+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
+}

+  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.

+.\"------------------------------------------------------------------------
+.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 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 SYNOPSIS
+.B sieve\-test
+.RI [ options ]
+.I script\-file
+.I mail\-file
+.\"------------------------------------------------------------------------
+.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
+.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\-test\fP and its

+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
+The mailbox where the keep action stores the message. This is \(dqINBOX\(dq
+by default.
+.TP
+.BI \-o\  setting = value

+option may be specified multiple times.
+.TP
+.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).

+.SH USAGE
+.SS RUNTIME TRACE DEBUGGING
+.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
+standard output. For example, the encountered commands, the performed tests and
+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
+\fIactions\fP (default)
+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 SYNOPSIS
+.B sievec
+.RI [ options ]
+.I script\-file
+.RI [ out\-file ]
+.\"------------------------------------------------------------------------
+.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.
+.\"------------------------------------------------------------------------
+.SH OPTIONS
+.TP
+.BI \-c\  config\-file
+Alternative Dovecot configuration file path.
+.TP
+.B \-d
+Don\(aqt write the binary to \fIout\-file\fP, but write a textual dump of the
+binary instead. In this context, the \fIout\-file\fP value '\-' has special
+meaning: it causes the the textual dump to be written to \fBstdout\fP.
+The \fIout\-file\fP argument may also be omitted, which has the same effect
+as '\-'.
+The output is identical to what the \fBsieve\-dump\fP(1) command produces
+for a compiled Sieve binary file. Note that this option is not allowed when the
+\fIout\-file\fP argument is a directory.
+.TP
+.B \-D
+Enable Sieve debugging.
+.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 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.
+.\"------------------------------------------------------------------------

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

+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
+}
