification to handle redundant path slashes
+	  correctly.
+	- Sieve vacation extension:
+	  - Fixed interaction of sieve_vacation_dont_check_recipient with
+	    sieve_vacation_send_from_recipient setting.
+	  - Fixed log message for discarded response.
+	- Sieve extprograms plugin:
+	  - Forgot to disable the alarm() timeouts set for script execution.
+	  - Fixed fd leak and handling of output shutdown.
+	  - Fixed 'Bad filedescriptor' error occurring when disconnecting script
+	    client.
+	  - Made sure that programs are never forked with root privileges.
+
+v0.4.2 26-09-2013 Stephan Bosch <stephan@rename-it.nl>
+	
+	* Incompatible change in Sieve doveadm plugin: the root attribute for
+	  Sieve scripts is changed. Make sure that you update both sides of a dsync
+	  setup simultaneously when Sieve is involved, otherwise synchronization will
+	  likely fail.
+	+ Added support for sending Sieve vacation replies with an actual sender,
+	  rather than the default <> sender. Check the updated
+	  doc/extensions/vacation.txt for more information.
+	- Fixed a binary code read problem in the `set' command of the Sieve variables
+	  extension. Using the set command with a modifier and an empty string value
+	  would cause code corruption problems while running the script.
+	- Various fixes for doveadm-sieve plugin, mostly crashes. These include a fix
+	  for the `Invalid value for default sieve attribute' problem.
+	- Various fixes for compiler and static analyzer warnings, e.g. as reported
+	  by CLang and on 32 bit systems.
+	- Fixed the implementation of the new :options flag for the Sieve include
+	  extension.
+	- Fixed potential segfault bug at deinitialization of the lda-sieve plugin.
+	- Fixed messed up hex output for sieve-dump tool.
+
+v0.4.1 03-06-2013 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Added support for handling temporary failures. These are passed back to
+	  LDA/LTMP to produce an appropriate response towards the MTA. 
+	- Sieve storage: Removed PATH_MAX limitation for active symlink. This caused
+	  problems for GNU/Hurd.
+	- Fixed line endings in X-Sieve headers added by redirect command.
+	- ManageSieve: Fixed '[' ']' stupidity for response codes (only happened
+	  before login).
+	- Fixed setting name in example-config/conf.d/20-managesieve.conf.
+	- Sieve extprograms plugin: Fixed interaction between pipe command and remote
+	  script service. The output from the script service was never read, causing a
+	  broken pipe error at the script service. Apparently, this was broken since
+	  the I/O handling for extprograms was last revised. 
+	- Fixed assertion failure due to datastack problem in message header
+	  composition.
+
+v0.4.0 09-05-2013 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Added doveadm-sieve plugin that provides the possibility to synch Sieve
+	  scripts using doveadm sync along with the user's mailboxes.
+	+ Added the Sieve extprograms plugin to the main Pigeonhole package. It is
+	  still a plugin, but it is now included so that a separate compile is no
+	  longer necessary and distributors are likely to include it. The extprograms
+	  plugin provides Sieve language extensions that allows executing 
+	  (administrator-controlled) external programs for message delivery,
+	  message filtering and string manipulation. Refer to
+	  doc/plugins/sieve_extprograms.txt for more information.
+	+ Added debug message showing Pigeonhole version at initialization. Makes it
+	  very clear that the plugin is properly loaded.
+	+ Finished implementation of the Sieve include extension. It should now
+	  fully conform to RFC 6609. The main addition is the new :optional tag which
+	  makes the include command ignore missing included scripts without an error.
+	+ Finished implementation of the Sieve environment extension as much as
+	  possible. Environment items "location", "phase" and "domain" now also
+	  return a usable value.
+
+v0.3.6 26-09-2013 Stephan Bosch <stephan@rename-it.nl>
+
+	- Fixed a binary code read problem in the `set' command of the Sieve variables
+	  extension. Using the set command with a modifier and an empty string value
+	  would cause code corruption problems while running the script.
+	- Various fixes for compiler and static analyzer warnings, as reported
+	  by CLang.
+	- ManageSieve: Fixed '[' ']' stupidity for response codes (only happened
+	  before login).
+	- Fixed setting name in example-config/conf.d/20-managesieve.conf.
+	- Fixed messed up hex output for sieve-dump tool.
+
+v0.3.5 09-05-2013 Stephan Bosch <stephan@rename-it.nl>
+
+	- Sieve editheader extension: fixed interaction with the Sieve body extension.
+	  If used together, the deleteheader action could fail after a body test was
+	  performed.
+	- Test suite: fixed a time zone dependency in the Sieve date extension tests.
+
+v0.3.4 06-04-2013 Stephan Bosch <stephan@rename-it.nl>
+
+	* Changed error handling to be less of a nuisance for administrators. Strictly
+	  user-caused errors are only reported in user log. Some errors are logged as
+	  info instead.
+	* Sieve: Changed behavior of redirect in case of a duplicate message delivery
+	  or a mail loop. If a duplicate is detected the implicit keep is canceled,
+	  as though the redirect was successful. This prevents getting local
+	  deliveries. The original SMTP recipient is used when it is available to
+	  augment the entry in the LDA duplicate database. This way, duplicates are
+	  only detected when (initially) addressed to the same recipient.
+	+ Sieve vnd.dovecot.duplicate extension: added new features to the duplicate
+	  test, making it possible to manually compose the key value for duplicate
+	  checking. This extension is in the process of being standardized
+	  (https://tools.ietf.org/html/draft-bosch-sieve-duplicate-01).
+	+ Sieve date extension: generate warning when invalid date part is specified.
+	- Sieve editheader extension: fixed crash occurring when addheader :last was
+	  used.
+	- Sieve include extension: fixed missing error cleanup that caused a resource
+	  leak.
+	- Sieve vacation extension: fixed determination of From: address for when
+	  sieve_vacation_dont_check_recipient is active.
+	- Sieve tools: the -D option wasn't enabled and documented for all tools.
+	- Siev dict script storage: fixed potential segfault occurring when dict
+	  initialization fails.
+	- ManageSieve: fixed bug in skipping of CRLF at end of AUTHENTICATE command.
+	- ManageSieve: fixed handling of unkown commands pre-login.
+	- Fixed compile on Mageia Linux.
+
+v0.3.3 18-09-2012 Stephan Bosch <stephan@rename-it.nl>
+
+	- Fixed compile against installed Dovecot headers. This was broken by the
+	  ld.gold fix in the previous release.
+
+v0.3.2 18-09-2012 Stephan Bosch <stephan@rename-it.nl>
+
+	+ sieve-refilter tool: improved man page documentation by explicitly
+	  specifying the syntax used for mailbox arguments.
+	+ Sieve: spamtest and virustest extensions: improved trace debugging of score
+	  calculation.
+	+ Sieve: made error messages about exceeding the maximum number of actions
+	  more verbose.
+	- Sieve tools: fixed problems with running as root: sievec and sieve-dump now
+	  ignore mail_uid and mail_gid settings when run as root.
+	- Sieve: fixed bug in action accounting (for limit checking): increase action
+	  instance count only when an action is actually created.
+	- Sieve: include extension: fixed namespace separation of :global and
+	  :personal scripts.
+	- ManageSieve: fixed segfault bug triggered by CHECKSCRIPT command.
+	- Fixed linking with ld.gold.
+	- Fixed several Clang compile warnings and a few potential bugs.
+
+v0.3.1 25-05-2012 Stephan Bosch <stephan@rename-it.nl>
+
+	* Added support for retrieving Sieve scripts from dict lookup. This means that
+	  Sieve scripts can now be downloaded from a database. Compiled script
+	  binaries are still put on disk somewhere if used. The INSTALL documentation
+	  is updated with information on this new feature and the
+	  (backwards-compatible) changes to the configuration. Note that his feature
+	  is currently not supported for sieve_before/sieve_after or script management
+	  through ManageSieve.
+	+ Incorporated the sieve_duplicate plugin into main Pigeonhole tree as a
+	  normal extension (vnd.dovecot.duplicate). This Dovecot-specific extension
+	  adds the ability to check for duplicate deliveries based on message ID.
+	  Specification can be found in: doc/rfc/spec-bosch-sieve-duplicate.txt
+	+ Added support for specifying multiple sieve_before and sieve_after paths.
+	  This adds much more flexibility to the multiscript configuration. One
+	  application is to have user-specific Sieve scripts outside the user's
+	  normal control through ManageSieve.
+	+ Added a "session ID" string for managesieve connections, available in
+	  %{session} variable (analogous to Dovecot change).
+	- Fixed several small issues, including a few potential segfault bugs, based
+	  on static source code analysis.
+	- ManageSieve: changed use of EPROTO error to EIO in ManageSieve string stream
+	  implementation because it is apparently not known in BSD.
+	- Gave stamp.h.in (needed for autotools) some content to prevent it from
+	  disappearing in patch files.
+	- Fixed bug that caused a SunStudio CC compile failure (reported by Piotr
+	  Tarnowski).
+
+v0.3.0 16-02-2012 Stephan Bosch <stephan@rename-it.nl>
+
+	* Renamed sieve_global_path setting to sieve_default for clarity. Old name is
+	  still recognized for backwards compatibility. Support for the ancient (pre
+	  v1.1) name for this setting "global_script_path" is now dropped.
+	* Added means to prohibit use of redirect action. Setting sieve_max_redirects
+	  to 0 now means that redirect is disallowed instead of unlimited. Default
+	  value remains four.
+	* Fixed interaction of Sieve include extension with ManageSieve. It is updated
+	  to match new requirements in the draft include specification. Missing
+	  included scripts are no longer an error at upload time.
+	* Updated RFC2822 header field body verification to exclude non-printing
+	  characters (RFC5322). Only Sieve actions that can create unstructured header
+	  values (currently enotify/mailto and editheader) are affected by this
+	  change.
+	+ Completed sieve-filter tool to a useful state. The sieve-filter tool
+	  provides a means to (re)filter messages in a mailbox through a Sieve script.
+	+ Implemented the Sieve editheader extension. It is now possible to add and
+	  remove message headers from within Sieve.
+	+ ManageSieve: added support for reading quoted and literal strings as a
+	  stream. Fixes support for handing large SASL responses (analogous to similar
+	  changes in Dovecot). It is now also allowed to use a quoted string for the
+	  PUTSCRIPT script argument.
+	+ Added code to cleanup tmp directory in Sieve storage directory (sieve_dir)
+	  every once in a while.
+	+ Added support for substituting the entire message during Sieve processing.
+	  This is used for the filter action provided by the new sieve_extprograms
+	  plugin (provided separately for now). The filter action allows passing the
+	  message through an external program.
+	+ Added support for restricting certain Sieve language extensions to
+	  (admin-controled) global scripts. Restricted extensions can be configured
+	  using the new sieve_global_extensions setting. This is particularly useful
+	  for some of the Dovecot-specific (plugin-based) Sieve extensions, that can
+	  be somewhat hazardous when under direct control of users (e.g.
+	  sieve_extprograms).
+
+v0.2.6 13-02-2012 Stephan Bosch <stephan@rename-it.nl>
+
+	* This release fixes unintentional behavior of the include extension. Included
+	  scriptnames with a name like "name.sieve" would implicitly map to a script
+	  file called "name.sieve" and not "name.sieve.sieve". Keep in mind that the
+	  .sieve file extension has no meaning from within the Sieve language. A Sieve
+	  script is always stored with an appended .sieve file extension, also when
+	  the name already ends with a .sieve suffix.
+	  IMPORTANT: Some installations have relied on this unintentional feature, so
+	  check your script includes for issues before upgrading.
+	* Matched changes regarding auth_verbose setting in Dovecot. This means that
+	  this release will only compile against Dovecot v2.0.18.
+	- Fixed problem in ManageSieve that caused it to omit a WARNINGS response code
+	  when the uploaded script compiled with warnings.
+	- Made sure that locations of Sieve error never report `line 0'.
+	- Fixed potential segfault occurring when interpreter initialization fails.
+
+v0.2.5 19-11-2011 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Sieve vacation extension: made discard message for implicit delivery more
+	  verbose
+	- The sieve-test tool: mixed up original and final envelope recipient in
+	  implementation of command line arguments.
+	- Sieve vacation extension: resolved FIXME regarding the use of variables in
+	  the :handle argument. Variables are now handled correctly.
+	- Sieve body extension: fixed handling of :content "message/rfc822". This now
+	  yields the headers of the embedded message as required by the specification.
+		Handling of :content "multipart" remains to be fixed.
+	- LDA Sieve plugin: fixed problem with recipient_delimiter configuration. Now
+	  falls back to global recipient_delimiter setting if
+	  plugin/recipient_delimiter is not set.
+
+v0.2.4 13-09-2011 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Vacation extension: finally added support for using the original recipient
+	  in vacation address check. It is also possible to disable the recipient
+	  address check entirely. Check doc/vacation.txt for configuration
+	  information.
+	+ Include extension: made limits on the include depth and the total number of
+	  included scripts configurable. Check doc/include.txt for configuration
+	  information.
+	+ Implemented ihave extension. This allows checking for the availability
+	  of Sieve language extensions at 'runtime'. Actually, this is checked
+	  at compile time. At runtime the interpreter checks whether extensions
+	  that were not previously available are still unavailable. If the situation
+	  changed, the script is re-compiled and the ihave tests are evaluated again.
+	+ Sieve: optimized compilation of tests that yield constant results (i.e.
+	  known at compile tme), such as 'true' and 'false'. No code is produced
+	  anymore for script sections that are never executed. Also, semantics
+	  are not verified anymore in uncompiled script sections.
+	+ Made vnd.dovecot.debug extension available to the LDA plugin instead of
+	  only the command line tools.
+	+ Sieve: redirect action now adds X-Sieve-Redirected-From header (mainly for
+	  people using SPF/SRS).
+	- Sieve: fixed bug in handling flags and keywords; in case of error an
+	  assertion was triggered.
+	- Script storage: improved handling of unconfigured user home directory.
+	  Originally this would produce an unhelpful error message.
+	- Imap4flags extension: prevent forcibly enabling imap4flags when imapflags
+	  is enabled.
+	- Fixed various -Wunused-but-set-variable compiler warnings.
+	- Include extension: forgot to check variable identifier syntax for 'global'
+	  command.
+	- Sieve: fixed debug mode; no messages were logged in some situations.
+	- sievec tool: forgot to enable -D (debug) parameter.
+
+v0.2.3 14-04-2011 Stephan Bosch <stephan@rename-it.nl>
+
+	* Sieve filter tool: finished implementing basic functionality. It is not
+	  quite ready yet, but it is available for those willing to experiment
+	  with it (needs --with-unfinished-features config to compile). Also
+	  includes man page.
+	+ Vacation extension now inhibits replies to messages from sender listed
+	  in :addresses, thus preventing replies to one of the user's other known
+	  addresses.
+	+ Vacation extension: implemented the (draft) vacation-seconds extension.
+	  This also adds min/max period configuration settings. Refer to
+	  doc/vacation.txt for configuration information.
+	- ManageSieve: fixed bug in UTF-8 checking of string values. This is done
+	  by discarding the original implementation and migrating to the Dovecot
+	  API's UTF-8 functionality.
+	- Sieve command line tools now avoid initializing the mail store unless
+	  necessary. This prevents sievec and sieve-dump from failing when
+	  executed by root for example.
+	- Enotify extension: fixed inappropriate return type in mailto URI parse
+	  function, also fixing ARM compiler warning.
+	- Vacation extension: fixed handling of sendmail errors. It produced an
+	  additional confusing success message in case of error.
+	- Removed header MIME-decoding to fix erroneous address parsing. Applies to
+	  address test and vacation command.
+	- Fixed segfault bug in extension configuration, triggered when unknown
+	  extension is mentioned in sieve_extensions setting.
+
+v0.2.2 06-12-2010 Stephan Bosch <stephan@rename-it.nl>
+
+	* LDA Sieve plugin: started using Dovecot LDA reject API for the reject
+	  extension. This means that the LDA reject_reason and reject_subject
+	  settings now also work for Pigeonhole's LDA Sieve plugin.
+	* Did some work on the new sieve-filter tool. It is mostly functional, but
+	  it is not finished yet.
+	* Dovecot change: services' default vsz_limits weren't being enforced
+	  correctly in earlier v2.0 releases. Now that they are enforced, you might
+	  notice that the default limits are too low and you need to increase them.
+	  This problem will show up in logs as "out of memory" errors. See
+	  default_vsz_limit and service { vsz_limit } settings.
+	- Imap4flags: fixed segfault bug occurring in multiscript context.
+	- Added version checking to the ManageSieve settings plugin. This plugin was
+	  forgotten when the LDA plugin was updated with this change in the previous
+	  release.
+	- LDA Sieve plugin: fixed memory leak at deinitialization.
+
+v0.2.1 27-09-2010 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Incorporated distinction between original and final envelope recipient in
+	  Sieve interpreter, as recently introduced in Dovecot.
+	+ Regex extension: added support for regex keys composed from variables.
+	- LDA Sieve plugin: added _version symbol to enable Dovecot's plugin version
+	  check. Without this check, people can forget to recompile the plugin, which
+	  can lead to unexpected effects.
+	- LDA Sieve plugin: turned debug message about an unconfigured home directory
+	  into a proper error and added script path information.
+	- Fixed unnecessary reporting of dummy extensions in ManageSieve SIEVE
+	  capability; the comparator-i;octet and comparator-i;ascii-numeric
+	  'extensions' were reported explicitly.
+
+v0.2.0 10-09-2010 Stephan Bosch <stephan@rename-it.nl>
+
+	* Merged Sieve and ManageSieve packages into a single Pigeonhole package.
+	  There is also no need to patch Dovecot anymore to gain ManageSieve support.
+	  Version numbering of previous Sieve releases is continued as v0.2.0. The
+	  sources originally branched off from Sieve v0.1.5 and ManageSieve v0.11.4,
+	  but the NEWS history of much more recent releases for Dovecot v1.2 is
+	  included since these changes are all included in this release as well.
+	* The ManageSieve service now binds to TCP port 4190 by default due to the
+	  IANA port assignment for the ManageSieve service. When upgrading from v1.2,
+	  this should be taken into account. The service can be configured manually to
+	  listen on both 2000 and 4190.
+	* The Dovecot configuration now calls the ManageSieve protocol 'sieve' in
+	  stead of 'managesieve' because it is registered as such with IANA. The
+	  binaries and the services are still called managesieve and
+	  managesieve-login.
+	* The binary representation of a compiled Sieve script is updated to include
+	  source code locations of all commands and arguments. This is implemented in
+	  a similar manner as such debug information is included in some system
+	  executables and libraries (DWARF-like). Run-time errors can now always refer
+	  to the proper line number in the Sieve source script.
+	* The Sieve plugin is adapted to work properly with the new LMTP service
+	  introduced with Dovecot v2.0. The same plugin is used for both LDA and LMTP.
+	* The 'sieve_subaddress_sep' setting for the Sieve subaddress extension is now
+	  known as 'recipient_delimiter'. Although the deprecated sieve_subaddress_sep
+	  setting is still recognized for backwards compatibility, it is recommended
+	  to update the setting to the new name, since the new LMTP service also uses
+	  the recipient_delimiter setting.
+	* ManageSieve: changed default IMPLEMENTATION capability to from 'Dovecot' to
+	  'Dovecot Pigeonhole'.
+	* Renamed the sieved tool to sieve-dump. The original name was somewhat
+	  confusing.
+	* Updated man pages to match style and structure of new Dovecot man pages.
+	* Made testsuite commands more uniform and cleaned up many of the testsuite
+	  scripts. Some minor new tests were added in the process.
+	+ Simplified string matching API to use abstract string lists as data sources.
+	  This will also make implementing the index extension easier in the future.
+	+ Significantly improved trace debugging with the sieve-test tool. The full
+	  execution of the script can be examined, including the matched values and
+	  keys of the respective Sieve test commands. The executed statements are
+	  listed with their line number (and code address when requested). The level
+	  of detail is configurable from the command line.
+	+ The SIEVE and NOTIFY capabilities reported by the ManageSieve protocol can
+	  now be configured manually. If left unconfigured, the capabilities are
+	  determined from the default Sieve and ManageSieve configuration.
+	  User-specific capabilities aren't reported until after authentication.
+	+ Significantly improved file error handling. This means that administrators
+	  get a more useful and informative log message when file operations fail. The
+	  most notable example is that when the LDA Sieve plugin is trying to store a
+	  binary for a global script, the resulting failure message also points the
+	  administrator towards pre-compiling the script with sievec.
+	+ Added runtime argument value checking for several commands (redirect, date
+	  vacation). When variables are used, these checks cannot be performed at
+	  compiletime. A proper runtime error now is produced when invalid data is
+	  encountered.
+	+ UTF8 validity of fileinto command argument is now checked either at compile
+	  time or at runtime. Previously, it was not checked until the store action
+	  was executed.
+	+ Validity of IMAP flags for the imap4flags extension is now checked also
+	  at runtime. Previously, it was not checked until the store action was
+	  executed.
+	+ Simplified and restructured error handling. Also made sure that user-caused
+	  errors are no longer written to the Dovecot master/LDA log.
+	- Multiscript: fixed duplicate implicit keep caused by erroneous execution
+	  state update.
+	- Prevented assertion failure due to currupt binary string representation.
+	  If the string was missing a final \0 character an assertion was produced in
+	  stead of a binary corruption error.
+	- Imap4flags: fixed bug in setflag command; when parameter was a stringlist,
+	  only the last item was actually set.
+	- Variables extension: fixed :length set modifier to recognize utf8 characters
+	  instead of octets.
+	- Testsuite: prevented innocent warning messages, i.e. those that are part of
+	  the test, from showing up by default.
+	- ManageSieve/Sieve storage: fixed error handling of PUTSCRIPT commmand; save
+	  commit errors would not make the command fail.
+	- ManageSieve: enforced protocol syntax better with some of the commands; some
+	  commands allowed spurious extra arguments.
+	- Fixed Sieve script name checking to properly handle length limit and added
+	  0x00ff as invalid character.
+	- Removed spurious old stdio.h (top) includes; these caused compile issues on
+	  specific systems.
+	- Fixed default Sieve capability (as reported by ManageSieve): extra
+	  extensions spamtest, spamtestplus and virustest were enabled by default.
+	  These should, however, only be enabled when properly configured and there
+	  is no default configuration.
+
+(Fused Dovecot Sieve and ManageSieve packages into a single Pigeonhole release)
+
+Dovecot Sieve NEWS history:
+---------------------------
+
+Dovecot 1.2:
+
+v0.1.17 19-06-2010 Stephan Bosch <stephan@rename-it.nl>
+
+	- Made sure source code positions for compiler messages are recorded at start
+	  of tokens.
+	- Fixed a few potential memory leaks in the Sieve compiler and the
+	  spam/virustest extensions.
+	- Made command line tools return proper exit status upon failure.
+
+v0.1.16 30-04-2010 Stephan Bosch <stephan@rename-it.nl>
+
+	* Finished implementation of spamtest, spamtestplus and virustest extensions.
+	  These are not enabled by default and need to be activated with the
+	  sieve_extensions setting. Documentation available in
+	  doc/spamtest-virustest.txt
+	+ Vacation extension: the from address of the generated reply is now by
+	  default equal to whatever known recipient alias matched the headers of the
+	  message. If it is one of the aliases specified with :addresses, it is used
+	  instead of the envelope recipient address that was used before.
+	+ Restructured and optimized the lexical scanner.
+	+ Added --with-docs configure option to allow disabling installation of
+	  documentation.
+	- Accidentally omitted 'extern' in two declarations of global variables in
+	  header files, causing compile failures on certain systems.
+	- Deprecated imapflags extension: fixed implicit assignment of flags. Turns
+	  out this never really worked, but the effect of this bug was obscured by the
+	  removeflag bug fixed in the previous release.
+	- Fixed various memset argument mixups in enotify extension. This caused
+	  warnings on certain systems, but luckily no adverse effects at runtime.
+
+v0.1.15 25-01-2010 Stephan Bosch <stephan@rename-it.nl>
+
+	* Enotify extension:
+	  - Adjusted notify method API for addition of new notification methods.
+	  - Set default importance level to 'normal' (was 'high').
+	* Include extension: updated implementation towards most recent specification
+	  (all should be backwards compatible):
+	  - Implemented global variables namespace.
+	  - Global command may now appear anywhere in a script.
+	  - Implemented script name checking using the requirements specified in the
+	    ManageSieve draft.
+	  - One issue remains: ManageSieve currently requires included scripts to be
+	    uploaded first, which is not according to specification.
+	* Changed envelope path parser to allow to and from envelope addresses that
+	  have no domain part.
+	+ Added preliminary support for Sieve plugins and added support for installing
+	  Sieve development headers.
+	+ Started work on the implementation of the spamtest, spamtestplus and
+	  virustest extensions (unfinished).
+	+ Deprecated notify extension: implemented denotify command.
+	+ Variables extension: added support for variable namespaces.
+	+ Added configurable script size limit. Compiler will refuse to compile files
+	  larger than sieve_max_script_size.
+	+ Testsuite changes:
+	  - Added support for changing and testing an extension's configuration.
+	  - Added a command line parameter for copying errors to stderr.
+	- Fixed a bug in the i;ascii-numeric comparator. If one of the strings started
+	  with a non-digit character, the comparator would always yield less-than.
+	- Imap4flags extension: fixed bug in removeflag: removing a single flag failed
+	  due to off-by-one error (bug report by Julian Cowley).
+	- Improved EACCES error messages for stat() and lstat() syscalls and slightly
+	  improved error messages that may uccur when saving a binary.
+	- Vacation extension: fixed typo in runtime log message (patch by Julian
+	  Cowley).
+	- Fixed use of minus '-' in man pages; it is now properly escaped.
+	- Fixed parser recovery. In particular cases it would trigger spurious errors
+	  after an initial valid error and sometimes additional errors were
+	  inappropriately ignored.
+
+v0.1.14 19-12-2009 Stephan Bosch <stephan@rename-it.nl>
+
+	* Made the imposed limits on the number of redirects and the number of
+	  actions configurable. The settings are called sieve_max_actions and
+	  sieve_max_redirects.
+	* Did a major rework of extension handling, making sure that no global state
+	  is maintained. This change was triggered by problems that global state info
+	  would cause for Dovecot v2.0, but it is also important for v1.2 as it
+	  significantly cleans up the library implementation.
+	+ Made LDA Sieve plugin recognize the deliver_log_format setting.
+	+ Message headers produced from user-supplied data are now RFC2047-encoded if
+	  necessary for outgoing messages. This is for example important for the
+	  :subject argument of the vacation action.
+	+ Added support for the $text$ substitution in the deprecated notify
+	  extension.
+	+ The subaddress extension now also accepts recipient_delimiter setting as an
+	  alias for sieve_subaddress_sep setting. This anticipates the
+	  recipient_delimiter setting in v2.0.
+	- Fixed logging of mailbox names. It logged the converted mUTF7 version in
+	  stead of the original UTF8 version supplied by the user.
+	- Fixed a minor memory leak in the multiscript support.
+	- Fixed a bug in the recompilation of Sieve scripts. Made sure that scripts
+	  are only recompiled when the script file - or the symlink pointing to it -
+	  is strictly newer.
+
+v0.1.13 18-10-2009 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Body extension: implemented proper handling of the :raw transform and added
+	  various new tests to the test suite. However, :content "multipart" and
+	  :content "message/rfc822" are still not working.
+	+ Fixed race condition occurring when multiple instances are saving the same
+	  binary (patch by Timo Sirainen).
+	+ Test suite: added support for testing multiscript execution.
+	- Made compiler more lenient towars missing CRLF at the end of the script in a
+	  hash comment.
+	- Body extension: don't give SKIP_BODY_BLOCK flag to message parser, we want
+	  the body! (patch by Timo Sirainen).
+	- Fixed handling of implicit side effects for multiscript execution.
+	- Fixed bugs in multiscript support; subsequent keep actions were not always
+	  merged correctly and implicit side effects were not always handled
+	  correctly.
+	- Fixed a segfault bug in the sieve-test tool occurring when compile fails.
+	- Fixed segfault bug in action procesing. It was triggered while merging side
+	  effects in duplicate actions.
+	- Fixed bug in the Sieve plugin that caused it to try to stat() a NULL path,
+	  yielding a 'Bad address' error.
+
+v0.1.12 21-08-2009 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Testsuite: added support for testing binaries stored on disk.
+	+ Implemented the new date extension. This allows matching against date values
+	  in header fields and the current date at the time of script evaluation.
+
+v0.1.11 08-08-2009 Stephan Bosch <stephan@rename-it.nl>
+
+	+ Built skeleton implementation for the date extension (RFC 5260). It
+	  compiles, but it does not do anything useful yet. Therefore, it is not part
+	  of the default compilation.
+	- Fixed ARM portability issues caused by char type not being signed on that
+	  platform. Reading optional operands from a binary would fail for action side
+	  effects. Also, an accidental mixup of an int return type with bool caused
+	  the interpreter to continue on ARM even though an error occured.
+	- Removed direct stdint.h includes to prevent portability issues.
+	- Fixed segfault bug in the handling of script open failures.
+	- Include: improved user error messages and system log messages.
+	- Fixed copy-paste mixup between sieve_after and sieve_before settings in the
+	  LDA Sieve plugin. If only a sieve_after script was active, nothing would
+	  have been executed. Patch by Mike Abbott.
+	- Include: fixed a bug in HOME substitution in the sieve_dir path. Surfaced in
+	  ManageSieve.
+
+v0.1.10 03-08-2009 Stephan Bosch <stephan@rename-it.nl>
+
+	* Changed action execution of fileinto and keep. These changes depend on API
+	  additions in Dovecot, making this release depend on Dovecot v1.2.2 or newer.
+	* Further developed the sieve-filter command line tool. This required a few
+	  changes to the action execution of the Sieve engine. The tool was
+	  successfully tested on folders with a few 100k spam messages. However, the
+	  commandline options are still incomplete, a man page is missing and it needs
+	  much more testing before I can recommend anyone to use this tool.
+	+ Added support for the mailbox extension. This allows checking whether a
+	  mailbox exists using the mailboxexists command and it adds the :create
+	  argument to the fileinto command to create the mailbox when it is missing.
+	  The :create feature is useless unless the Deliver LDA is run with the -n
+	  option.
+	+ Improved the testsuite with tests for message delivery. Messages stored
+	  using keep and fileinto can be fed back into the Sieve engine for
+	  verification. This includes testing of applied IMAP flags.
+	+ Updated the man pages with the new method of specifying the supported
+	  extensions using + and - (for the -x parameter of the sieve tools)
+	+ Further developed the deprecated notify extension. A dummy for the denotify
+	  command exists, meaning that its use does not cause an error anymore.
+	- Fixed a bug in the derivation of the binary path from the script path. A
+	  bare filename would yield a path relative to root.
+	- Fixed a bug in the value matching code. The context data now uses a proper
+	  pool instead of the data stack. Bug reported by Jan Sechser.
+	- Fixed assertion fail in the include extension caused by missing
+	  initialization upon binary load. This bug surfaces only for stored
+	  binaries. Bug reported by Tom Hendrikx.
+	- Fixed include error message for failed :global include. It mentioned the
+	  wrong config parameter.
+	- Fixed broken wiki reference in an error message of the plugin about the
+	  'sieve' setting.
+	- Fixed behavior of fileinto when delivering into a namespace prefix.
+	  Previous fix used the wrong storage.
+
+v0.1.9 22-07-2009  Stephan Bosch <stephan@rename-it.nl>
+
+	* Removed the unfinished sieve-filter tool from the default build. It is now
+	  only built when the --with-unfinished-features switch is supplied during
+	  configure.
+	+ Started building support for the ereject version of the reject action,
+	  which has a preference to use an SMTP/LMTP protocol error instead of a
+	  bounce message. This is to be used to make the Sieve plugin honour Deliver's
+	  -e parameter. This is not yet finished and not built by default.
+	+ Improved 'Permission denied' error messages just like Dovecot does,
+	  precisely specifying what permission is missing to access or create a file.
+	+ Added additional headers to the list of allowed headers for the address
+	  test. The restrictive nature of the address test is not always appropriate.
+	  Still thinking of a better, less restrictive implementation.
+	+ Made the deprecated notify extension compatible with the old CMUSieve
+	  plugin. However, the denotify command and the $text$ substitution are not
+	  yet supported.
+	+ Made the discard action log a message to avoid confusion about disappearing
+	  messages.
+	- Fixed behavior of fileinto when delivering into a namespace prefix. It now
+	  uses silent delivery into INBOX as fallback.
+	- Fixed logging of folder namespace prefix upon delivery into a prefixed
+	  namespace. Formerly it only logged the bare folder name.
+	- Fixed a potential segfault in the argument validation. It didn't surface
+	  because no command could have a :tag followed by an associated parameter as
+	  last argument.
+	- Fixed segfault bug occurring in envelope test when performed on null (<>)
+	  envelope path. The fix involves a rather large restructuring of the code to
+	  make sure envelope addresses are properly handled everywhere (bug reported
+	  by Nikita Koshikov)
+	- Envelope: fixed bug in application of address parts; failure to obtain
+	  the part would cause inappropriate match success (bug reported by Ron Lee)
+	- Fixed extension conflict checks during validation. It could sometimes
+	  produce useless errormessages. This is currently only used by the
+	  deprecated extensions.
+	- Forgot to remove old explicit storage library dependency (patch by
+	  Arkadiusz Miskiewicz).
+	- Fixed compiler warnings on certain platforms regarding the use fwrite for
+	  outgoing message construction
+
+v0.1.8 12-07-2009  Stephan Bosch <stephan@rename-it.nl>
+
+	- Fixed AIX compile problem. For portability, the typeof operator is
+	  not used anymore.
+	+ Added partial support for the deprecated notify extension. However, it
+	  turns out that the implementation provided by cmusieve is even older (2001),
+	  meaning that this is currently not backwards compatible with cmusieve.
+
+v0.1.7 05-07-2009  Stephan Bosch <stephan@rename-it.nl>
+
+	+ Added support for CRLF line breaks in strbuf error handler to fix a
+	  ManageSieve problem.
+	+ Improved consistency of sieve tool documentation and fixed missing
+	  parameters in internal tool help output.
+	+ Enhanced extensions configuration, allowing to specify the enabled
+	  extensions relatively to the default (patch by Steffen Kaiser).
+	- Forgot to initialize script execution status in Sieve plugin, causing
+	  segfaults on compile errors in specific conditions.
+	- Fixed logging in Sieve plugin for execution of default main script (went
+	  to STDERR).
+
+v0.1.6 18-06-2009  Stephan Bosch <stephan@rename-it.nl>
+
+	* Adjusted to changes in Dovecot to make it compile against v1.2.rc5
+	* Made default of sieve_dir setting match the ManageSieve implementation.
+	- Fixed a few problems in de body extension that caused assert failures in
+	  specific situations.
+
+v0.1.5 18-04-2009  Stephan Bosch <stephan@rename-it.nl>
+
+	* Ported the implementation of the Sieve include extension to the latest
+	  draft. This means that the import and export commands are replaced by a new
+	  command called global. The import and export commands are now DEPRICATED and
+	  are mere aliases for the global command. The new specification also adds the
+	  :once modifier to the include command. The also newly specified global.*
+	  variable namespace is not implemented yet as support for variable namespaces
+	  is currently missing.
+	* Did a major rework of the multiscript support for better error handling and
+	  made sure that persistent global scripts (sieve_before/sieve_after) are
+	  always executed, even when the user does not have a script of his own and
+	  a global default is missing.
+	+ Provided basic support for the environment extension. Currenly, the name,
+	  version and host items are useful. Others are pending.
+	+ Improved error message that is presented when an unknown Sieve extension is
+	  provided as argument to the require command. It now notifies the user that
+	  Sieve core commands do not need to be specified in require.
+	- Fixed bug in includes at levels deeper than one.
+	- Fixed bug in address matching that was caused by the failure to handle group
+	  specifications. In dovecot, these are marked by address items with NULL
+	  elements, which causes a segfault if not considered. The group 'undisclosed-
+	  recipients:;' in particular triggered this bug. Bug reported by Bernhard
+	  Schmidt.
+
+v0.1.4 21-03-2009  Stephan Bosch <stephan@rename-it.nl>
+
+	* Started work on the sieve-filter tool. With this command line tool it will
+	  be possible to (re-)apply Sieve filters on a mail folder. It is currently
+	  undocumented and far from functional.
+	+ Added a custom debug extension that provides the possibility to print debug
+	  messages from scripts executed by the Sieve tools.
+	- Fixed issue with opening relative paths as a mail file. Bug reported by Ian
+	  P. Christian.
+	- Fixed MAC OSX compile problem. Turns out the extern modifier was missing at
+	  multiple places. Bug reported by Edgar Fuss.
+	- Fixed Solaris compile problem: removed unecessary and unportable linker
+	  flags that caused compile to fail. Bug reported by Andrés Yacopino.
+
+v0.1.3 12-02-2009  Stephan Bosch <stephan@rename-it.nl>
+
+	* Adapted to changes in Dovecot, making this release dependent on Dovecot
+	  >= 1.2.beta1
+	* Made mail address comparison fully case-insensitive. This is particularly
+	  noticeable for the :addresses argument of the vacation command.
+	+ Finished enotify extension. Currently, only the mailto notification method
+	  is implemented. All still needs to be tested thoroughly.
+	+ Implemented multiscript support. It is now possible to execute multiple
+	  Sieve scripts sequentially. Administrator-controlled scripts can be
+	  executed before and after the user's script. Still needs to be tested
+	  thoroughly.
+	+ Implemented support for configuring the available Sieve extensions.
+	+ Made the subaddress extension (partially) configurable using the
+	  sieve_subaddress_sep setting, which allows specifying a (multi-charater)
+	  separator other than '+'.
+	+ Compiler now warns about invalid header field names used for the header and
+	  address tests.
+	+ Vacation extension now properly generates a References header for the
+	  response message.
+	+ Added testing of basic result execution to the test suite. Also added
+	  supportfor testing the outgoing messages produced by the Sieve interpreter.
+	+ Included execution of the actual result in the sieve-test command line tool.
+	  The undocumented sieve-exec tool that existed for this is now removed as
+	  planned.
+	+ Added support for the now obsolete 'imapflags' extension for backwards
+	  compatibility with CMUSieve. This also implements the mark/unmark commands.
+	- Fixed bugs in the regex extension: 1) if an optional match value did not in
+	  fact match, subsequent match values would get unexpected indexes. 2) fixed
+	  segfault bug occurring when regex is freed.
+	- Fixed bug in the use of the :from agrument for the vacation command. If this
+	  address included a phrase part, the response would not be a valid RFC822
+	  message.
+	- Plugged a theoretical security hole occurring when a directory is opened as a
+	  Sieve binary.
+	- Cleaned up and fixed various log messages.
+	- Fixed bug in the outgoing address verification. Addresses ending in ',' were
+	  erroneously accepted.
+
+v0.1.2 26-11-2008  Stephan Bosch <stephan@rename-it.nl>
+
+	- Fixed important bug in the redirect action (and probably other actions like
+	  reject and vacation that only send messages). This was a bug in the handling
+	  of context information during the execution of actions. It caused the sieve
+	  interpreter to crash with a segfault when redirect was executed.
+
+v0.1.1 24-11-2008  Stephan Bosch <stephan@rename-it.nl>
+
+	* Re-enabled support for compiling against dovecot headers. Much like
+	  cmusieve, command line tools like sievec and sieved are not compiled in this
+	  case.
+	* Started implementation of enotify extension. Not anywhere near finished
+	  though.
+	* Adapted to changes in Dovecot on various occasions, making this release
+	  dependent on Dovecot >= v1.2.alpa4.
+	+ Improved logging of errors at specific occasions and added debug messages to
+	  find script execution problems quicker.
+	+ Removed code duplication between command line tools and the test suite.
+	  Also restructured the sources of the tools.
+	+ Added UTF-8 to UTF-7 folder name conversion for compatibility with IMAP.
+	+ Created man pages for the command line tools. These are automatically
+	  installed upon 'make install'
+	+ Incorporated Valgrind support into the testsuite and fixed a few memory
+	  leaks in the process.
+	- Fixed compile error surfacing for gcc3.4. Forgot mask argument for the
+	  open() system call when the O_CREAT flag is specified. Bug found by
+	  Sergey Ivanov.
+	- Fixed bug in the sievec tool. -d output was always written to stdout.
+	- Fixed important bug in the imap4flags extension. When no :flags argument is
+	  specified, the previous version would always use the final value of the
+	  internal variable to set the flags. This means that modifications to the
+	  internal variable also affected the bare fileinto/keep actions executed
+	  earlier. This does not comply to the RFC.
+	- Fixed bug in the include extension's import/export commands. Duplicate
+	  import/exports caused problems.
+	- Fixed bug in the handling of non-existent scripts. Errors were sometimes
+	  ignored.
+	- Dovecot omitted unfolding multi-line headers. This was added to the cmusieve
+	  plugin after the code was incorporated into the new implementation. This is
+	  now mplicitly fixed by concurrent change in Dovecot.
+
+v0.1.0 23-10-2008  Stephan Bosch <stephan@rename-it.nl>
+
+	* Initial release
+
+Dovecot ManageSieve NEWS history:
+---------------------------------
+
+Dovecot 1.2:
+
+v0.11.11:
+	* This release contains adjustments to match changes in the Sieve API. This
+	  means that this release will only compile against Pigeonhole Sieve
+	  v0.1.15.
+	+ Implemented ManageSieve QUOTA enforcement.
+	+ Added MAXREDIRECTS capability after login.
+	+ Implemented new script name rules specified in most recent ManageSieve
+	  draft.
+	- Fixed assertion failure occurring with challenge-response SASL mechanisms.
+	- Made configure complain about trying to compile against installed Dovecot
+	  headers alone.
+	- Fixed compile warning for compilation against CMUSieve.
+
+v0.11.10:
+	* This release contains adjustments to match changes in the Sieve API. This
+	  means that this release will only compile against Pigeonhole Sieve
+	  v0.1.14.
+	- Fixed compilation of ManageSieve against CMUSieve.
+
+v0.11.9:
+	* Adjusted to changes in the Dovecot login proxy API. This release
+	  therefore depends on Dovecot v1.2.4.
+	+ Reintroduced ability to abort SASL with "*" response. Latest ManageSieve
+	  specification includes it.
+
+v0.11.8:
+	- Fixed TLS support for proxying ManageSieve. The protocol state machine
+	  was incorrect. Also added a check that disables ssl when 'starttls' is
+	  not enabled for the user. This produces a proper warning in the log file.
+	  There is no such thing as a managesieveS protocol which has SSL from the
+	  start.
+
+v0.11.7:
+	* Adjusted to changes in the Dovecot login API. This release now depends on
+	  Dovecot v1.2.1 or newer.
+	* Incorporated various small changes in IMAP into ManageSieve. This includes
+	  properly enabling the generation of core dumps.
+	- The previous release implicitly resolved the FreeBSD script truncation
+	  error. This release adds a small correction to the code that detects the
+	  truncation.
+	- Fixed panic occurring when many errors are produced by the Sieve compiler
+	  (bug found by Pascal Volk).
+	- Fixed memory leak in the PUTSCRIPT command.
+
+v0.11.6:
+	* Adjusted to changes in Dovecot regarding client idle timeout vs
+	  authentication timeout. This release now depends on Dovecot v1.2.rc6 or
+	  newer.
+	- Fixed CRLF line breaks in compile errors (bug reported by Pascal Volk).
+	- Corrected directory/file creation behavior with respect to mode bits
+	  and gid (bug reported by Pascal Volk).
+	- Improved handling of script truncation bugs: connection is now closed and
+	  an error is logged. bug itself not fixed yet).
+	- Prevented temp script name from showing up in error output.
+
+v0.11.5:
+	* Incorporated various changes from imap-login into managesieve-login. This
+	  includes changes in the proxy support.
+
+v0.11.4:
+	* Adjusted to changes in the Dovecot signal handler API.
+
+v0.11.3:
+	* Changed the SASL service name from "managesieve" into "sieve" as required
+	  in the protocol specification. Don't forget to adjust your configuration
+	  if your authentication mechanism depends on this service name.
+	* Adapted to changes in Dovecot, making this release dependent on Dovecot
+	  >= v1.2.beta1.
+	* Adapted to changes in the new Sieve implementation, making this release
+	  dependent on Dovecot Sieve >= v0.1.3 if used. The old cmusieve plugin is
+	  still supported.
+	+ Implemented making the SIEVE and NOTIFY capability fully dynamic, meaning
+	  that the sieve_extensions setting that was introduced for the new Sieve
+	  plugin properly affects the ManageSieve daemon as well.
+	+ Added support for the CHECKSCRIPT command. In terms of the supported
+	  commands, the ManageSieve daemon now complies with protocol VERSION 1.0 as
+	  listed in the CAPABILITY response.
+	- Fixed maximum permissions for uploaded scripts; was 0777. This
+	  was shielded however by the default umask (not documented to be
+	  configurable), so the actual permissions would never have been 0777.
+	- Fixed a segfault bug in the authentication time-out. Bug report and trace
+	  provided by Wolfgang Friebel.
+	- Fixed handling of ~/ in use of mail-data for script location.
+	- Fixed small problems in the login proxy support.
+
+v0.11.2:
+	* Adapted to changes in Dovecot, making this release dependent on Dovecot
+	  >= v1.2.alpa4.
+
+v0.11.1:
+	- Fixed security issue that gives virtual users the ability to read and
+	  modify each other's scripts if the directory structure of the sieve
+	  storage is known.
+	* Updated NOOP command to match new protocol specification
+	+ Improved error handling and implemented the new response codes:
+	  ACTIVE, NONEXISTENT, ALREADYEXISTS and WARNINGS
+
+v0.11.0:
+	* Upgraded to Dovecot v1.2
+	* Added support for new ManageSieve extensions RENAME and NOOP
+	* Moved sieve settings to plugin {} section of config file. Now the settings
+	  `sieve` and `sieve_dir` in the plugin section are used for the Sieve plugin
+	  and the ManageSieve service, avoiding the posibility of accidental
+	  differences in configuration.
+
+Dovecot 1.1:
+
+v0.10.3
+	* Removed erroneous inline declarations that caused compiler warnings. GCC 4.3
+	  turns out to fail entirely as reported by Joel Johnson.
+	* Fixed auto-dectection of Sieve implementation during ./configure. It now
+	  produces a proper error when the directory is invalid.
+
+v0.10.2
+	* Fixed bug that caused SASL mechanisms that require more than a single client
+	  response to fail. Reported by Steffen Kaiser and occured when he tried using
+	  the (obsolete) LOGIN mechanism.
+	* Updated installation and configuration documentation to match the
+	  information provided in the wiki
+
+v0.10.1
+	* Fixed bug introduced in v0.10.0: compiled scripts were also written to disk
+	  in the sieve/tmp directory and left there. This accumulates much .sievec
+	  junk in that directory over time.
+	* Fixed bug in tmp file generation for sieve-storage: errors other than EEXIST
+	  would cause the daemon to sleep() loop indefinitely.
+
+	+ Improved log lines to be more recognizable as being generated from
+	  managesieve.
+	+ Added short proxy configuration explanation to the README file
+	+ Added 'Known Issues' section to the README file
+	- Fixed assert bug in sieve-storage occurring when save is canceled.
+
+v0.10.0
+	* Upgraded to Dovecot 1.1:
+		- The actual managesieve implementation is now a separate package.
+		  The dovecot tree still needs to be patched though to make dovecot
+		  recognize the new managesieve service.
+		- Incorporated changes to imap/imap-login into the equivalent
+		  managesieve processes.
+		- Removed cmusieve implementation from managesieve sources. It is
+		  now linked externally from the dovecot-sieve-1.1 package.
+		- Restructured README.managesieve file into separate README, NEWS,
+		  TODO, DESIGN and INSTALL files.
+	* Added support for new libsieve implementation (to be released). This
+	  package can be compiled with either the new or the old Sieve
+	  implementation (autodetected). If the new Sieve becomes stable, this
+	  package will be merged with it to make a single package for Dovecot
+	  Sieve support.
+
+Dovecot 1.0:
+
+v9
+
++ Definitively fixed the segfault mentioned in V8. It proved to be
+  very time-constrained and thus hard to reproduce. The error turned out
+  to be related to the input handling of the login daemon during
+  authentication.
++ Checked for changes in the imap daemon that weren't propagated to the
+  managesieve implementation due to code duplication.
++ Fixed a bug in the autodetection of the sieve storage location.
++ Fixed bug in the sieve storage that failed to refresh the symlink if
+  the storage was moved.
++ Improved error handing in the sieve-storage implementation in various
+  places.
++ Fixed the situation in which the active script link is located in the
+  sieve storage.
++ Added managesieve configuration to dovecot-example.conf and made the example
+  in this file more concise.
+
+v8
+
++ Fixed a few incompatibilities with 1.0.7 version. For instance, the "Logged
+  in" message is now sent by the -login process and not by the managesieve
+  daemon anymore. This caused a segfault every once in a while.
++ Probably fixed the settings problem reported by Steffen Kaiser regarding
+  login_dir. 'dovecot -n' now reports correct results, but testing will show
+  whether the whole problem is solved.
++ The managesieve daemon now accepts the sieve_storage and sieve configuration
+  settings, so it is now possible to explicitly configure the location of the
+  sieve storage and the active script respectively. The daemon still falls back
+  to using the mail_location (MAIL) settings if nothing else is specified.
++ The cyrus timsieved does not use the + character in string literals and many
+  clients have adopted to this behaviour. The latest managesieve (08) advises to
+  accept a missing + from clients. The server should not send any + characters
+  as well. This behavior is now implemented on the server.
++ Cleaned up sieve-storage.c: split up the sieve_storage_create function in
+  various sub-functions for obtaining the various paths and directories.
++ Forced manual intervention if rescueing a non-symlink file at the active script
+  path fails somehow. Previously, this presented the admin with a log message
+  that it had just eaten the script, which is not very nice.
++ Restructured the README.managesieve file and added some more explanation with
+  regard to the configuration of the daemon.
+
+v7
+
+- Robin Breathe indicated that the regex capability was missing in the server's
+  SIEVE listing. It turns out I forgot to make arrangements for setting
+  ENABLE_REGEX in the cmu libsieve sources, so the regex extension was not
+  compiled in. I copied the configure.in section regarding ENABLE_REGEX from
+  dovecot-sieve-1.0.2 and that fixed the problem.
+
+v6
+
+- Corked the client output stream while producing the capability greeting and on
+  other some other occasions as well. Some naive client implementations expect to
+  receive this as a single tcp frame and it is a good practice to do so anyway.
+  Using this change the Thunderbird sieve extension (v0.1.1) seemed to work. However,
+  scripts larger than a tcp frame still caused failures. All these issues are fixed
+  in the latest version of the sieve add-on (currently v0.1.4).
+- Cleaned up the new proxy source. My editor made the indentation a complete mess
+  in terms of TABs vs spaces.
+- Added TRYLATER response codes to BYE and NO messages where appropriate.
+- Recopied the libsieve library into this patch to incorporate any changes that were
+  made (only sieve-cmu.c still needs to be compared to the old cmu-sieve.c). This
+  also solves the __attribute__((unused)) GCC dependencies. These were fixed long
+  ago by Timo....  the code duplication beast strikes again.
+- Removed spurious return value from void function in
+  src/lib-sieve/sieve-implementation.c as reported by Robin Breathe. GCC fails to
+  report these issues. The function involved is currently not used and serves only
+  as an example on how dovecot could support multiple sieve backends...
+
+v5
+
+- Applied patch by Uldis Pakuls to fix master_dump_settings bug
+- Added some compilation/installation info to this README
+- Moved README to source tree root as README.managesieve
+- Fixed minor error handling bug in sieve_storage.c with respect to a missing
+  root directory.
+- Now sieve capabilities are reported as they are specified by the implementing
+  library and not in forced upper case. The sieve RFC now explicitly states
+  that sieve capability identifiers are case-sensitive. This broke compatibility
+  with SquirrelMail/Avelsieve.
+- Disabled ANONYMOUS login entirely until proper support is implemented. V4
+  claimed to do so as well, but in fact it only stopped announcing it.
+- Implemented managesieve-proxy. It is not so much a clean copy of imap-proxy,
+  since the managesieve greeting is much more complex and requires parsing.
+  Configuration is identical to imap-proxy. This seems to be a little under-
+  documented however (http://wiki.dovecot.org/PasswordDatabase/ExtraFields).
+
+v4
+
+- Added managesieve_implementation_string setting to the managesieve
+  configuration. This can be used to customize the default "IMPLEMENTATION"
+  capability response.
+- Denied ANONYMOUS login until proper support is implemented
+- Fixed problem with authenticate command regarding continued responses. In
+  V3 only initial response would work. Problem was caused by rc2 -> rc28
+  upgrade. One of the clear reasons why code duplication is a very bad idea.
+- Fixed readlink bug as indicated by Timo: return value of readlink can also
+  be -1.
+- Fixed bug in the regular file rescue code, as introduced in the previous
+  version. Used stat instead of lstat. This caused the symlink to be rescued
+  subsequently in the next activation, thus still overwriting the initially
+  rescued script.
+
+v3
+
+- Updated source to compile with dovecot 1.0.rc27
+- Daemon now uses the same location for .dovecot.sieve as dovecot-lda
+  This is typically ~/.dovecot.sieve
+- If .dovecot.sieve is a regular file, it is now moved into the script storage as
+  dovecot.orig.sieve, preventing deletion of (important) active scripts
+  upon upgrade.
+- Changed error handling to yield a BYE message when the managesieve
+  daemon exits unexpectedly (upon login) before any commands are entered.
+  Horde-ingo would wait indefinitely for a response.
+
+v2
+
+- Fixed the bug (missing CRLF) in the authenticate command
+- Modified the sieve storage library making the interface much less crude.
+- The scripts put on the server using the putscript command are now
+  checked before they are accepted.
+- The reported SIEVE capability is now directly read from the sieve
+  implementation (in this case cmu), listing much more than "FILEINTO
+  VACATION".
+- Imported instance of libsieve source into this patch for implementation
+  of script checking and capability listing. THIS NEEDS TO BE CHANGED!
+- Fixed some minor bugs in the putscript command

+Pigeonhole for Dovecot v2.4
+
+Introduction
+============
+
+This package is part of the Pigeonhole project (http://pigeonhole.dovecot.org).
+It adds support for the Sieve language (RFC 5228) and the ManageSieve protocol
+(RFC 5804) to the Dovecot Secure IMAP Server. In the literal sense, a pigeonhole
+is a a hole or recess inside a dovecot for pigeons to nest in. It is, however,
+also the name for one of a series of small, open compartments in a cabinet used
+for filing or sorting mail. As a verb, it describes the act of putting an item
+into one of those pigeonholes. The name `Pigeonhole' therefore well describes an
+important part of the functionality that this project adds to Dovecot: sorting
+and filing e-mail messages.
+
+The Sieve language is used to specify how e-mail needs to be processed. By
+writing Sieve scripts, users can customize how messages are delivered, e.g.
+whether they are forwarded or stored in special folders. Unwanted messages can
+be discarded or rejected, and, when the user is not available, the Sieve
+interpreter can send an automated reply. Above all, the Sieve language is meant
+to be simple, extensible and system independent. And, unlike most other mail
+filtering script languages, it does not allow users to execute arbitrary
+programs. This is particularly useful to prevent virtual users from having full
+access to the mail store. The intention of the language is to make it impossible
+for users to do anything more complex (and dangerous) than write simple mail
+filters.
+
+Using the ManageSieve protocol, users can upload their Sieve scripts remotely,
+without needing direct filesystem access through FTP or SCP. Additionally, a
+ManageSieve server always makes sure that uploaded scripts are valid, preventing
+compile failures at mail delivery.
+
+This package provides Sieve support as a plugin to Dovecot's Local Delivery
+Agent (LDA) and Dovecot's LMTP service. The ManageSieve protocol is provided is
+an additional service, next to Dovecot's own POP3 and IMAP services.
+
+Features
+========
+
+  * The Pigeonhole Sieve implementation aims to be admin- and user-friendly.
+    Much like Dovecot itself, common error messages are made as easily
+    understandable as possible. Any crash, no matter how it happened, is
+    considered a bug that will be fixed. The compiler does not bail on the first
+    error, but it looks for more script errors to make debugging more efficient.
+
+  * The Pigeonhole Sieve implementation is, much like the Sieve language itself,
+    highly extensible with new Sieve capabilities. This includes support for
+    third-party plugins. It should eventually provide the necessary
+    infrastructure for at least all currently known relevant (proposed) Sieve
+    extensions. The goal is to keep the extension interface provided by the
+    Sieve implementation as generic as possible, i.e. without explicit support
+    for specific extensions. New similar extensions can then use the same
+    interface methods without changes to the Sieve engine code. If an extension
+    is not loaded using the require command, the compiler truly does not know of
+    its existence.
+
+  * The Pigeonhole Sieve plugin is backwards compatible with the old CMUSieve
+    plugin, which provided Sieve support for older versions of Dovecot. All
+    Sieve extensions supported by the old plugin are also supported by the
+    Pigeonhole Sieve plugin, including those that are now considered to be
+    deprecated.
+
+  * The Pigeonhole Sieve implementation supports executing multiple Sieve
+    scripts sequentially. Using this feature it is possible to execute
+    administrator-controlled Sieve scripts before and after the user's personal
+    Sieve script, guaranteeing that responses and message deliveries are never
+    duplicated. This implementation is based on a draft specification
+    (http://tools.ietf.org/html/draft-degener-sieve-multiscript-00), which
+    defines the Sieve behavior when multiple scripts are executed sequentially
+    on the same message.
+
+  * The Pigeonhole Sieve implementation includes a test suite to automatically
+    assess whether the compiled Sieve engine works correctly. The test suite is
+    an extension to the Sieve language and is therefore easily extended with new
+    tests. Currently, the test suite is mostly limited to testing script
+    processing. The performed actions are not tested fully yet.
+
+  * The Pigeonhole Sieve implementation supports the new and very useful
+    variables extension, which allows maintaining state information throughout
+    a Sieve script across subsequent rules.
+
+  * The Pigeonhole Sieve plugin is distributed with a sieve-test tool that
+    simplifies testing Sieve scripts and provides additional debugging
+    facilities.

+
+Compiling and Configuring
+=========================
+
+Refer to INSTALL file.
+
+Sieve Tools
+===========
+
+To test the sieve engine outside deliver, it is useful to try the commands that
+exist in the src/sieve-tools/ directory of this package. After installation,
+these are available at your $prefix/bin directory. The following commands are
+installed:
+
+sievec       - Compiles sieve scripts into a binary representation for later
+               execution. Refer to the next section on manually compiling Sieve
+               scripts.
+
+sieve-test   - This is a universal Sieve test tool for testing the effect of a
+               Sieve script on a particular message. It allows compiling,
+               running and testing Sieve scripts. It can either be used to
+               display the actions that would be performed on the provided test
+               message or it can be used to test the actual delivery of the
+               message and show the messages that would normally be sent through
+               SMTP.
+
+sieve-dump   - Dumps the content of a Sieve binary file for (development)
+               debugging purposes.
+
+sieve-filter - Allow running Sieve filters on messages already stored in a
+               mailbox. 
+
+When installed, man pages are also available for these commands. In this package
+the man pages are present in doc/man and can be viewed before install using
+e.g.:
+
+man -l doc/man/sieve-test.1
+
+Various example scripts are bundled in the directory 'examples'. These scripts
+were downloaded from various locations. View the top comment in the scripts for
+url and author information.
+
+Compiling Sieve Scripts
+=======================
+
+When the LDA Sieve plugin executes a script for the first time (or after it has
+been changed), it is compiled into into a binary form. The Pigeonhole Sieve
+implementation uses the .svbin extension to store compiled Sieve scripts (e.g.
+.dovecot.svbin). To store the binary, the plugin needs write access in the
+directory in which the script is located.
+
+A problem occurs when a global script is encountered by the plugin. For security
+reasons, global script directories are not supposed to be writable by the user.
+Therefore, the plugin cannot store the binary when the script is first compiled.
+Note that this doesn't mean that the old compiled version of the script is used
+when the binary cannot be written: it compiles and uses the current script
+version. The only real problem is that the plugin will not be able to update
+the binary on disk, meaning that the global script needs to be recompiled each
+time it needs to be executed, i.e. for every incoming message, which is
+inefficient.
+
+To mitigate this problem, the administrator must manually pre-compile global
+scripts using the sievec command line tool. For example:
+
+sievec /var/lib/dovecot/sieve/global/
+
+This is often necessary for scripts listed in the sieve_default, sieve_before
+and sieve_after settings. For global scripts that are only included in other
+scripts using the include extension, this step is not necessary, since included
+scripts are incorporated into the binary produced for the main script located in
+a user directory.
+
+Compile and Runtime Logging
+===========================
+
+Log messages produced at runtime by the Sieve plugin are written to two
+locations:
+
+  * Messages are primarily logged to the user log. By default this log file is
+    located in the same directory as the user's main active personal script (as
+    specified by the sieve setting). This log file bears the name of that script
+    file appended with ".log", e.g. ".dovecot.sieve.log". The location of the
+    user log file can also be explicitly configured using the sieve_user_log
+    setting (e.g. for when Sieve scripts are not stored on the local file
+    system).
+
+    If there are errors or warnings in the script, the messages are appended to
+    that log file until it eventually grows too large. When that happens, the
+    old log file is rotated to a ".log.0" file and an empty log file is started.
+    Informational messages are not written to this log file and the log file is
+    not created until messages are actually logged, i.e. when an error or
+    warning is produced.
+
+  * Messages that could be of interest to the system administrator are also
+    written to the Dovecot LDA logging facility (usually syslog). This includes
+    informational messages that indicate what actions are executed on incoming
+    messages. Compile errors encountered in the user's private script are not
+    logged here.
+
+The ManageSieve service reports compile errors and warnings only back to the
+user. System and configuration-related messages are written to the Dovecot
+logging facility.
+
+Known issues
+============
+
+Sieve
+-----
+
+Most open issues are outlined in the TODO file. The more generic ones are (re-)
+listed here:
+
+* Compile errors are sometimes a bit obscure and long. This needs work.
+  Suggestions for improvement are welcome.
+
+* The documentation needs work.
+
+ManageSieve
+-----------
+
+* Although this ManageSieve server should comply with the draft specification of
+  the ManageSieve protocol, quite a few clients don't. This is particularly true
+  for the TLS support. However, now that Cyrus' Timsieved has changed its
+  behavior towards protocol compliance, all those clients will follow
+  eventually.
+
+  Clients known to have TLS issues:
+	- Thunderbird Sieve add-on: fixed as per version 0.1.5
+	- AvelSieve: patch on the wiki:	http://wiki.dovecot.org/ManageSieve
+	- KMail + kio_sieve: TLS broken for old versions. This issue is fixed at
+	  least in kmail 1.9.9 / kde 3.5.9.
+
+  Unfortunately, there is no reliable way to provide a workaround for this
+  problem. We will have to wait for the authors of these clients to make the
+  proper adjustments.
+
+* Other client issues:
+
+	- SmartSieve, WebSieve:
+	  These clients are specifically written for Cyrus timsieved and fail on
+	  multiple stages of the protocol when connected to Pigeonhole ManageSieve.

+Current activities:
+
+* Rework string matching:
+	- Give Sieve its own runtime string type, rather than (ab)using string_t.
+	- Add support for stream matching for handling large values, e.g. from the
+	  body extension.
+	- Improve efficiency of :matches and :contains match types.
+* Build proper comparator support:
+	- Add normalize() method to comparators to normalize the string before
+	  matching (for efficiency).
+	- Allow for the existence of dynamic comparators (i.e. specified by
+	  variables).
+	- Implement comparator-i;unicode-casemap.
+
+Parallel plugin-based efforts (on hold at the moment):
+
+* Implement enotify xmpp method as a plugin.
+
+Next (mostly in order of descending priority/precedence):
+
+* Implement message modification and extraction API in order to:
+	- Properly implement the interaction between editheader and foreverypart/mime.
+	- Implement replace, enclose extensions.
+* Properly implement Sieve internationalization support (utf-8 handling),
+  currently it is not complete:
+	- Make this implementation fully conform section 2.7.2 of RFC5228 (Comparisons
+	  Across Character Sets).
+	- Verify validity of utf8 where necessary.
+* Further develop regex extension and update it to the latest draft:
+	- Implement the :quoteregex set modifier
+	- Investigate the use of the TRE regexp library to gain UTF-8 capability
+	  (posix regexes actually do support utf8, but only when locale is set
+	  accordingly)
+* Finish LDAP Sieve script storage for read-only access.
+	- Consolidate LDAP connections when more than a single Sieve script must be
+	  loaded from different storages linked to the same LDAP server.
+	- Adjust Sieve script API to support asynchronous script retrieval to
+	  retrieve scripts in parallel when possible.
+* Improve error handling.
+	- Implement dropping errors in the user's mailbox as a mail message.
+* Finish body extension:
+	- Build test cases for decoding MIME encodings to UTF-8
+* Cleanup the test suite
+	- Restructure test scripts
+	- Add more comment on purpose of tests
+* Finish the ereject extension
+* Vacation extension improvements:
+	- Implement configurable sender exclusion list.
+	- Implement mechanism for implicitly including an account's aliases in the
+	  vacation command's :addresses list.
+* Fix remaining RFC deviations:
+	- Fix issues listed in doc/rfc/RFC-questions.txt based on answers
+	- Verify outgoing mail addresses at runtime when necessary
+	  (e.g. after variables substitution)
+	- Improve handling of invalid addresses in headers (requires Dovecot changes)
+* Improve sieve_extprograms plugin:
+	- Redesign (forcible) local script termination. It should use SIGCHLD and
+	  a ioloop-based timeout.
+	- Add facility to trigger a temporary failure condition when a program
+	  fails rather than an implicit keep.
+	- Add a method to implicitly pass environment variables such as SENDER and
+	  RECIPIENT through the script socket service.
+* Make testsuite much more exhaustive:
+	- Add support for testing the content of result actions
+	- Test as many error/warning/info conditions as possible.
+	- Review the specification documents and check whether the given requirements
+	  are tested at least once.
+* Fix ManageSieve proxy to recognize response codes from the backend and forward
+  them to the user if appropriate/safe. Probably means implementing a proper
+  ManageSieve client library.
+* Test ManageSieve behavior thoroughly:
+	- Test pipelined behavior
+	- Test proxy authentication
+* Code cleanup:
+	- Make address handling more uniform.
+	- Review all FIXMEs
+
+* Build a server with test mail accounts that processes lots and lots of mail
+  (e.g. spam, mailing lists etc.)
+
+Low priority items:
+
+* Implement extlists extension as a plugin
+* Enotify extension: detect use of variable values extracted from the message
+  that are used in the method argument. RFC reports this as a security issue.
+* Provide a solution for mail_get_headers_utf8 reparsing the whole message each
+  time it is called (header and address test; Timo might provide solution from
+  within Dovecot)
+* Warn during compile if using non-existent folders.
+
+* Variables extension: implement compile time evaluation of constant values
+	- Detect assignment of too large constant values to variables at compile
+	  time.
+* Add development documentation, i.e. comment on library functions and document
+  the binary and byte-code format.
+* Implement sip-message notify mechanism.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH

+The compiler consists of the following stages:
+
+PARSER: sieve-parser.c, sieve-lexer.c
+  Parses the scriptfile and produces an abstract syntax tree for it
+  (sieve-ast.c).
+
+VALIDATOR: sieve-validator.c
+  Performs contextual analysis on the ast produced by the parser. This checks
+  for the validity of commands, tests and arguments. Also, the ast is decorated
+  with any context data acquired during the process. This context is used by the
+  last compiler stage.
+
+GENERATOR: sieve-generator.c
+  This last compiler stage uses a visitor pattern to wander through the ast and
+  produces sieve byte code (sieve-binary.c).
+
+The resulting (in-memory) binary can be fed to the interpreter for execution:
+
+INTERPRETER: sieve-interpreter.c
+  The interpreter executes the byte code and produces a sieve_result object.
+  This result is no more than just a collection of actions to be performed.
+  During execution, action commands add actions to the result. Duplates and
+  conflicts between actions are handled in this execution phase.
+
+RESULT: sieve-result.c sieve-actions.c
+  When the result is to be executed, it needs no further checking, as the
+  validity of the result was verified during interpretation already. The
+  result's actions are executed in a transaction-like atomic manner. If one of
+  the actions fails, the whole transaction is rolled back meaning that either
+  everything succeeds or everything fails. This is only possible to some extent:
+  transmitted responses can of course not be rolled back. However, these are
+  executed in the commit phase, meaning that they will only be performed if all
+  other actions were successful.
+
+Debugging:
+
+BINARY-DUMPER: sieve-code-dumper.c sieve-binary-dumper.c
+  A loaded binary can be dumped to a stream in human-readable form using the
+  binary-dumper. The binary-dumper displays information on all the blocks that
+  the binary consists off. Program code blocks are dumped using the code-dumper.
+  It's implementation is similar to the interpreter, with the exception that it
+  performs no actions and just sequentially wanders through the byte code
+  printing instructions along the way. The term human-readable is a bit optimistic
+  though; currently, the presented data looks like an assembly language.

+Duplicate Extension
+
+Relevant specifications
+=======================
+
+	doc/rfc/duplicate.rfc7352.txt
+
+Description
+===========
+
+The "duplicate" extension adds a new test command called "duplicate" to the
+Sieve language. This test adds the ability to detect duplications. The main
+application for this new test is handling duplicate deliveries commonly caused
+by mailing list subscriptions or redirected mail addresses. The detection is
+normally performed by matching the message ID to an internal list of message
+IDs from previously delivered messages.  For more complex applications, the
+"duplicate" test can also use the content of a specific header field or other
+parts of the message.
+
+Refer to doc/rfc/duplicate.rfc7352.txt for a specification of the Sieve language
+extension. Previously, this extension was Dovecot-specific and available under
+the name "vnd.dovecot.duplicate". That implementation differs significantly from
+what is now published as an RFC, but for backwards compatibility the original
+extension is still supported.
+
+Configuration
+=============
+
+The "duplicate" extension is available by default. The "duplicate" extension has
+its own specific settings. The following settings are available (default
+values are indicated):
+
+sieve_duplicate_default_period = 14d
+sieve_duplicate_max_period = 7d
+  These options respectively specify the default and the maximum value for the
+  period after which tracked values are purged from the duplicate tracking
+  database. The period is specified in s(econds), unless followed by a d(ay),
+  h(our) or m(inute) specifier character.
+
+Example
+=======
+
+plugin {
+  sieve = ~/.dovecot.sieve
+
+  sieve_duplicate_default_period = 1h
+	sieve_duplicate_max_period = 1d
+}

+Editheader Extension
+
+Relevant specifications
+=======================
+
+  RFC5293 - doc/rfc/editheader.rfc5293.txt
+
+Description
+===========
+
+The editheader extension [RFC5293] enables Sieve scripts to delete and add
+message header fields, thereby allowing interaction with other components that
+consume or produce header fields.
+
+Configuration
+=============
+
+The editheader extension is not available by default and needs to be enabled
+explicitly by adding it to the sieve_extensions setting.
+
+The following settings can be configured for the editheader extension (default
+values are indicated):
+
+sieve_editheader_max_header_size = 2048
+  The maximum size in bytes of a header field value passed to the addheader
+  command. The minimum value for this setting is 1024 bytes. The value is in
+  bytes, unless followed by a k(ilo).
+
+sieve_editheader_forbid_add =
+  A space-separated list of headers that cannot be added to the message header.
+  Addition of the `Subject:' header cannot be prohibited, as required by the RFC
+  specification. Therefore, adding this header to this setting has no effect.
+
+sieve_editheader_forbid_delete =
+  A space-separated list of headers that cannot be deleted from the message
+  header. Deleting the `Received:' and `Auto-Submitted:' fields is always 
+  forbidden, while removing the `Subject:' header cannot be prohibited,
+  as required by the RFC specification. Therefore, adding one of these headers
+  to this setting has no effect.
+
+sieve_editheader_protected =
+  A space-separated list of headers that cannot be added to or deleted from
+  the message header. This setting is provided for backwards compatibility. It
+  is a combination of the sieve_editheader_forbid_add and
+  sieve_editheader_forbid_delete settings. The same limitations apply. 
+
+Invalid values for the settings above will make the Sieve interpreter log
+a warning and revert to the default values.
+
+Example
+=======
+
+plugin {
+  # Use editheader
+  sieve_extensions = +editheader
+
+  # Header fiels must not exceed one 1k
+  sieve_editheader_max_header_size = 1k
+
+  # Protected special headers
+  sieve_editheader_forbid_add = X-Verified
+  sieve_editheader_forbid_delete = X-Verified X-Seen

+Include Extension
+
+Relevant Specifications
+=======================
+
+  draft-ietf-sieve-include-05 - doc/rfc/draft-ietf-sieve-include-05.txt
+
+Description
+===========
+
+The Sieve include extension permits users to include one Sieve script into
+another. This can make managing large scripts or multiple sets of scripts much
+easier, and allows a site and its users to build up libraries of scripts. Users
+are able to include their own personal scripts or site-wide scripts.
+
+Included scripts can include more scripts of their own, yielding a tree of
+included scripts with the main script (typically the user's personal script) at
+its root.
+
+Configuration
+=============
+
+The include extension is available by default. The include extension has its own
+specific settings. The following settings can be configured for the include
+extension (default values are indicated):
+
+sieve_include_max_includes = 255
+  The maximum number of scripts that may be included. This is the total number
+  of scripts involved in the include tree.
+
+sieve_include_max_nesting_depth = 10
+  The maximum nesting depth for the include tree.

+Spamtest and Virustest Extensions
+
+Relevant Specifications
+=======================
+
+  RFC5235 - doc/rfc/spamvirustest.rfc5235.txt
+
+Description
+===========
+
+Using the spamtest and virustest extensions (RFC 5235), the Sieve language
+provides a uniform and standardized command interface for evaluating spam and
+virus tests performed on the message. Users no longer need to know what headers
+need to be checked and how the scanner's verdict is represented in the header
+field value. They only need to know how to use the spamtest (spamtestplus) and
+virustest extensions. This also gives GUI-based Sieve editors the means to
+provide a portable and easy to install interface for spam and virus filter
+configuration. The burden of specifying which headers need to be checked and how
+the scanner output is represented falls onto the Sieve administrator.
+
+Configuration
+=============
+
+The spamtest, spamtestplus and virustest extensions are not enabled by default
+and thus need to be enabled explicitly using the sieve_extensions setting.
+
+The following settings need to be configured for using the spamtest and
+spamtestplus extensions. The virustest extension has identical configuration
+settings, but with a `sieve_virustest_' prefix instead of a `sieve_spamtest_'
+prefix:
+
+sieve_spamtest_status_type = "score" / "strlen" / "text"
+  This specifies the type of status result that the spam/virus scanner produces.
+  This can either be a numeric score ("score"), a string of identical characters
+  ("strlen"), e.g. '*******', or a textual description, e.g. `Spam'
+  or `Not Spam'.
+
+sieve_spamtest_status_header = <header-field> [ ":" <regexp> ]
+  This specifies the header field that contains the result information of the
+  spam scanner and it may express the syntax of the content of the header. If no
+  matching header is found in the message, the spamtest command will match
+  against "0".
+
+  This is a structured setting. The first part specifies the header field name.
+  Optionally, an extended POSIX regular expression follows the header field
+  name, separated by a colon. Any whitespace directly following the colon is not
+  part of the regular expression. If the regular expression is omitted, any
+  header content is accepted and the full header value is used. When a regular
+  expression is used, it must specify one match value (inside brackets) that
+  yields the desired spam scanner result. If the header does not match the
+  regular expression or if no value match is found, the spamtest will match
+  against "0".
+
+sieve_spamtest_max_value =
+  This statically specifies the maximum value a numeric spam score can have.
+
+sieve_spamtest_max_header = <header-field> [ ":" <regexp> ]
+  Some spam scanners include the maximum score value in one of their status
+  headers. Using this setting, this maximum can be extracted from the message
+  itself instead of specifying the maximum manually using the setting
+  `sieve_spamtest_max_value' explained above. The syntax is identical to the
+  `sieve_spamtext_status_header' setting.
+
+sieve_spamtest_text_valueX =
+  When the `sieve_spamtest_status_type' setting is set to "text", these settings
+  specify that the spamtest command will match against "X" when the specified
+  string is equal to the text (extracted) from the status header. For spamtest,
+  values of X between 0 and 10 are recognized, while virustest only uses values
+  between 0 and 5.
+
+Examples
+========
+
+This section shows several configuration examples. Each example shows a specimen
+of valid virus/spam test headers that the given configuration will work on.
+
+Example 1
+---------
+
+Spam header: `X-Spam-Score: No, score=-3.2'
+
+plugin {
+  sieve_extensions = +spamtest +spamtestplus
+
+  sieve_spamtest_status_type = score
+  sieve_spamtest_status_header = \
+    X-Spam-Score: [[:alnum:]]+, score=(-?[[:digit:]]+\.[[:digit:]])
+  sieve_spamtest_max_value = 5.0
+}
+
+Example 2
+---------
+
+Spam header: `X-Spam-Status: Yes'
+
+plugin {
+  sieve_extensions = +spamtest +spamtestplus
+
+  sieve_spamtest_status_type = text
+  sieve_spamtest_status_header = X-Spam-Status
+  sieve_spamtest_text_value1 = No
+  sieve_spamtest_text_value10 = Yes
+}
+
+Example 3
+---------
+
+Spam header: `X-Spam-Score: sssssss'
+
+plugin {
+  sieve_extensions = +spamtest +spamtestplus
+
+  sieve_spamtest_status_header = X-Spam-Score
+  sieve_spamtest_status_type = strlen
+  sieve_spamtest_max_value = 5
+}
+
+Example 4
+---------
+
+Spam header: `X-Spam-Score: status=3.2 required=5.0'
+Virus header: `X-Virus-Scan: Found to be clean.'
+
+plugin {
+  sieve_extensions = +spamtest +spamtestplus +virustest
+
+  sieve_spamtest_status_type = score
+  sieve_spamtest_status_header = \
+    X-Spam-Score: score=(-?[[:digit:]]+\.[[:digit:]]).*
+  sieve_spamtest_max_header = \
+    X-Spam-Score: score=-?[[:digit:]]+\.[[:digit:]] required=([[:digit:]]+\.[[:digit:]])
+
+  sieve_virustest_status_type = text
+  sieve_virustest_status_header = X-Virus-Scan: Found to be (.+)\.
+  sieve_virustest_text_value1 = clean
+  sieve_virustest_text_value5 = infected

+Vacation Extension
+
+Relevant specifications
+=======================
+
+  RFC5230 - doc/rfc/vacation.rfc5230.txt
+  RFC6131 - doc/rfc/vacation-seconds.rfc6131.txt
+
+Description
+===========
+
+The Sieve vacation extension [RFC5230] defines a mechanism to generate automatic
+replies to incoming email messages. It takes various precautions to make sure
+replies are only sent when appropriate. Script authors specify how often replies
+are sent to a particular contact. In the original vacation extension, this
+interval is specified in days with a minimum of one day. When more granularity
+is necessary and particularly when replies must be sent more frequently than one
+day, the vacation-seconds extension [RFC6131] can be used. This allows
+specifying the minimum reply interval in seconds with a minimum of zero (reply
+is then always sent), depending on administrator configuration.
+
+Configuration
+=============
+
+The vacation extension is available by default. In contrast, the
+vacation-seconds extension - which implies the vacation extension when used - is
+not available by default and needs to be enabled explicitly by adding it to the
+sieve_extensions setting. The configuration also needs to be adjusted
+accordingly to allow a non-reply period of less than a day.
+
+The vacation and vacation-seconds extensions have their own specific settings.
+The settings that specify a period are specified in s(econds), unless followed
+by a d(ay), h(our) or m(inute) specifier character.
+
+The following settings can be configured for the vacation extension (default
+values are indicated):
+
+sieve_vacation_min_period = 1d
+  This specifies the minimum period that can be specified for the :days and
+  :seconds tags of the vacation command. A minimum of 0 indicates that users are
+  allowed to make the Sieve interpreter send a vacation response message for
+  every incoming message that meets the other reply criteria (refer to RFC5230).
+  A value of zero is however not recommended.
+
+sieve_vacation_max_period = 0
+  This specifies the maximum period that can be specified for the :days tag of
+  the vacation command. The configured value must be larger than the
+  sieve_vacation_min_period setting. A value of 0 has a special meaning: it
+  indicates that there is no upper limit.
+
+sieve_vacation_default_period = 7d
+  This specifies the default period that is used when no :days or :seconds tag
+  is specified. The configured value must lie between the
+  sieve_vacation_min_period and sieve_vacation_max_period.
+
+sieve_vacation_max_subject_codepoints = 256
+  The maximum number of Unicode codepoints used in the Subject header generated
+  for the outgoing vacation message. When composite characters are involved,
+  the number of actual charactes in the Subject text can be less than this
+  number, otherwise it is equal. When the subject text exceeds the limit, it is
+  truncated and the removed part is replaced with an ellipsis character ('...').
+
+sieve_vacation_use_original_recipient = no
+  This specifies whether the original envelope recipient should be used in the
+  check for implicit delivery.  The vacation command checks headers of the
+  incoming message, such as To: and Cc: for the address of the recipient, to
+  verify that the message is explicitly addressed at the recipient. If the
+  recipient address is not found, the vacation action will not trigger a
+  response to prevent sending a reply when it is not appropriate. Normally only
+  the final recipient address is used in this check. This setting allows
+  including the original recipient specified in the SMTP session if available.
+  This is useful to handle mail accounts with aliases. Use this option with
+  caution: if you are using aliases that point to more than a single account,
+  senders can get multiple vacation responses for a single message.
+
+sieve_vacation_dont_check_recipient = no
+  This disables the checks for implicit delivery entirely. This means that the
+  vacation command does not verify that the message is explicitly addressed at
+  the recipient. Use this option with caution. Specifying 'yes' will violate the
+  Sieve standards and can cause vacation replies to be sent for messages not
+  directly addressed at the recipient.
+
+sieve_vacation_send_from_recipient = no
+  This setting determines whether vacation messages are sent with the SMTP MAIL
+  FROM envelope address set to the recipient address of the Sieve script owner.
+  Normally this is set to <>, which is the default as recommended in the
+  specification. This is meant to prevent mail loops. However, there are
+  situations for which a valid sender address is required and this setting can
+  be used to accommodate for those.
+
+sieve_vacation_to_header_ignore_envelope = no
+  With this setting disabled (the default), the "To:" header in the composed
+  vacation reply is determined by finding the envelope sender address in the
+  first "Sender:", "Resent-From:", or "From:" headers (in that order). The
+  matching address is used in the "To:" header of the reply, which then includes
+  the "phrase" part of the address; i.e., usually the name of the person
+  associated with that address. If no match is found, the bare envelope sender
+  address is used instead. In contrast, with this setting enabled, the envelope
+  is completely ignored for this purpose and the first address found from the
+  mentioned headers is always used. This is useful when the envelope sender is
+  mangled somehow; e.g. by the Sender Rewriting Scheme (SRS).
+
+Invalid values for the settings above will make the Sieve interpreter log a
+warning and revert to the default values.
+
+Example
+=======
+
+plugin {
+  # Use vacation-seconds
+  sieve_extensions = +vacation-seconds
+
+  # One hour at minimum
+  sieve_vacation_min_period = 1h
+
+  # Ten days default
+  sieve_vacation_min_period = 10d
+
+  # Thirty days at maximum
+  sieve_vacation_max_period = 30d
+}

+Vnd.dovecot.environment Extension
+
+Relevant specifications
+=======================
+
+  doc/rfc/spec-bosch-sieve-dovecot-environment.txt
+
+Description
+===========
+
+The "vnd.dovecot.environment" extension builds upon the existing standard
+"environment" extension, which allows Sieve scripts to access information about
+their execution context, such as the name and version of the Sieve interpreter
+implementation. The new "vnd.dovecot.environment" extension adds a few more
+environment items that can be accessed by Sieve scripts. Additionally, it makes
+the environment items available directly as variables [VARIABLES].
+
+Configuration
+=============
+
+The "vnd.dovecot.environment" extension is not available by default; it needs
+to be added to the sieve_extensions or (rather) the sieve_global extensions
+setting.
+
+Currently, the "vnd.dovecot.environment" extension has no specific settings.
+However, this extension adds environment items with a "vnd.dovecot.config."
+prefix that can be used to access part of the Dovecot configuration. An
+environment item named "vnd.dovecot.config.identifier" yields the value of a
+plugin setting called "sieve_env_identifier".
+
+Example
+=======
+
+With the following configuration:
+
+plugin {
+  sieve = ~/.dovecot.sieve
+
+  sieve_env_reject_reason = Please don't mail me.
+}
+
+The following script will reject the message with the configured reason:
+
+require "reject";
+require "variables";
+require "vnd.dovecot.environment";
+
+reject "${vnd.dovecot.config.reject_reason}";

+Vnd.dovecot.report Extension
+
+Relevant specifications
+=======================
+
+  doc/rfc/spec-bosch-sieve-report.txt
+
+Description
+===========
+
+The "vnd.dovecot.report" extension provides the means to send Messaging Abuse
+Reporting Format (MARF) reports (RFC 5965). This format is intended for
+communications regarding email abuse and related issues.  The "report" command
+allows (partially) automating the exchange of these reports, which is
+particularly useful when the Sieve script is executed for an IMAP event
+(RFC 6785) that is triggered by direct user action.
+
+Configuration
+=============
+
+The "vnd.dovecot.report" extension is not available by default; it needs
+to be added to the sieve_extensions setting (or any of the alternatives).
+
+The "vnd.dovecot.report" extension has its own specific settings. The following
+settings can be configured for the vacation extension (default values are
+indicated):
+
+ sieve_report_from = postmaster
+   Specifies what address is used for the "From:" header field in reports.
+   The following values are supported for this setting:
+   
+     "postmaster"     - The postmaster_address configured for the LDA (default).
+     "sender"         - The sender address is used.
+     "recipient"      - The final recipient address is used.
+     "orig_recipient" - The original recipient is used.
+     "user_email"     - The user's primary address is used. This is
+                        configured with the "sieve_user_email" setting. If
+                        that setting is unconfigured, "user_mail" is equal to
+                        "recipient".
+     "<user@domain>"  - Redirected messages are always sent from user@domain.
+                        The angle brackets are mandatory. The null "<>" address
+                        not supported and interpreted as "postmaster".
+
+Invalid values for the settings above will make the Sieve interpreter log a
+warning and revert to the default values.
+
+Example
+=======
+
+plugin {
+  sieve = file:~/sieve;active=~/.dovecot.sieve
+
+  sieve_report_from = <reporter@example.com>
+}

+DICT Sieve Script Location Type
+
+Description
+===========
+
+This location type is used to retrieve Sieve scripts from a Dovecot dict lookup.
+Such dictionaries use a file or an SQL database as backend. Refer to the Dovecot
+dict documentation for more information on dict lookups.
+
+To retrieve a Sieve script from the dict database, two lookups are performed.
+First, the name of the Sieve script is queried from the dict path
+`/priv/sieve/name/<name>'. If the Sieve script exists, this yields a data ID
+which in turn points to the actual script text. The script text is subsequently
+queried from the dict path '/priv/sieve/data/<dict-id>'.
+
+The second query is only necessary when no compiled binary is available or when
+the script has changed and needs to be recompiled. The data ID is used to detect
+changes in the dict's underlying database. Changing a Sieve script in the
+database must be done by first making a new script data item with a new data ID.
+Then, the mapping from name to data ID must be changed to point to the new
+script text, thereby changing the data ID returned from the name lookup, i.e.
+the first query mentioned above. Script binaries compiled from Sieve scripts
+contained in a dict database record the data ID. While the data ID contained in
+the binary is identical to the one returned from the dict lookup, the binary is
+assumed up-to-date. When the returned data ID is different, the new script text
+is retrieved using the second query and compiled into a new binary containing
+the updated data ID.
+
+Note that, by default, compiled binaries are not stored at all for Sieve scripts
+retrieved from a dict database. The bindir= option needs to be specified in the
+location specification. Refer to the INSTALL file for more general information
+about configuration of script locations.
+
+Configuration
+=============
+
+The script location syntax is specified as follows:
+
+location = dict:<dict-uri>[;<option>[=<value>][;...]]
+
+The following additional options are recognized:
+
+  user=<username>
+    Overrides the user name used for the dict lookup. Normally, the name of the
+    user running the Sieve interpreter is used.
+
+If the name of the Script is left unspecified and not otherwise provided by the
+Sieve interpreter, the name defaults to `default'.
+
+Examples
+========
+
+Example 1
+---------
+
+This example is mainly useful for performing a quick test of the dict location
+configuration without configuring an actual (SQL) database. For this example, a
+very simple file dict is assumed to be contained in the file
+/etc/dovecot/sieve.dict:
+
+priv/sieve/name/keep
+1
+priv/sieve/name/discard
+2
+priv/sieve/name/spam
+3
+priv/sieve/data/1
+keep;
+priv/sieve/data/2
+discard;
+priv/sieve/data/3
+require ["fileinto", "mailbox"]; fileinto :create "spam";
+
+To use this file dict for the main active script, you can change the
+configuration as follows (e.g. in /etc/dovecot/conf.d/90-sieve.conf):
+
+plugin {
+  sieve = dict:file:/etc/dovecot/sieve.dict;name=keep;bindir=~/.sieve-bin
+}
+
+The Sieve script named "keep" is retrieved from the file dict as the main
+script. Binaries are stored in the ~/.sieve-bin directory.
+
+Example 2
+---------
+
+This example uses a PostgreSQL database. Our database contains the following
+table:
+
+CREATE TABLE user_sieve_scripts (
+  id integer,
+  username varchar(40),
+  script_name varchar(256),
+  script_data varchar(10240),
+
+  PRIMARY KEY (id),
+  UNIQUE(username, script_name)
+);
+
+We create a file /etc/dovecot/dict-sieve-sql.conf with the following content:
+
+connect = host=localhost dbname=dovecot user=dovecot password=password
+map {
+  pattern = priv/sieve/name/$script_name
+  table = user_sieve_scripts
+  username_field = username
+  value_field = id
+  fields {
+    script_name = $script_name
+  }
+}
+map {
+  pattern = priv/sieve/data/$id
+  table = user_sieve_scripts
+  username_field = username
+  value_field = script_data
+  fields {
+    id = $id
+  }
+}
+
+These are the mappings used by the SQL dict. The first mapping is the name query
+that yields the id of the Sieve script. The second mapping is the query used to
+retrieve the Sieve script itself.
+
+Much like the dict configuration for mailbox quota, it is often not possible to
+directly use an SQL dict because the SQL drivers are not linked to binaries such
+as dovecot-lda and lmtp. You need to use the dict proxy service. Add the dict
+URI to the dict section (typically located in your main dovecot.conf):
+
+dict {
+  sieve = pgsql:/etc/dovecot/dict-sieve-sql.conf.ext
+}
+
+To use this SQL dict for the main active script, you can change the
+configuration as follows (e.g. in /etc/dovecot/conf.d/90-sieve.conf):
+
+plugin {
+  sieve = dict:proxy::sieve;name=active;bindir=~/.sieve-bin
+}
+
+This uses the proxy dict uri `proxy::sieve'. This refers to the `sieve =' entry
+in the dict {...} section above. With this configuration, a Sieve script called
+"main" is retrieved from the SQL dict. Binaries are stored in the ~/.sieve-bin
+directory.

+FILE Sieve Script Location Type
+
+Description
+===========
+
+This location type is used to retrieve Sieve scripts from the file system. The
+location can either point to a directory or to a regular file. If the location
+points to a directory, a script called "name" is retrieved by reading a file
+from that directory with the file name "name.sieve".
+
+When this location type is involved in a sieve_before/sieve_after script
+sequence and the location points to a directory, all files in that directory
+with a ".sieve" extension are part of the sequence. The sequence order of the
+scripts in that directory is determined by the file names, using a normal 8bit
+per-character comparison.
+ 
+Unless overridden using the `bindir=<path>' location option, compiled binaries
+for scripts retrieved from the `file' location type are by default stored in the
+same directory as where the script file was found if possible. Refer to the
+INSTALL file for more general information about configuration of script
+locations.
+
+Configuration
+=============
+
+The script location syntax is specified as follows:
+
+location = file:<path>[;<option>[=<value>][;...]]
+
+The following additional options are recognized:
+
+  active=<path>
+    When ManageSieve is used, one script in the storage can be active; i.e.,
+    evaluated at delivery. For the `file' location, the active script in the
+    storage directory is pointed to by a symbolic link. This option configures
+    where this symbolic link is located. If the `file' location path points to
+    a regular file, this setting has no effect (and ManageSieve cannot be used).
+
+Example
+=======
+
+plugin {
+	...
+  sieve = file:~/sieve;active=~/.dovecot.sieve
+
+  sieve_default = file:/var/lib/dovecot/;name=default
+}

+LDAP Sieve Script Location Type
+
+Description
+===========
+
+This location type is used to retrieve Sieve scripts from an LDAP database. To
+retrieve a Sieve script from the LDAP database, at most two lookups are
+performed. First, the LDAP entry containing the Sieve script is searched using
+the specified LDAP search filter. If the LDAP entry changed since it was last
+retrieved (or it was never retieved before), the attribute containing the actual
+Sieve script is retrieved in a second lookup. In the first lookup, a special
+attribute is read and checked for changes. Usually, this is the
+`modifyTimestamp' attribute, but an alternative can be configured.
+
+Note that, by default, compiled binaries are not stored at all for Sieve scripts
+retrieved from an LDAP database. The bindir= option needs to be specified in the
+location specification. Refer to the INSTALL file for more general information
+about configuration of script locations.
+
+Depending on how Pigeonhole was configured and compiled (refer to INSTALL file
+for more information), LDAP support may only be available from a plugin called
+`sieve_storage_ldap'.
+
+Configuration
+=============
+
+If support for the LDAP location type is compiled as a plugin, it needs to be
+added to the sieve_plugins setting before it can be used, e.g.:
+
+sieve_plugins = sieve_storage_ldap
+
+The script location syntax is specified as follows:
+
+location = ldap:<config-file>[;<option>[=<value>][;...]]
+
+The <config-file> is a filesystem path that points to a configuration file
+containing the actual configuration for this LDAP script location.
+
+The following additional location options are recognized:
+
+  user=<username>
+    Overrides the user name used for the lookup. Normally, the name of the
+    user running the Sieve interpreter is used.
+
+If the name of the Script is left unspecified and not otherwise provided by the
+Sieve interpreter, the name defaults to `default'.
+
+The configuration file is based on the auth userdb/passdb LDAP configuration
+(refer to Dovecot wiki at http://wiki2.dovecot.org/AuthDatabase/LDAP). The
+following options are specific to the Sieve ldap location type:
+
+  sieve_ldap_filter = (&(objectClass=posixAccount)(uid=%u))
+    The LDAP search filter that is used to find the entry containing the Sieve
+    script.
+
+  sieve_ldap_script_attr = mailSieveRuleSource
+    The name of the attribute containing the Sieve script itself.
+
+  sieve_ldap_mod_attr = modifyTimestamp
+    The name of the attribute used to detect modifications to the LDAP entry.
+	
+Examples
+========
+
+plugin {
+  sieve = ldap:/etc/dovecot/sieve-ldap.conf;bindir=~/.sieve-bin/
+}
+
+An example LDAP location configuration is available in this package as
+doc/example-config/sieve-ldap.conf.

+.\"------------------------------------------------------------------------
+.SH NAME
+pigeonhole \- Overview of the Pigeonhole project\(aqs Sieve support for the
+Dovecot secure IMAP and POP3 server
+.\"------------------------------------------------------------------------
+.SH DESCRIPTION
+.PP
+The Pigeonhole project <http://pigeonhole.dovecot.org> adds support for the
+Sieve language (RFC 5228) and the ManageSieve protocol (RFC 5804) to the
+Dovecot Secure IMAP and POP3 Server (\fBdovecot\fR(1)). In the literal sense,
+a pigeonhole is a a hole or recess inside a dovecot for pigeons to nest in.
+It is, however, also the name for one of a series of small, open compartments
+in a cabinet used for filing or sorting mail. As a verb, it describes the act
+of putting an item into one of those pigeonholes. The name \(dqPigeonhole\(dq
+therefore well describes an important part of the functionality that this
+project adds to Dovecot: sorting and filing e\-mail messages.
+.PP
+The Sieve language is used to specify how e\-mail needs to be processed. By
+writing Sieve scripts, users can customize how messages are delivered, e.g.
+whether they are forwarded or stored in special folders. Unwanted messages can
+be discarded or rejected, and, when the user is not available, the Sieve
+interpreter can send an automated reply. Above all, the Sieve language is meant
+to be simple, extensible and system independent. And, unlike most other mail
+filtering script languages, it does not allow users to execute arbitrary
+programs. This is particularly useful to prevent virtual users from having full
+access to the mail store. The intention of the language is to make it impossible
+for users to do anything more complex (and dangerous) than write simple mail
+filters.
+.PP
+Using the ManageSieve protocol, users can upload their Sieve scripts remotely,
+without needing direct filesystem access through FTP or SCP. Additionally, a
+ManageSieve server always makes sure that uploaded scripts are valid, preventing
+compile failures at mail delivery.
+.PP
+The Pigeonhole project provides the following items:
+.IP \(bu 4
+The LDA Sieve plugin for Dovecot\(aqs Local Delivery Agent (LDA)
+(\fBdovecot\-lda\fR(1)) that facilitates the actual Sieve filtering upon
+delivery.
+.IP \(bu
+The ManageSieve service that implements the ManageSieve protocol through which
+users can remotely manage Sieve scripts on the server.
+.IP \(bu
+A plugin for Dovecot\(aqs
+.BR doveadm (1)
+command line tool that adds new the new
+.BR doveadm-sieve (1)
+commands for management of Sieve filtering.
+.PP
+The functionality and configuration of the LDA Sieve plugin and the ManageSieve
+service is described in detail in the README and INSTALL files contained in the
+Pigeonhole package and in the Dovecot Wiki
+<http://wiki2.dovecot.org/Pigeonhole>.
+.PP
+The following command line tools are available outside of
+.BR doveadm :
+.TP
+.BR sievec (1)
+Compiles Sieve scripts into a binary representation for later execution.
+.TP
+.BR sieve\-test (1)
+The universal Sieve test tool for testing the effect of a Sieve script on a
+particular message.
+.TP
+.BR sieve\-filter (1)
+Filters all messages in a particular source mailbox through a Sieve script.
+.TP
+.BR sieve\-dump (1)
+Dumps the content of a Sieve binary file for (development) debugging purposes.

+.SH NAME
+sieve\-dump \- Pigeonhole\(aqs Sieve script binary dump tool
+.\"------------------------------------------------------------------------
+.SH SYNOPSIS
+.B sieve\-dump
+.RI [ options ]
+.I sieve\-binary
+.RI [ out\-file ]
+.\"------------------------------------------------------------------------
+.SH DESCRIPTION
+.PP
+The \fBsieve\-dump\fP command is part of the Pigeonhole Project
+(\fBpigeonhole\fR(7)), which adds Sieve (RFC 5228) support to the Dovecot
+secure IMAP and POP3 server (\fBdovecot\fR(1)).
+.PP
+Using the \fBsieve\-dump\fP command, Sieve binaries, which are produced for
+instance by \fBsievec\fP(1), can be transformed into a human\-readable textual
+representation. This can provide valuable insight in how the Sieve script is
+executed. This is also particularly useful to view corrupt binaries that can
+result from bugs in the Sieve implementation. This tool is intended mainly for
+development purposes, so normally system administrators and users will not need
+to use this tool.
+.PP
+The format of the output is not explained here in detail, but it should be
+relatively easy to understand. The Sieve binaries comprise a set of data blocks,
+each of which can contain arbitrary data. For the base language implementation
+two blocks are used: the first containing a specification of all required
+language extensions and the second containing the main Sieve program. Compiled
+Sieve programs are represented as flat byte code and therefore the dump of the
+main program is a disassembly listing of the interpreter operations. Extensions
+can define new operations and use additional blocks. Therefore, the output of
+\fBsieve\-dump\fP depends greatly on the language extensions used when compiling
+the binary.
+.\"------------------------------------------------------------------------
+.SH OPTIONS
+.TP
+.BI \-c\  config\-file
+Alternative Dovecot configuration file path.
+.TP
+.B \-D
+Enable Sieve debugging.
+.TP
+.B \-h
+Produce per\-block hexdump output of the whole binary instead of the normal
+human\-readable output.
+.TP
+.BI \-o\  setting = value
+Overrides the configuration
+.I setting
+from
+.I @pkgsysconfdir@/dovecot.conf
+and from the userdb with the given
+.IR value .
+In order to override multiple settings, the
+.B \-o
+option may be specified multiple times.
+.TP
+.BI \-u\  user
+Run the Sieve script for the given \fIuser\fP. When omitted, the
+.I command
+will be executed with the environment of the currently logged in user.
+.TP
+.BI \-x\  extensions
+Set the available extensions. The parameter is a space\-separated list of the
+active extensions. By prepending the extension identifiers with \fB+\fP or
+\fB\-\fP, extensions can be included or excluded relative to the configured set
+of active extensions. If no extensions have a \fB+\fP or \fB\-\fP prefix, only
+those extensions that are explicitly listed will be enabled. Unknown extensions
+are ignored and a warning is produced.
+
+For example \fB\-x\fP \(dq+imapflags \-enotify\(dq will enable the deprecated
+imapflags extension and disable the enotify extension. The rest of the active
+extensions depends on the \fIsieve_extensions\fP and
+\fIsieve_global_extensions\fP settings. By default, i.e.
+when \fIsieve_extensions\fP and \fIsieve_global_extensions\fP remain
+unconfigured, all supported extensions are available, except for deprecated
+extensions or those that are still under development.
+
+.\"------------------------------------------------------------------------
+.SH ARGUMENTS
+.TP
+.I sieve\-binary
+Specifies the Sieve binary file that needs to be dumped.
+.TP
+.I out\-file
+Specifies where the output must be written. This argument is optional. If
+omitted, the output is written to \fBstdout\fR.
+.\"------------------------------------------------------------------------
+.SH "EXIT STATUS"
+.B sieve\-dump
+will exit with one of the following values:
+.TP 4
+.B 0
+Dump was successful. (EX_OK, EXIT_SUCCESS)
+.TP
+.B 1
+Operation failed. This is returned for almost all failures.
+(EXIT_FAILURE)
+.TP
+.B 64

+.SH SYNOPSIS
+.B sieve\-filter
+.RI [ options ]
+.I script\-file
+.I source\-mailbox
+.RI [ discard\-action ]
+.SH DESCRIPTION
+.PP
+The \fBsieve\-filter\fP command is part of the Pigeonhole Project
+(\fBpigeonhole\fR(7)), which adds Sieve (RFC 5228) support to the Dovecot
+secure IMAP and POP3 server (\fBdovecot\fR(1)).
+.PP
+The Sieve language was originally meant for filtering messages upon delivery.
+However, there are occasions when it is desirable to filter messages that are
+already stored in a mailbox, for instance when a bug in a Sieve script caused
+many messages to be delivered incorrectly. Using the sieve\-filter tool it is
+possible to apply a Sieve script on all messages in a particular
+\fIsource\-mailbox\fP, making it possible to delete messages, to store them in a
+different mailbox, to change their content, and to change the assigned IMAP
+flags and keywords. Attempts to send messages to the outside world are ignored
+by default for obvious reasons, but, using the proper command line options, it
+is possible to capture and handle outgoing mail as well.
+.PP
+If no options are specified, the sieve\-filter command runs in a simulation mode
+in which it only prints what would be performed, without actually doing
+anything. Use the \fB\-e\fP option to activate true script execution. Also, the
+\fIsource\-mailbox\fP is opened read\-only by default, meaning that it normally
+always remains unchanged. Use the \fB\-W\fP option to allow changes in the
+\fIsource\-mailbox\fP.
+.PP
+Even with the \fB\-W\fP option enabled, messages in the \fIsource\-mailbox\fP
+are only potentially modified or moved to a different folder. Messages are never
+lost unless a \fIdiscard\-action\fP argument other than \fBkeep\fP (the default)
+is specified. If the Sieve filter decides to store the message in the
+\fIsource\-mailbox\fP, where it obviously already exists, it is never duplicated
+there. In that case, the IMAP flags of the original message can be modified by
+the Sieve interpreter using the \fIimap4flags\fP extension, provided that
+\fB\-W\fP is specified. If the message itself is modified by the Sieve
+interpreter (e.g. using the \fIeditheader\fP extension), a new message is stored
+and the old one is expunged. However, if \fB-W\fP is omitted, the original
+message is left untouched and the modifications are discarded.
+
+.SS CAUTION
+Although this is a very useful tool, it can also be very destructive when used
+improperly. A small bug in your Sieve script in combination with the wrong
+command line options could cause it to discard the wrong e\-mails. And, even if
+the \fIsource\-mailbox\fP is opened in read\-only mode to prevent such mishaps,
+it can still litter other mailboxes with spurious copies of your e\-mails if
+your Sieve script decides to do so. Therefore, users are advised to read this
+manual carefully and to use the simulation mode first to check what the script
+will do. And, of course:

+\fBMAKING A BACKUP IS IMPERATIVE FOR ANY IMPORTANT MAIL!\fP
+
+.\"------------------------------------------------------------------------
+.SH OPTIONS
+.TP
+.BI \-c\  config\-file
+Alternative Dovecot configuration file path.
+.TP
+.B \-C
+Force compilation. By default, the compiled binary is stored on disk. When this
+binary is found during the next execution of \fBsieve\-filter\fP and its
+modification time is more recent than the script file, it is used and the script
+is not compiled again. This option forces the script to be compiled, thus
+ignoring any present binary. Refer to \fBsievec\fP(1) for more information about
+Sieve compilation.
+.TP
+.B \-D
+Enable Sieve debugging.
+.TP
+.B \-e
+Turns on execution mode. By default, the sieve\-filter command runs in
+simulation mode in which it changes nothing, meaning that no mailbox is altered
+in any way and no actions are performed. It only prints what would be done.
+Using this option, the sieve\-filter command becomes active and performs the
+requested actions.
+.TP
+.BI \-m\  default\-mailbox
+The mailbox where the (implicit) \fBkeep\fP Sieve action stores messages. This
+is equal to the \fIsource\-mailbox\fP by default. Specifying a different folder
+will have the effect of moving (or copying if \fB\-W\fP is omitted) all kept
+messages to the indicated folder, instead of just leaving them in the
+\fIsource\-mailbox\fP. Refer to the explanation of the \fIsource\-mailbox\fP
+argument for more information on mailbox naming.
+.TP
+.BI \-o\  setting = value
+Overrides the configuration
+.I setting
+from
+.I @pkgsysconfdir@/dovecot.conf
+and from the userdb with the given
+.IR value .
+In order to override multiple settings, the
+.B \-o
+option may be specified multiple times.
+.TP
+.BI \-q\  output\-mailbox\  \fB[not\ implemented\ yet]\fP
+Store outgoing e\-mail into the indicated \fIoutput\-mailbox\fP. By default,
+the sieve\-filter command ignores Sieve actions such as redirect, reject,
+vacation and notify, but using this option outgoing messages can be appended to
+the indicated mailbox. This option has no effect in simulation mode. Flags of
+redirected messages are not preserved.
+.TP
+.BI \-Q\  mail\-command\  \fB[not\ implemented\ yet]\fP
+Send outgoing e\-mail (e.g. as produced by redirect, reject and vacation)
+through the specified program. By default, the sieve\-filter command ignores
+Sieve actions such as redirect, reject, vacation and notify, but using this
+option outgoing messages can be fed to the \fBstdin\fP of an external shell
+command. This option has no effect in simulation mode. Unless you really know
+what you are doing, \fBDO NOT USE THIS TO FEED MAIL TO SENDMAIL!\fP.
+.TP
+.BI \-s\  script\-file\  \fB[not\ implemented\ yet]\fP
+Specify additional scripts to be executed before the main script. Multiple
+\fB\-s\fP arguments are allowed and the specified scripts are executed
+sequentially in the order specified at the command line.
+.TP
+.BI \-u\  user
+Run the Sieve script for the given \fIuser\fP. When omitted, the
+.I command
+will be executed with the environment of the currently logged in user.
+.TP
+.B \-v
+Produce verbose output during filtering.
+.TP
+.B \-W
+Enables write access to the \fIsource\-mailbox\fP. This allows (re)moving the
+messages from the \fIsource\-mailbox\fP, changing their contents, and changing
+the assigned IMAP flags and keywords.
+.TP
+.BI \-x\  extensions
+Set the available extensions. The parameter is a space\-separated list of the
+active extensions. By prepending the extension identifiers with \fB+\fP or
+\fB\-\fP, extensions can be included or excluded relative to the configured set
+of active extensions. If no extensions have a \fB+\fP or \fB\-\fP prefix, only
+those extensions that are explicitly listed will be enabled. Unknown extensions
+are ignored and a warning is produced.
+
+For example \fB\-x\fP \(dq+imapflags \-enotify\(dq will enable the deprecated
+imapflags extension and disable the enotify extension. The rest of the active
+extensions depends on the \fIsieve_extensions\fP and
+\fIsieve_global_extensions\fP settings. By default, i.e.
+when \fIsieve_extensions\fP and \fIsieve_global_extensions\fP remain
+unconfigured, all supported extensions are available, except for deprecated
+extensions or those that are still under development.
+
+.\"------------------------------------------------------------------------
+.SH ARGUMENTS
+.TP
+.I script\-file
+Specifies the Sieve script to (compile and) execute.
+
+Note that this tool looks for a pre\-compiled binary file with a \fI.svbin\fP
+extension and with basename and path identical to the specified script. Use the
+\fB\-C\fP option to disable this behavior by forcing the script to be compiled
+into a new binary.
+.TP
+.I source\-mailbox
+Specifies the source mailbox containing the messages that the Sieve filter will
+act upon.
+
+This is the name of a mailbox, as visible to IMAP clients, except in UTF-8
+format. The hierarchy separator between a parent and child mailbox is commonly
+.RB \(aq / \(aq
+or
+.RB \(aq . \(aq,
+but this depends on your selected mailbox storage format and
+namespace configuration. The mailbox names may also require a namespace prefix.
+
+This mailbox is not modified unless the \fB\-W\fP option is specified.
+.TP
+.I discard\-action
+Specifies what is done with messages in the \fIsource\-mailbox\fP that where not
+kept or otherwise stored by the Sieve script; i.e. those messages that would
+normally be discarded if the Sieve script were executed at delivery.
+The \fIdiscard\-action\fP parameter accepts one of the following values:
+.RS 7
+.TP
+.BR keep\  (default)
+Keep discarded messages in source mailbox.
+.TP
+.BI move\  mailbox
+Move discarded messages to the indicated \fImailbox\fP. This is for instance
+useful to move messages to a Trash mailbox. Refer to the explanation of
+the \fIsource\-mailbox\fP argument for more information on mailbox naming.
+.TP
+.B delete
+Flag discarded messages as \\DELETED.
+.TP
+.B expunge
+Expunge discarded messages, meaning that these are removed irreversibly when the
+tool finishes filtering.
+.RE
+.IP
+When the \fB\-W\fP option is not specified, the \fIsource\-mailbox\fP is
+immutable and the specified \fIdiscard\-action\fP has no effect. This means that
+messages are at most \fIcopied\fP to a new location. In contrast, when the
+\fB\-W\fP is specified, messages that are successfully stored somewhere else by
+the Sieve script are \fBalways\fP expunged from the \fIsource\-mailbox\fP, with
+the effect that these are thus \fImoved\fP to the new location. This happens
+irrespective of the specified \fIdiscard\-action\fP. Remember: only discarded
+messages are affected by the specified \fIdiscard\-action\fP.

+.\"------------------------------------------------------------------------
+.SH DESCRIPTION
+.PP
+The \fBsieve\-test\fP command is part of the Pigeonhole Project
+(\fBpigeonhole\fR(7)), which adds Sieve (RFC 5228) support to the Dovecot
+secure IMAP and POP3 server (\fBdovecot\fR(1)).
+.PP
+Using the \fBsieve\-test\fP command, the execution of Sieve scripts can be
+tested. This evaluates the script for the provided message, yielding a set of
+Sieve actions. Unless the \fB\-e\fP option is specified, it does not actually
+execute these actions, meaning that it does not store or forward the message
+anywere. Instead, it prints a detailed list of what actions would normally take
+place. Note that, even when \fB\-e\fP is specified, no messages are ever
+transmitted to remote SMTP recipients. The outgoing messages are always printed
+to \fBstdout\fP instead.
+.PP
+This is a very useful tool to debug the execution of Sieve scripts. It can be
+used to verify newly installed scripts for the intended behaviour and it can
+provide more detailed information about script execution problems that are
+reported by the Sieve plugin, for example by tracing the execution and
+evaluation of commands and tests respectively.
+.\"------------------------------------------------------------------------
+.SH OPTIONS
+.TP
+.BI \-a\  orig\-recipient\-address
+The original envelope recipient address. This is what Sieve\(aqs envelope test
+will compare to when the \(dqto\(dq envelope part is requested. Some tests and
+actions will also use this as the script owner\(aqs e\-mail address. If this
+option is omitted, the recipient address is retrieved from the
+\(dqEnvelope-To:\(dq, or \(dqTo:\(dq message headers. If none of these headers
+is present either, the recipient address defaults to
+\fIrecipient@example.com\fP.
+.TP

+Sieve compilation.
+.TP
+.B \-D
+Enable Sieve debugging.
+.TP
+.BI \-d\  dump\-file
+Causes a dump of the generated code to be written to the specified file. This is
+identical to the dump produced by \fBsieve\-dump\fR(1). Using \(aq\-\(aq as
+filename causes the dump to be written to \fBstdout\fP.
+.TP
+.BI \-e
+Enables true execution of the set of actions that results from running the
+script. In combination with the \fB\-l\fP parameter, the actual delivery of
+messages can be tested. Note that this will not transmit any messages to remote
+SMTP recipients. Such actions only print the outgoing message to \fBstdout\fP.
+.TP
+.BI \-f\  envelope\-sender
+The envelope sender address (return path). This is what Sieve\(aqs envelope test
+will compare to when the \(dqfrom\(dq envelope part is requested. Also, this is
+where response messages are \(aqsent\(aq to. If this option is omitted, the sender
+address is retrieved from the \(dqReturn-Path:\(dq, \(dqSender:\(dq or
+\(dqFrom:\(dq message headers. If none of these headers is present either,
+the sender envelope address defaults to \fIsender@example.com\fP.
+.TP
+.BI \-l\  mail\-location
+The location of the user\(aqs mail store. The syntax of this option\(aqs
+\fImail\-location\fP parameter is identical to what is used for the
+mail_location setting in the Dovecot config file. This parameter is typically
+used in combination with \fB\-e\fP to test the actual delivery of messages. If
+\fB\-l\fP is omitted when \fB\-e\fP is specified, mail store actions like
+fileinto and keep are skipped.
+.TP
+.BI \-m\  default\-mailbox

+.BI \-r\  recipient\-address
+The final envelope recipient address. Some tests and actions will
+use this as the script owner\(aqs e\-mail address. For example, this is what is
+used by the vacation action to check whether a reply is appropriate. If the
+\fB\-r\fP option is omitted, the original envelope recipient address will be used
+instead (see \fB\-a\fP option for more info).
+.TP
+.BI \-s\  script\-file

+.PP
+Using the \fB\-t\fP option, the \fBsieve\-test\fP tool can be configured to
+print detailed trace information on the Sieve script execution to a file or

+the matched values can be printed.
+.PP
+The runtime trace can be configured using the \fB\-T\fP option, which can be
+specified multiple times. It can be used as follows:
+
+.TP 2
+\fB\-Tlevel=...\fP
+Set the detail level of the trace debugging. One of the following values can
+be supplied:
+.RS 2
+.TP 3

+Only print executed action commands, like keep, fileinto, reject and redirect.
+.TP
+\fIcommands\fP
+Print any executed command, excluding test commands.
+.TP
+\fItests\fP
+Print all executed commands and performed tests.
+.TP
+\fImatching\fP
+Print all executed commands, performed tests and the values matched in those
+tests.
+.RE
+.TP 2
+\fB\-Tdebug\fP
+Print debug messages as well. This is usually only useful for developers and
+is likely to produce messy output.
+.TP
+\fB\-Taddresses\fP
+Print byte code addresses for the current trace output. Normally, only the
+current Sieve source code position (line number) is printed. The byte code
+addresses are equal to those listed in a binary dump produced using the
+\fB\-d\fP option or by the \fBsieve\-dump(1)\fP command.
+.\"------------------------------------------------------------------------
+.SS DEBUG SIEVE EXTENSION
+.PP
+To improve script debugging, this Sieve implementation supports a custom Sieve
+language extension called \(aqvnd.dovecot.debug\(aq. It adds the \fBdebug_log\fP
+command that allows logging debug messages.
+.PP
+Example:
+.PP
+require \(dqvnd.dovecot.debug\(dq;
+.PP
+if header :contains \(dqsubject\(dq \(dqhello\(dq {
+.PP
+  debug_log \(dqSubject header contains hello!\(dq;
+.PP
+}
+.PP
+Tools such as \fBsieve\-test\fP, \fBsievec\fP and \fBsieve\-dump\fP have support
+for the vnd.dovecot.debug extension enabled by default and it is not necessary
+to enable nor possible to disable the availability of the debug extension with
+the \fB\-x\fP option. The logged messages are written to \fBstdout\fP in this
+case.
+
+In contrast, for the actual Sieve plugin for the Dovecot LDA
+(\fBdovecot\-lda\fR(1)) the vnd.dovecot.debug extension needs to be enabled
+explicitly using the \fIsieve_extensions\fP setting. The messages are then
+logged to the user's private script log file. If used in a global script, the
+messages are logged through the default Dovecot logging facility.

+.SH DESCRIPTION
+.PP
+The \fBsievec\fP command is part of the Pigeonhole Project
+(\fBpigeonhole\fR(7)), which adds Sieve (RFC 5228) support to the Dovecot
+secure IMAP and POP3 server (\fBdovecot\fR(1)).
+.PP
+Using the \fBsievec\fP command, Sieve scripts can be compiled into a binary
+representation. The resulting binary can be used directly to process e\-mail
+messages during the delivery process. The delivery of mail messages and \- by
+means of the LDA Sieve plugin \- also the execution of Sieve scripts is
+performed by Dovecot\(aqs local delivery agent (LDA) called \fBdovecot\-lda\fP(1).
+Usually, it is not necessary to compile the Sieve script manually using
+\fBsievec\fP, because \fBdovecot\-lda\fP will do this automatically if the binary
+is missing. However, in some cases \fBdovecot\-lda\fP does not have permission to
+write the compiled binary to disk, forcing it to recompile the script every time
+it is executed. Using the \fBsievec\fP tool, this can be performed manually by
+an authorized user to increase performance.
+.PP
+The Pigeonhole Sieve implementation recognizes files with a \fB.sieve\fP
+extension as Sieve scripts and corresponding files with a \fB.svbin\fP extension
+as the associated compiled binary. This means for example that Dovecot\(aqs LDA
+process will first look for a binary file \(dqdovecot.svbin\(dq when it needs to
+execute \(dqdovecot.sieve\(dq. It will compile a new binary when it is missing
+or outdated.
+.PP
+The \fBsievec\fP command is also useful to verify Sieve scripts before using.
+Additionally, with the \fB\-d\fP option it can output a textual (and thus
+human\-readable) dump of the generated Sieve code to the specified file. The
+output is then identical to what the \fBsieve\-dump\fP(1) command produces for a
+stored binary file. This output is mainly useful to find bugs in the compiler
+that yield corrupt binaries.

+imapflags extension and disable the enotify extension. The rest of the active
+extensions depends on the \fIsieve_extensions\fP and
+\fIsieve_global_extensions\fP settings. By default, i.e.
+when \fIsieve_extensions\fP and \fIsieve_global_extensions\fP remain
+unconfigured, all supported extensions are available, except for deprecated
+extensions or those that are still under development.

+.\"------------------------------------------------------------------------
+.SH ARGUMENTS
+.TP
+.I script\-file
+Specifies the script to be compiled. If the \fIscript\-file\fP argument is a
+directory, all files in that directory with a \fI.sieve\fP extension are
+compiled into a corresponding \fI.svbin\fP binary file. The compilation is not
+halted upon errors; it attempts to compile as many scripts in the directory as
+possible. Note that the \fB\-d\fP option and the \fIout\-file\fP argument are
+not allowed when the \fIscript\-file\fP argument is a directory.
+.TP
+.I out\-file
+Specifies where the (binary) output is to be written. This argument is optional.
+If this argument is omitted, a binary compiled from <scriptname>.sieve is saved
+as <scriptname>.svbin. If this argument is omitted and \fB\-b\fP is specified,
+the binary dump is output to \fBstdout\fP.

+.TP 4
+.B 0
+Compile was successful. (EX_OK, EXIT_SUCCESS)
+.TP
+.B 1

+IMAP FILTER Sieve plugin for Pigeonhole
+
+Relevant specifications
+=======================
+
+	doc/rfc/draft-bosch-imap-filter-sieve-00.txt
+
+Introduction
+============
+
+Normally, Sieve filters can either be applied at initial mail delivery or
+triggered by certain events in the Internet Message Access Protocol (IMAPSIEVE;
+RFC 6785). The user can configure which Sieve scripts to run at these instances,
+but it is not possible to trigger the execution of Sieve scripts manually.
+However, this could be very useful; e.g, to test new Sieve rules and to
+re-filter messages that were erroneously handled by an earlier version of the
+Sieve scripts involved.
+
+Pigeonhole provides the imap_filter_sieve plugin, which provides a vendor-
+defined IMAP extension called "FILTER=SIEVE". This adds a new "FILTER" command
+that allows applying a mail filter (a Sieve script) on a set of messages that
+match the specified searching criteria.
+
+This plugin is experimental and the specification is likely to change.
+
+Configuration
+=============
+
+The IMAP FILTER Sieve plugin is activated by adding it to the mail_plugins
+setting for  the imap protocol:
+
+protocol imap {
+	mail_plugins = $mail_plugins imap_filter_sieve
+}
+
+Currently, no other settings specific to this plugin are defined. It uses the
+normal configuration settings used by the LDA Sieve plugin at delivery.
+
+The sieve_before and sieve_after scripts are currently ignored by this plugin.
+
+Example
+-------
+
+protocol imap {
+  # Space separated list of plugins to load (default is global mail_plugins).
+  mail_plugins = $mail_plugins imap_filter_sieve
+}
+
+plugin {
+  sieve_global = /usr/lib/dovecot/sieve-global.d
+}

+IMAPSIEVE plugins for Pigeonhole
+
+Relevant specifications
+=======================
+
+	doc/rfc/imapsieve.rfc6785.txt
+
+Introduction
+============
+
+As defined in the base specification, the Sieve language is used only during
+delivery. However, in principle, it can be used at any point in the processing
+of an email message. RFC 6785 defines the use of Sieve filtering in IMAP,
+operating when messages are created or their attributes are changed. This
+feature extends both Sieve and IMAP. Therefore, Pigeonhole provides both an
+IMAP and a Sieve plugin. The IMAP plugin is called "imap_sieve" and the Sieve
+plugin is called "sieve_imapsieve".
+
+The basic IMAPSIEVE capability allows attaching a Sieve script to a mailbox
+(or any mailbox) by setting a special IMAP METADATA entry. This way, users can
+configure Sieve scripts that are run for IMAP events in their mailboxes. The
+Pigeonhole implementation also adds the ability for administrators to configure
+Sieve scripts outside the user's control, that are run either before or after a
+user's script if there is one.
+
+Dovecot-specific Environment Items
+==================================
+
+The "imapsieve" extension defined in RFC 6785 defines additional environment
+items for the "environment" extension defined in RFC 5183. Beyond those, Dovecot
+defines a few more. These are available when the Dovecot-specific
+"vnd.dovecot.imapsieve" extension is enabled using the "require" command. The
+"vnd.dovecot.imapsieve" extension implicitly uses the "imapsieve" extension, so
+that extension does not need to be enabled as well in that case. The following
+Dovecot-specific environment items are added:
+
+vnd.dovecot.mailbox-from
+  The mailbox where the message is being copied or moved from (the source
+  mailbox). This environment item is only set when the Sieve script is executed
+  from an IMAP COPY or MOVE command.
+
+vnd.dovecot.mailbox-to
+  The mailbox where the message is being copied to (the destination mailbox).
+  If the Sieve script is not executed from an IMAP COPY or MOVE command, this
+  environment is always equal to the "imap.mailbox" environment item. Otherwise,
+  the "imap.mailbox" item points to the mailbox where the Sieve script is
+  executing for, which may actually be the source mailbox (see the
+  imapsieve_mailboxXXX_copy_source_after setting).
+
+Configuration
+=============
+
+The IMAP plugin is activated by adding it to the mail_plugins setting for 
+the imap protocol:
+
+protocol imap {
+	mail_plugins = $mail_plugins imap_sieve
+}
+
+This only will enable support for administrator scripts. User scripts are only
+supported when additionally a Sieve URL is configured using the imapsieve_url
+plugin setting. This URL points to the ManageSieve server that users need to use
+to upload their Sieve scripts. This URL will be shown to the client in the IMAP
+CAPABILITY response as IMAPSIEVE=<URL>.
+
+The Sieve plugin is activated by adding it to the sieve_plugins setting:
+
+sieve_plugins = sieve_imapsieve
+
+This plugin registers the "imapsieve" extension with the Sieve interpreter. This
+extension is enabled implicitly, which means that it does not need to be added
+to the "sieve_extensions" setting.
+
+Note that the "imapsieve" extension can only be used from IMAP. When it is used
+in the active delivery script, it will cause runtime errors. To make a Sieve
+script suitable for both delivery and IMAP, the availability of the extension
+can be tested using the "ihave" test (RFC 5463) as usual.
+
+The following settings are recognized the "imap_sieve" plugin:
+
+imapsieve_url =
+  If configured, this setting enables support for user Sieve scripts in IMAP.
+  So, leave this unconfigured if you don't want users to have the ability to
+  associate Sieve scripts with mailboxes. The value is an URL pointing to the
+  ManageSieve server that users must use to upload their Sieve scripts. 
+
+imapsieve_mailboxXXX_name =
+  This setting configures the name of a mailbox for which administrator scripts
+  are configured. The `XXX' in this setting is a sequence number, which allows
+  configuring multiple associations between Sieve scripts and mailboxes. The 
+  settings defined hereafter with matching sequence numbers apply to the mailbox
+  named by this setting. The sequence of configured mailboxes ends at the first
+  missing "imapsieve_mailboxXXX_name" setting. This setting supports wildcards
+  with a syntax compatible with the IMAP LIST command, meaning that this
+  setting can apply to multiple or even all ("*") mailboxes.
+
+imapsieve_mailboxXXX_before =
+imapsieve_mailboxXXX_after =
+  When an IMAP event of interest occurs, these sieve scripts are executed before
+  and after any user script respectively. These settings each specify the
+  location of a single sieve script. The semantics of these settings are very
+  similar to the "sieve_before" and "sieve_after" settings: the specified
+  scripts form a sequence together with the user script in which the next script
+  is only executed when an (implicit) keep action is executed.
+
+imapsieve_mailboxXXX_causes =
+  Only execute the administrator Sieve scripts for the mailbox configured with
+  "imapsieve_mailboxXXX_name" when one of the listed IMAPSIEVE causes apply.
+  This has no effect on the user script, which is always executed no matter the
+  cause.
+
+imapsieve_mailboxXXX_from =
+  Only execute the administrator Sieve scripts for the mailbox configured with
+  "imapsieve_mailboxXXX_name" when the message originates from the indicated
+  mailbox. This setting supports wildcards with a syntax compatible with the
+  IMAP LIST command
+
+imapsieve_mailboxXXX_copy_source_after =
+  When the cause is "COPY", run the specified Sieve script for the message in
+  the source mailbox after the Sieve script for the corresponding message in the
+  destination mailbox successfully finishes executing . This does not apply to
+  moved messages, since the message is removed from the source mailbox in that
+  case.
+
+imapsieve_expunge_discarded=no
+  When enabled, discarded messages (for which no keep action is in effect) will
+  be expunged immediately when the Sieve script execution is succcessful.
+  Normally, such messages are only marked with the "\Deleted" flag and will be
+  expunged only when the client explicitly issues an IMAP EXPUNGE command on the
+  mailbox at a later time.
+
+Example
+-------
+
+protocol imap {
+  # Space separated list of plugins to load (default is global mail_plugins).
+  mail_plugins = $mail_plugins imap_sieve
+}
+
+plugin {
+  sieve_plugins = sieve_imapsieve
+
+  imapsieve_url = sieve://sieve.example.org
+
+  # From elsewhere to Spam folder
+  imapsieve_mailbox1_name = Spam
+  imapsieve_mailbox1_causes = COPY
+  imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve
+  # From Spam folder to elsewhere
+  imapsieve_mailbox2_name = *
+  imapsieve_mailbox2_from = Spam
+  imapsieve_mailbox2_causes = COPY
+  imapsieve_mailbox2_before = file:/usr/lib/dovecot/sieve/report-ham.sieve

+Sieve Extprograms plugin for Pigeonhole
+
+Relevant specifications
+=======================
+
+	doc/rfc/spec-bosch-sieve-extprograms.txt
+
+Introduction
+============
+
+Sieve (RFC 5228) is a highly extensible machine language specifically tailored
+for internet message filtering. For the Dovecot Secure IMAP server, Sieve
+support is provided by the Pigeonhole Sieve plugin. This package includes a
+plugin for Pigeonhole called "sieve_extprograms", which extends the Sieve 
+filtering implementation with action commands for invoking a predefined set of
+external programs. Messages can be piped to or filtered through those programs
+and string data can be input to and retrieved from those programs.
+
+The Sieve language is explicitly designed to be powerful enough to be useful yet
+limited in order to allow for a safe server-side filtering system. Therefore,
+the base specification of the language makes it impossible for users to do
+anything more complex (and dangerous) than write simple mail filters. One of the
+consequences of this security-minded design is that users cannot execute
+external programs from their mail filter. Particularly for server-side filtering
+setups in which mail accounts have no corresponding system account, allowing the
+execution of arbitrary programs from the mail filter can be a significant
+security risk. However, such functionality can also be very useful, for instance
+to easily implement a custom action or external effect that Sieve normally
+cannot provide.
+
+The "sieve_extprograms" plugin provides an extension to the Sieve filtering
+language adding new action commands for invoking a predefined set of external
+programs. To mitigate the security concerns, the external programs cannot be
+chosen arbitrarily; the available programs are restricted through administrator
+configuration.
+
+This extension is specific to the Pigeonhole Sieve implementation for the
+Dovecot Secure IMAP server. It will therefore most likely not be supported by
+web interfaces or GUI-based Sieve editors. This extension is primarily meant for
+use in small setups or global scripts that are managed by the systems
+administrator.
+
+Implementation Status
+---------------------
+
+The "vnd.dovecot.pipe", "vnd.dovecot.filter" and "vnd.dovecot.execute" Sieve
+language extensions introduced by this plugin are vendor-specific with draft
+status and their implementation for Pigeonhole is experimental, which means that
+the language extensions are still subject to change and that the current
+implementation is not thoroughly tested.
+
+Configuration
+=============
+
+The plugin is activated by adding it to the sieve_plugins setting:
+
+sieve_plugins = sieve_extprograms
+
+This plugin registers the "vnd.dovecot.pipe", "vnd.dovecot.filter" and
+"vnd.dovecot.execute" extensions with the Sieve interpreter. However, these
+extensions are not enabled by default and thus need to be enabled explicitly. It
+is recommended to restrict the use of these extensions to global context by
+adding these to the "sieve_global_extensions" setting. If personal user scripts
+also need to directly access external programs, the extensions need to be added
+to the "sieve_extensions" setting. 
+
+The commands introduced by the Sieve language extensions in this plugin can
+directly pipe a message or string data to an external program (typically a shell
+script) by forking a new process. Alternatively, these can connect to a unix
+socket behind which a Dovecot script service is listening to start the external
+program, e.g. to execute as a different user or for added security.
+
+The program name specified for the new Sieve "pipe", "filter" and "execute"
+commands is used to find the program or socket in a configured directory.
+Separate directories are specified for the sockets and the directly executed
+binaries. The socket directory is searched first. Since the use of "/" in
+program names is prohibited, it is not possible to build a hierarchical
+structure.
+
+Directly forked programs are executed with a limited set of environment
+variables: HOME, USER, HOST, SENDER, RECIPIENT and ORIG_RECIPIENT. Programs
+executed through the script-pipe socket service currently have no environment
+set at all.
+
+If a shell script is expected to read a message or string data, it must fully
+read the provided input until the data ends with EOF, otherwise the Sieve action
+invoking the program will fail. The action will also fail when the shell script
+returns a nonzero exit code. Standard output is available for returning a
+message (for the filter command) or string data (for the execute command) to the
+Sieve interpreter. Standard error is written to the LDA log file. 
+
+The three extensions introduced by this plugin - "vnd.dovecot.pipe",
+"vnd.dovecot.filter" and "vnd.dovecot.pipe" - each have separate but similar
+configuration. The settings that specify a time period are specified in
+s(econds), unless followed by a d(ay), h(our) or m(inute) specifier character.
+The following configuration settings are used, for which "<extension>" in the
+setting name is replaced by either "pipe", "filter" or "execute" depending on
+which extension is being configured.
+
+sieve_<extension>_socket_dir =
+  Points to a directory relative to the Dovecot base_dir where the plugin looks
+  for script service sockets. 
+
+sieve_<extension>_bin_dir =
+  Points to a directory where the plugin looks for programs (shell scripts) to
+  execute directly and pipe messages to.
+
+sieve_<extension>_exec_timeout = 10s
+  Configures the maximum execution time after which the program is forcibly
+  terminated.
+
+sieve_<extension>_input_eol = crlf
+  Determines the end-of-line character sequence used for the data piped to
+  external programs. The default is currently "crlf", which represents a
+  sequence of the carriage return (CR) and line feed (LF) characters. This
+  matches the Internet Message Format (RFC5322) and what Sieve itself uses as a
+  line ending. Set this setting to "lf" to use a single LF character instead.
+
+Examples
+--------
+
+Example 1: socket service for "pipe" and "execute"
+
+plugin {
+  sieve = ~/.dovecot.sieve
+
+  sieve_plugins = sieve_extprograms
+  sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.execute
+
+  # pipe sockets in /var/run/dovecot/sieve-pipe
+  sieve_pipe_socket_dir = sieve-pipe        
+
+  # execute sockets in /var/run/dovecot/sieve-execute
+  sieve_execute_socket_dir = sieve-execute
+}
+
+service sieve-pipe-script {
+  # This script is executed for each service connection
+  executable = script /usr/lib/dovecot/sieve-extprograms/sieve-pipe-action.sh
+
+  # use some unprivileged user for execution
+  user = dovenull
+
+  # socket name is program-name in Sieve (without sieve-pipe/ prefix)
+  unix_listener sieve-pipe/sieve-pipe-script {
+  }
+}
+
+service sieve-execute-action {
+  # This script is executed for each service connection
+  executable = script /usr/lib/dovecot/sieve-extprograms/sieve-execute-action.sh
+
+  # use some unprivileged user for execution
+  user = dovenull
+
+  # socket name is program-name in Sieve (without sieve-execute/ prefix)
+  unix_listener sieve-execute/sieve-execute-action {
+  }
+}
+
+Example 2: direct execution for "pipe" and "filter"
+
+plugin {
+  sieve = ~/.dovecot.sieve
+
+  sieve_plugins = sieve_extprograms
+  sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter
+
+  # This directory contains the scripts that are available for the pipe command.
+  sieve_pipe_bin_dir = /usr/lib/dovecot/sieve-pipe
+
+  # This directory contains the scripts that are available for the filter
+  # command.
+  sieve_filter_bin_dir = /usr/lib/dovecot/sieve-filter
+}

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.
+usage='$progpath [OPTION]...'
+
+# Short help message in response to '-h' and '--help'.  Add to this or
+# override it after sourcing this library to reflect the full set of
+# options your script accepts.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.

+/* FIXME: (from draft RFC)
+ 
+   Header/envelope tests [Sieve] together with Sieve variables can be used to
+   extract the list of users to receive notifications from the incoming email
+   message or its envelope. This is potentially quite dangerous, as this can be
+   used for Deny Of Service attacks on recipients controlled by the message
+   sender. For this reason implementations SHOULD NOT allow use of variables
+   containing values extracted from the email message in the method parameter to
+   the notify action.  Note that violation of this SHOULD NOT may result in* the
+   creation of an open relay, i.e. any sender would be able to create specially
+   crafted email messages that would result in notifications delivered to
+   recipients under the control of the sender. In worst case this might result
+   in financial loss by user controlling the Sieve script and/or by recipients
+   of notifications (e.g. if a notification is an SMS message).
+
+   --> This is currently not possible to check.

+/* Variable Substitution
+ * ---------------------
+ *
+ * The variable strings are preprocessed into an AST list consisting of variable
+ * substitutions and constant parts of the string. The variables to which
+ * the substitutions link are looked up and their index in their scope storage
+ * is what is added to the list and eventually emitted as byte code. So, in
+ * bytecode a variable string will look as a series of substrings interrupted by
+ * integer operands that refer to variables. During execution, the strings and
+ * the looked-up variables are concatenated to obtain the desired result. The
+ * the variable references are simple indexes into an array of variables, so
+ * looking these up during execution is a trivial process.
+ *
+ * However (RFC 5229):
+ *   Tests or actions in future extensions may need to access the
+ *   unexpanded version of the string argument and, e.g., do the expansion
+ *   after setting variables in its namespace.  The design of the
+ *   implementation should allow this.
+ *
+ * Various options exist to provide this feature. If the extension is entirely
+ * namespace-based there is actually not very much of a problem. The variable
+ * list can easily be extended with new argument-types that refer to a variable
+ * identifier instead of an index in the variable's storage.

+ * -------------------
+ *
+ * Authors: Stephan Bosch
+ * Specification: vendor-specific
+ *   (FIXME: provide specification for test authors)
+ *
+ */
+
+/*
+ * Purpose: This custom extension is used to add sieve commands and tests that
+ *          act the Sieve engine and on the test suite itself. This practically
+ *          provides the means to completely control and thereby test the Sieve
+ *          compiler and interpreter. This extension transforms the basic Sieve
+ *          language into something much more powerful and suitable to perform
+ *          complex self-test operations. Of course, this extension is only
+ *          available (as vnd.dovecot.testsuite) when the sieve engine is used
+ *          from within the testsuite commandline tool. Test scripts have the
+ *          extension .svtest by convention to distinguish them from any normal
+ *          sieve scripts that may reside in the same directory.
+ *
+ * WARNING: Although this code can serve as an example on how to write
+ *          extensions to the Sieve interpreter, it is generally _NOT_ to be
+ *          used as a source for ideas on new Sieve extensions. Many of the
+ *          commands and tests that this extension introduces conflict with the
+ *          goal and the implied restrictions of the Sieve language. These
+ *          restrictions were put in place with good reason. Therefore, do
+ *          _NOT_ export functionality provided by this testsuite extension to
+ *          your custom extensions that are to be put to general use.
