The second main part is an attempt to bring this up-to-date, +using information from ChangeLog and git. + +Names may well occur more than once. + +There was a five year gap. It is unlikely that this file is complete. +If you contributed and are not listed, then *please* let us know. Even if you +don't much care, we want to acknowledge your help.

I am going to try to do better +in the future by keeping a record in this file.

Some regular contributors may appear in both. + +I'm going to record people who send in actual patches or who help in detailed +ways. I'm not going to list people who just make a suggestion or report a +bug.

There is no copyright assignment +policy; if you offer a patch, it is assumed to be under the GPL, of whichever +version the main developers see fit to use. + +Mistakes or inadequacies in the documentation are treated as bugs. The main +documentation is called "The Exim Specification" for a reason. So if you +can't code there are still places where your help will be very appreciated. + +General discussion, requests for help, and initial "is this a bug?" questions +go to . Many suspected bugs turn out to not be bugs, so +asking first is appreciated. + +Our main website is at http://www.exim.org/ and contains links to our wiki, +where many frequent setups are walked through. You will also find our +bug-tracking system linked there. + +Development takes place in part on exim-users, when bugs or missing features +are spotted based on feedback from people actually using the product. In +large part, discussion takes place on . While you can use +the bug-tracking system, everyone working on Exim, a mail transfer agent, is +comfortable dealing with just email too, so you can use whichever you're most +comfortable with. + +If you have an idea for a new feature, please do raise it on exim-users first. + +Our code is maintained in a Git repository. The master repository, together +with some others, can be found on http://git.exim.org/ and we welcome patches, +whether of documentation or of code. If you have a request for a new feature +and can accompany it with working code, then it stands a much greater chance +of being incorporated in a timely manner. + +If you're planning on working on a major new feature or redesign, please do +talk to us first. + +We do not have a formal code-review process, but posted patches are subject to +being reworked before being pulled in, or requests for modification made; +we're a small enough pool of developers that we rely on the good judgement and +discretion of the committer rather than formal process. + +We prefer new features to be accompanied by documentation patches, but if no +new documentation is provided, we can write it and, in the process, perhaps +uncover issues to work over with you. Note that the PDF form of the +documentation is faster to build than the TXT form. + +We do have a test harness and appreciate it if new features can be accompanied +by new tests; if this is awkward for you, please do include sufficient +description to allow someone else to write the test. + + +-The Exim Maintainers + July 7th, 2010 diff --git a/LICENCE b/LICENCE new file mode 100644 index 0000000..31d076d --- /dev/null +++ b/LICENCE @@ -0,0 +1,340 @@ + GNU GENERAL PUBLIC LICENSE + Version 2, June 1991 + + Copyright (C) 1989, 1991 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. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, 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 or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +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 give any other recipients of the Program a copy of this License +along with the Program. + +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 Program or any portion +of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +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 Program, 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 Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) 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; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, 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 executable. However, as a +special exception, the source code 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. + +If distribution of executable or 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 counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program 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. + + 5. 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 Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program 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 to +this License. + + 7. 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 Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program 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 Program. + +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. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program 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. + + 9. The Free Software Foundation may publish revised and/or new versions +of the 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 Program +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 Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, 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 + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), 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 Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. 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. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program 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.

The normal configuration options that apply +independently of the operating system are specified by creating files in the +Local directory, as described in chapter 4 of the manual. + +These notes cover the os.* files in the OS directory, and contain information +for people who want to port the program to some new OS, or to modify the +configuration for an existing port. If you are just wanting to compile Exim on +a system that it already knows about, you do not need to read further unless +there are problems. + +The os.c- files +----------------------- + +There may be an os.c- file for each operating system, but for many of +them it is not necessary. No error occurs is there isn't one. There is a +generic file called os.c which contains code that is common to two or more OS +for setting a restarting or a non-restarting signal, for computing the load +average, and for finding all the network interface addresses. A few OS have +their own individual code for one or more of these. When they do, the code is +put into an os.c- file, which also defines a macro such as +OS_RESTARTING_SIGNAL (for example) to cut out the common code in the generic +os.c. + +The os.h- files +----------------------- + +For each OS that Exim knows about, there is an os.h- file, where + is the OS name. The relevant file is included as a C header file for +all Exim compilation by pointing a symbolic link called os.h at it from the +build directory. The settings are as follows: + +The select() function +--------------------- + +There is a difference in the data type for the second argument to the select() +function in some OS. The macro SELECT_ARG2_TYPE can be used to define the type. +If it is not defined in os.h, then it is defaulted to fs_set in exim.h. + +The dn_expand() function +------------------------ + +There is a difference in the data type for the fourth argument to the +dn_expand() function in some OS. The macro DN_EXPAND_ARG4_TYPE can be used to +define the type. If it is not defined in os.h, then it is defaulted to char * +in exim.h. + +The h_errno variable +-------------------- + +If NEED_H_ERRNO is defined, then a definition of the form + +extern int h_errno + +is included in the compiled code of Exim. + +The strerror() function +----------------------- + +Most systems provide the ANSI standard strerror() function; older systems may +instead have an errlist[] variable in which to look up error texts. Defining +STRERROR_FROM_ERRLIST causes Exim to build its own strerror() function that +mimics the ANSI function by lookup up the error code in errlist. + +Truncating files +---------------- + +The fcntl() option for truncating the length of a file is called F_FREESP in +most systems; in some, however, it is called O_TRUNC. Some os.h files define +F_FREESP to be O_TRUNC for this reason. + +Finding local interfaces +------------------------ + +The SIOCGIFCONF ioctl for finding local interfaces behaves differently on BSD +systems. It returns a vector of ifreq blocks containing sockaddr structures +that can be longer than their sizeof definition, making the returned ifreq +blocks longer than their sizeof definitions. BSD sockaddrs structures contain +an sa_len field giving the actual size. To cope with difference, there is a +macro called HAVE_SA_LEN. If it is defined, code that works on BSD systems is +used. Otherwise, the objects returned by SIOCGIFCONF are assumed to be of +length sizeof(struct ifreq). + +On some operating systems, the SIOCGIFCONF ioctl returns the IP addresses +with the list of interfaces, and there is no need to call SIOCGIFADDR for each +individual address. Mostly, making the second call does no harm, but on Linux +when there are IP aliases, it causes things to go wrong. This also happens on +BSDI and GNU Hurd. Therefore, there is now a macro to cut it out, called +SIOCGIFCONF_GIVES_ADDR. + +Note that, if IPv6 support is configured, Exim cannot find the IPv6 addresses +on local interfaces by itself. You need to set the local_interfaces option in +this situation. + +Computing load averages +----------------------- + +There are several different ways that load averages are computed. One-off code +is put in the os.c-, but several OS use similar methods, and these +are coded in the generic os.c, using a number of parameters to make variations +between OS. + +Sometimes the load average is not available to unprivileged callers. If +LOAD_AVG_NEEDS_ROOT is set, Exim ensures that it is root before trying to +obtain a load average value. + +(1) If HAVE_BSD_GETLOADAVG is defined, Exim uses a simple call to the +getloadavg() function. + +(2) If HAVE_KSTAT is defined, Exim uses the kstat package as found in Solaris 2 +(but nowhere else as yet). It uses some supplementary definitions: + + LOAD_AVG_KSTAT the kstat to use + LOAD_AVG_KSTAT_MODULE the module to access + LOAD_AVG_KSTAT_SYMBOL the symbol containing the value we want + LOAD_AVG_KSTAT_FIELD the field identity + +(3) If HAVE_DEV_KMEM is defined, Exim reads load average values from the +/dev/kmem device. It uses some supplementary definitions: + + LOAD_AVG_TYPE the data type + LOAD_AVG_SYMBOL the symbol to look up + KERNEL_PATH the name of the kernel + FSCALE a scaling factor + +Sometimes FSCALE is defined in system headers so need not be defined in the +os.h- file. + +Glibc systems and IP options +---------------------------- + +The code for inspecting IP options is the same in all OS except for systems +using glibc (e.g. Linux), which uses a different structure to return data from +getsockopt(). To handle this, there is a macro called + + GLIBC_IP_OPTIONS + +which should be set for Linux (in os.h-Linux) and any other operating system +that uses glibc. + +Options for statvfs() +--------------------- + +The following settings apply to the compilation of the Exim monitor as well as +to the main Exim binary. + +#undefine HAVE_STATFS + +Exim has options for checking the amount of space in the spool partition +before accepting a message, and the monitor has the ability to display a +stripchart of the percentage fullness of a particular disc partition, usually +/var/spool/mail. The standard way of finding out the data is to call the +statvfs() function, but some operating systems use statfs() and some may not +have the ability at all. The Exim code uses STATVFS() for this function and +this gets defined appropriately. HAVE_STATFS is defined before including the +os.h file; undefining it suppresses the code for checking a partition in the +main binary, and for monitoring disc partition in the monitor. + +When HAVE_STATFS is defined, the distinction between statvfs() and statfs() is +made by checking HAVE_SYS_STATVFS_H. If it is defined, then sys/statvfs.h is +included. Otherwise, STATVFS() is defined as a macro for statfs(), and some +further includes are done, according to the following definitions: + +#define HAVE_SYS_MOUNT_H +#define HAVE_VFS_H + +Each of those definitions causes the inclusion of the corresponding system +header file in the Exim monitor compilation. For example, the first one causes + +#include + +to be obeyed. Different systems may require different combinations of these +headers. + +The sys/resource.h header +------------------------- + +One OS does not have the sys/resource.h header. If NO_SYS_RESOURCE_H is defined +in an os.h- file, then the #include for this header is skipped in +exim.h. + +Support for login_cap functions +------------------------------- + +Some of the BSD systems support functions for controlling the resources that +user processes can use (e.g. login_getpwclass). If HAVE_SETCLASSRESOURCES is +defined, Exim supports this feature for running pipe deliveries, using the +setclassresources() function. + +The crypt_h header +------------------ + +Some OS require crypt.h to be included to get a prototype for the crypt() +function. This is needed only when compiling with AUTH support. If CRYPT_H is +defined, then this header is included. + +mmap() support +-------------- + +The CDB support includes the option of handling file operations by using +mmap()/munmap(). This gives a reasonable performance increase which will +probably scale over multiple processes (since the files are mapped read-only +shared). The vast majority of modern operating systems will support mmap +(certainly in the simplified way that it is being used here). For example any +BSD 4.x derived or POSIX compliant system will support it, as will pretty much +any system using dynamically shared link libraries. + +If the OS is believed to support mmap() then the symbol HAVE_MMAP is defined. +Not all systems that support mmap will have had their config files updated to +reflect this. Currently Linux, Sun, BSD and SGI/mips systems have been updated. + +*** End *** diff --git a/OS/os.c-FreeBSD b/OS/os.c-FreeBSD new file mode 100644 index 0000000..d65a789 --- /dev/null +++ b/OS/os.c-FreeBSD @@ -0,0 +1,50 @@ +/************************************************* +* Exim - an Internet mail transport agent * +*************************************************/ + +/* Copyright (c) Jeremy Harris 1995 - 2020 */ +/* Copyright (c) The Exim Maintainers 2021 */ +/* SPDX-License-Identifier: GPL-2.0-or-later */ +/* See the file NOTICE for conditions of use and distribution. */ + +/* FreeBSD-specific code.

This is the official guide for Exim 4. +The current edition covers release 4.10 and a few later extensions. + +The O'Reilly book about Exim ("Exim The Mail Transfer Agent" by Philip Hazel) +covers Exim 3, which is now deprecated. Exim 4 has a large number of changes +from Exim 3, though the basic structure and philosophy remains the same. The +older book may be helpful for the background, but a lot of the detail has +changed, so it is likely to be confusing to newcomers. + +There is a website at https://www.exim.org; this contains details of the +mailing list exim-users@exim.org. + +A copy of the Exim FAQ should be available from the same source that you used +to obtain the Exim distribution. Additional formats for the documentation +(PostScript, PDF, Texinfo, and HTML) should also be available there. + + +EXIM DISTRIBUTION +----------------- + +Unpacking the tar file should produce a single directory called exim-, +containing the following files and directories: + +ACKNOWLEDGMENTS some acknowledgments +CHANGES a conventional file name; it indirects to some files in doc/ +LICENCE the GNU General Public Licence +Local/ an empty directory for local configuration files +Makefile top level Makefile +NOTICE notice about conditions of use +OS/ directory containing OS-specific files +README this file +README.UPDATING special notes about updating from previous versions +doc/ directory of documentation files +exim_monitor/ directory of source files for the Exim monitor +scripts/ directory of scripts used in the build process +src/ directory of source files +util/ directory of independent utilities + +Please see the documentation files for full instructions on how to build, +install, and run Exim. For straightforward installations on operating systems +to which Exim has already been ported, the building process is as follows: + +. Ensure that the top-level Exim directory (e.g. exim-4.80) is the current + directory (containing the files and directories listed above). + +. Edit the file called src/EDITME and put the result in a new file called + Local/Makefile. There are comments in src/EDITME telling you what the various + parameters are. You must at least provide values for BIN_DIRECTORY, + CONFIGURE_FILE, EXIM_USER and EXIM_GROUP (if EXIM_USER is numeric), and it is + recommended that SPOOL_DIRECTORY also be defined here if it is a fixed path. + +. There are a number of additional parameters whose defaults can also be + overridden by additions to Local/Makefile. The basic defaults are in + OS/Makefile-Default, but these settings are overridden for some operating + systems by values on OS/Makefile-. The most commonly-required change + is probably the setting of CC, which defines the command to run the C + compiler, and which defaults to gcc. To change it to cc, add the following + line to Local/Makefile: + + CC=cc + + If you are running the Berkeley DB package as your dbm library, then it is + worth putting USE_DB=yes in Local/Makefile, to get Exim to use the native + interface. This is the default for some operating systems. See + doc/dbm.discuss.txt for discussion on dbm libraries. + +. If you want to compile the Exim monitor, edit the file called + exim_monitor/EDITME and put the result in a file called Local/eximon.conf. + If you are not going to compile the Exim monitor, you should have commented + out the line starting EXIM_MONITOR= when creating Local/Makefile. There are + comments in exim_monitor/EDITME about the values set therein, but in this + case everything can be defaulted if you wish. + +. If your system is not POSIX compliant by default, then you might experience + fewer problems if you help point the build tools to the POSIX variants. For + instance, on Solaris: + + PATH=/usr/xpg4/bin:$PATH make SHELL=/usr/xpg4/bin/sh + +. Type "make". This will determine what your machine's architecture and + operating system are, and create a build directory from those names (e.g. + "build-SunOS5-sparc"). Symbolic links are created from the build directory + to the source directory. A configured make file called /makefile + is then created, and "make" then goes on to use this to build various + binaries and scripts inside the build directory. + +. Type "make install", while running as root, to install the binaries, + scripts, and a default configuration file. To see what this command is + going to do before risking it, run "../scripts/exim_install -n" (not as + root) from within the build directory. + +. When you are ready to try running Exim, see the section entitled "Testing" + in the chapter called "Building and Installing Exim" in doc/spec.txt, or in + one of the other forms of the documentation. + +. Running the install script does NOT replace /usr/sbin/sendmail or + /usr/lib/sendmail with a link to Exim. That step you must perform by hand + when you are satisfied that Exim is running correctly. + +. Note that the default configuration refers to an alias file called + /etc/aliases. It used to be the case that every Unix had that file, because + it was the Sendmail default. These days, there are systems that don't have + /etc/aliases, so you might need to set it up. Your aliases should at least + include an alias for "postmaster". + +. Consider notifying users of the change of MTA. Exim has different + capabilities, and there are various operational differences, such as stricter + adherence to the RFCs than some MTAs, and differences in the text of + messages produced by various command-line options. + +. The default configuration file will use your host's fully qualified name (as + obtained from the uname() function) as the only local mail domain and as the + domain which is used to qualify unqualified local mail addresses. See the + comments in the default configuration file if you want to change these. + +The operating systems currently supported are: AIX, BSD/OS (aka BSDI), Darwin +(Mac OS X), DGUX, FreeBSD, GNU/Hurd, GNU/Linux, HI-OSF (Hitachi), HP-UX, IRIX, +MIPS RISCOS, NetBSD, OpenBSD, QNX, SCO, SCO SVR4.2 (aka UNIX-SV), Solaris (aka +SunOS5), SunOS4, Tru64-Unix (formerly Digital Unix, formerly DEC-OSF1), Ultrix, +and Unixware. However, code is not available for determining system load +averages on Ultrix. There are also configuration files for compiling Exim in +the Cygwin environment that can be installed on systems running Windows. +However, the documentation supplied with the distribution does not contain any +information about running Exim in the Cygwin environment. + + +******* Modifying the building process ****** + +Instructions for overriding the build-time options for Exim are given in the +manual. You should never have to modify any of the supplied files; it should be +possible to override everything that is necessary by creating suitable files in +the Local directory. This means that you won't need to redo your modifications +for the next release of Exim. If you find you can't avoid changing some other +file, let me know and I'll see if I can find a way of making that unnecessary. + +Briefly, the building process concatenates a number of files in order to +construct its working makefile. If and are the operating +system and architecture types respectively, the files used are: + + OS/Makefile-Default + OS/Makefile- + Local/Makefile + Local/Makefile- + Local/Makefile- + Local/Makefile-- + Local/Makefile- + OS/Makefile-Base + +Of the Local/* files, only Local/Makefile is required to exist; the rest are +optional. Because of the way "make" works, values set in later files override +values set in earlier ones. Thus you can set up general options that are +overridden for specify operating systems and/or architectures if you wish. + + +******* IMPORTANT FOR GNU/LINUX USERS ******* + +Exim 4 won't work with some versions of Linux if you put its spool directory on +an NFS partition. You get an error about "directory sync failed". This is +because of a bug in Linux NFS. A fix has been promised in due course. It is in +any case much better to put Exim's spool directory on local disc. + +If you get an error complaining about the lack of functions such as dbm_open() +when building Exim, the problem is that it hasn't been able to find a DBM +library. See the file doc/dbm.discuss.txt for a discussion about the various +DBM libraries. + +Different versions of Linux come with different DBM libraries, stored in +different places. As well as setting USE_DB=yes in Local/Makefile if Berkeley +DB is in use, it may also be necessary to set a value in DBMLIB to specify the +inclusion of the DBM library, for example: DBMLIB=-ldb or DBMLIB=-lgdbm. + +If you are using RedHat 7.0, which has DB3 as its DBM library, you need to +install the db-devel package before building Exim. This will have a name like +db3-devel-3.1.14-16.i386.rpm (but check which release of DB3 you have). + +The building scripts now distinguish between versions of Linux with the older +libc5 and the more recent ones that use libc6. In the latter case, USE_DB and +-ldb are the default settings, because DB is standard with libc6. + +It appears that with glibc-2.1.x (a minor libc upgrade), they have standardised +on Berkeley DB2 (instead of DB1 in glibc-2.0.x). If you want to get DB1 back, +you need to set + + INCLUDE=-I/usr/include/db1 + DBMLIB=-ldb1 + +in your Local/Makefile. If you omit DBMLIB=-ldb1 Exim will link successfully +using the DB1 compatibility interface to DB2, but it will expect the file +format to be that of DB2, and so will not be able to read existing DB1 files. + + +******* IMPORTANT FOR FREEBSD USERS ******* + +On FreeBSD there is a file called /etc/mail/mailer.conf which selects what to +run for various MTA calls. Instead of changing /usr/sbin/sendmail, you should +edit this file instead, to read something like this: + +sendmail /usr/exim/bin/exim +send-mail /usr/exim/bin/exim +mailq /usr/exim/bin/exim -bp +newaliases /usr/bin/true + +You will most probably need to add the line: + +daily_status_include_submit_mailq="NO" # No separate 'submit' queue + +to /etc/periodic.conf. This stops FreeBSD running the command "mailq -Ac" +(which Exim doesn't understand) to list a separate submit queue (which Exim +doesn't have). + +If you are using FreeBSD prior to 3.0-RELEASE, and you are not using the ports +mechanism to install Exim, then you should install the perl5 package +(/usr/local/bin/perl) and use that instead of perl in the base system, which is +perl4 up until 3.0-RELEASE. If you are using the ports mechanism, this is +handled for you. + +If you are upgrading from version 2.11 of Exim or earlier, and you are using +DBM files, and you did not previously have USE_DB=yes in your Local/Makefile, +then you will either have to put USE_DB=no in your Local/Makefile or (better) +rebuild your DBM data files. The default for FreeBSD has been changed to +USE_DB=yes, since FreeBSD comes with Berkeley DB. However, using the native DB +interface means that the data files no longer have the ".db" extension. + + + +******* IMPORTANT FOR Tru64 (aka Digital Unix aka DEC-OSF1) USERS ******* + +The default compiler may not recognize ANSI C by default. You may have to set + +CC=cc +CFLAGS=-std1 + +in Local/Makefile in order to compile Exim. A user reported another small +problem with this operating system: In the file /usr/include/net/if.h a +semicolon was missing at the end of line 143. + + + +******* IMPORTANT FOR SCO USERS ******* + +The building scripts assume the existence of the "ar" command, which is part of +the Development System. However, it is also possible to use the "gar" command +that is part of the GNU utilities that are distributed with the 5.0.7 release. +If you have "gar" and not "ar" you should include + +AR=gar + +in your Local/Makefile. + + + +******* IMPORTANT FOR Unixware 2.x USERS ******* + +Unixware does not include db/dbm/ndbm with its standard compiler (it is +available with /usr/ucb/cc, but that has bugs of its own). You should install +gcc and Berkeley DB (or another dbm library if you really insist). If you use a +different dbm library you will need to override the default setting of DBMLIB. + +DB 1.85 and 2.x can be found at http://www.sleepycat.com/. They have different +characteristics. See the discussion of dbm libraries in doc/dbm.discuss.txt. DB +needs to be compiled with gcc and you need a 'cc' in your path before the +Unixware CC to compile it. + +Don't bother even starting to install exim on Unixware unless you have +installed gcc and use it for everything. + + +******* IMPORTANT FOR SOLARIS 2.3 (SUNOS 5.3) USERS ******* + +The file /usr/include/sysexits.h does not exist on Solaris 2.3 (and presumably +earlier versions), though it is present in 2.4 and later versions. To compile +Exim on Solaris 2.3 it is necessary to include the line + +CFLAGS=-O -DNO_SYSEXITS -DEX_TEMPFAIL=75 + +in your Local/Makefile. + + +******* IMPORTANT FOR IRIX USERS ******* + +There are problems with some versions of gcc on IRIX, as a result of which all +DNS lookups yield either 0.0.0.0 or 255.255.255.255. Releases of gcc after +2.7.2.3 (which works ok) are affected. Specifically, 2.8.* is affected, as are +the 2.95 series. From release 3.21 of Exim, a workaround for this problem +should automatically be enabled when Exim is compiled on IRIX using gcc. + +As from version 2.03 there is IRIX-specific code in Exim to obtain a list of +all the IP addresses on local interfaces, including alias addresses, because +the standard code gives only non-alias addresses in IRIX. The code came from +SGI, with the comment: + +"On 6.2 you need the libc patch to get the sysctl() stub and the networking +kernel patch to get the support." + +It seems that this code doesn't work on at least some earlier versions of IRIX +(e.g. IRIX 5.3). If you can't compile under IRIX and the problem appears to +relate to sysctl(), try commenting or #ifdef-ing out all the code in the +file OS/os.c-IRIX. + + +******* IMPORTANT FOR HP-UX USERS ******* + +There are two different sets of configuration files for HP-UX. Those ending in +HP-UX-9 are used for HP-UX version 9, and have been tested on HP-UX version +9.05. Those ending in HP-UX are for later releases, and have been tested on +HP-UX version 11.00. If you are using a version of HP-UX between 9.05 and +11.00, you may need to edit the file OS/os.h-HP-UX if you encounter problems +building Exim. + +If you want to use the Sieve facility in Exim, the alias iso-8859-1 should be +added to the alias definition for iso81 in /usr/lib/nls/iconv/config.iconv. You +also need to add a new alias definition: "alias utf8 utf-8". + + +******* IMPORTANT FOR QNX USERS ******* + +1. Exim makes some assumptions about the shell in the makefiles. The "normal" + QNX shell (ksh) will not work. You need to install "bash", which can be + obtained from the QNX freeware on QUICS. Install it to /usr/local/bin/bash + Then you need to change the SHELL definition at the top of the main Makefile + to SHELL=/usr/local/bin/bash. The file OS/Makefile-QNX sets the variable + MAKE_SHELL to /usr/local/bin/bash. If you install bash in a different place, + you will need to set MAKE_SHELL in your Local/Makefile in order to override + this. + +2. For some strange reason make will fail at building "exim_dbmbuild" when + called the first time. However simply calling make a second time will solve + the problem.

Now the length limit should be enforced. +If this affects you, then please rename to use shorter names. + +The default maximum number of recipients of a single email has changed from +"unlimited" (ie: as much as CPU and memory will allow, until something breaks +badly) to 50,000. You can raise or lower this as you see fit, but we strongly +caution against using zero/unlimited. + + +Exim version 4.94 +----------------- + +Some Transports now refuse to use tainted data in constructing their delivery +location; this WILL BREAK configurations which are not updated accordingly. +In particular: any Transport use of $local_part which has been relying upon +check_local_user far away in the Router to make it safe, should be updated to +replace $local_part with $local_part_data. + +Attempting to remove, in router or transport, a header name that ends with +an asterisk (which is a standards-legal name) will now result in all headers +named starting with the string before the asterisk being removed. We recommend +staying away from such names, if they are private ones (and in case of future +enhancements, alao header names that look like REs). + + +Exim version 4.93 +----------------- + +For a detailed list of changes that might affect Exim's operation with +an unchanged configuration, please see the doc/ChangeLog file. + +Build: + + * SUPPORT_DMARC replaces EXPERIMENTAL_DMARC + + * DISABLE_TLS replaces SUPPORT_TLS + + * Bump the version for the local_scan API. + +Runtime: + + * smtp transport option hosts_try_fastopen defaults to "*". + + * DNSSec is requested (not required) for all queries. (This seemes to + ask for trouble if your resolver is a systemd-resolved.) + + * Generic router option retry_use_local_part defaults to "true" under specific + pre-conditions. + + * Introduce a tainting mechanism for values read from untrusted sources. + + * Use longer file names for temporary spool files (this avoids + name conflicts with spool on a shared file system). + + * Use dsn_from main config option (was ignored previously). + + +Exim version 4.92 +----------------- + + * Exim used to manually follow CNAME chains, to a limited depth. In this + day-and-age we expect the resolver to be doing this for us, so the loop + is limited to one retry unless the (new) config option dns_cname_loops + is changed. + +Exim version 4.91 +----------------- + + * DANE and SPF have been promoted from Experimental to Supported status, thus + the options to enable them in Local/Makefile have been renamed. + See current src/EDITME for full details, including changes in dependencies, + but loosely: replace EXPERIMENTAL_SPF with SUPPORT_SPF and replace + EXPERIMENTAL_DANE with SUPPORT_DANE. + + * Ancient ClamAV stream support, long deprecated by ClamAV, has been removed; + if you were building with WITH_OLD_CLAMAV_STREAM enabled then your problems + have marginally increased. + + * A number of logging changes; if relying upon the previous DKIM additional + log-line, explicit log_selector configuration is needed to keep it. + + * Other incompatible changes in EXPERIMENTAL_* features, read NewStuff and + ChangeLog carefully if relying upon an experimental feature such as DMARC. + Note that this includes changes to SPF as it was promoted into Supported. + + +Exim version 4.89 +----------------- + + * SMTP CHUNKING in Exim 4.88 did not ensure that received mails had a final + newline; attempts to deliver such messages onwards to non-chunking hosts + would probably hang, as Exim does not insert the newline before a ".". + In 4.89, the newline is added upon receipt. For already-received messages + in your queue, try util/chunking_fixqueue_finalnewlines.pl + to walk the queue, fixing any affected messages. Note that because a + delivery attempt will be hanging, attempts to lock the messages for fixing + them will stall; stopping all queue-runners temporarily is recommended. + + * OpenSSL: oldest supported release series is now 1.0.2, which is the oldest + supported by the OpenSSL project. If you can build Exim with an older + release series, congratulations. If you can't, then upgrade. + The file doc/openssl.txt contains instructions for installing a current + OpenSSL outside the system library paths and building Exim to use it. + + * FreeBSD: we now always use the system iconv in libc, as all versions of + FreeBSD supported by the FreeBSD project provide this functionality. + + +Exim version 4.88 +----------------- + + * The "demime" ACL condition, deprecated for the past 10 years, has + now been removed. + + * Old GnuTLS configuration options "gnutls_require_kx", "gnutls_require_mac", + and "gnutls_require_protocols" have now been removed. (Inoperative from + 4.80, per below; logging warnings since 4.83, again per below). + + +Exim version 4.83 +----------------- + + * SPF condition results renamed "permerror" and "temperror". The old + names are still accepted for back-compatibility, for this release. + + * TLS details are now logged on rejects, subject to log selectors. + + * Items in headers_remove lists must now have any embedded list-separators + doubled. + + * Attempted use of the deprecated options "gnutls_require_kx" et. al. + now result in logged warning. + + +Exim version 4.82 +----------------- + + * New option gnutls_allow_auto_pkcs11 defaults false; if you have GnuTLS 2.12.0 + or later and do want PKCS11 modules to be autoloaded, then set this option. + + * A per-transport wait- database is no longer updated if the transport + sets "connection_max_messages" to 1, as it can not be used and causes + unnecessary serialisation and load. External tools tracking the state of + Exim by the hints databases may need modification to take this into account. + + * The av_scanner option can now accept multiple clamd TCP targets, all other + setting limitations remain. + + +Exim version 4.80 +----------------- + + * BEWARE backwards-incompatible changes in SSL libraries, thus the version + bump. See points below for details. + Also an LDAP data returned format change. + + * The value of $tls_peerdn is now print-escaped when written to the spool file + in a -tls_peerdn line, and unescaped when read back in. We received reports + of values with embedded newlines, which caused spool file corruption. + + If you have a corrupt spool file and you wish to recover the contents after + upgrading, then lock the message, replace the new-lines that should be part + of the -tls_peerdn line with the two-character sequence \n and then unlock + the message. No tool has been provided as we believe this is a rare + occurrence. + + * For OpenSSL, SSLv2 is now disabled by default. (GnuTLS does not support + SSLv2). RFC 6176 prohibits SSLv2 and some informal surveys suggest no + actual usage. You can re-enable with the "openssl_options" Exim option, + in the main configuration section. Note that supporting SSLv2 exposes + you to ciphersuite downgrade attacks. + + * With OpenSSL 1.0.1+, Exim now supports TLS 1.1 and TLS 1.2. If built + against 1.0.1a then you will get a warning message and the + "openssl_options" value will not parse "no_tlsv1_1": the value changes + incompatibly between 1.0.1a and 1.0.1b, because the value chosen for 1.0.1a + is infelicitous. We advise avoiding 1.0.1a. + + "openssl_options" gains "no_tlsv1_1", "no_tlsv1_2" and "no_compression". + + COMPATIBILITY WARNING: The default value of "openssl_options" is no longer + "+dont_insert_empty_fragments". We default to "+no_sslv2". + That old default was grandfathered in from before openssl_options became a + configuration option. + Empty fragments are inserted by default through TLS1.0, to partially defend + against certain attacks; TLS1.1+ change the protocol so that this is not + needed. The DIEF SSL option was required for some old releases of mail + clients which did not gracefully handle the empty fragments, and was + initially set in Exim release 4.31 (see ChangeLog, item 37). + + If you still have affected mail-clients, and you see SSL protocol failures + with this release of Exim, set: + openssl_options = +dont_insert_empty_fragments + in the main section of your Exim configuration file. You're trading off + security for compatibility. Exim is now defaulting to higher security and + rewarding more modern clients. + + If the option tls_dhparams is set and the parameters loaded from the file + have a bit-count greater than the new option tls_dh_max_bits, then the file + will now be ignored. If this affects you, raise the tls_dh_max_bits limit. + We suspect that most folks are using dated defaults and will not be affected. + + * Ldap lookups returning multi-valued attributes now separate the attributes + with only a comma, not a comma-space sequence. Also, an actual comma within + a returned attribute is doubled. This makes it possible to parse the + attribute as a comma-separated list. Note the distinction from multiple + attributes being returned, where each one is a name=value pair. + + If you are currently splitting the results from LDAP upon a comma, then you + should check carefully to see if adjustments are needed. + + This change lets cautious folks distinguish "comma used as separator for + joining values" from "comma inside the data". + + * accept_8bitmime now defaults on, which is not RFC compliant but is better + suited to today's Internet. See http://cr.yp.to/smtp/8bitmime.html for a + sane rationale. Those who wish to be strictly RFC compliant, or know that + they need to talk to servers that are not 8-bit-clean, now need to take + explicit configuration action to default this option off. This is not a + new option, you can safely force it off before upgrading, to decouple + configuration changes from the binary upgrade while remaining RFC compliant. + + * The GnuTLS support has been mostly rewritten, to use APIs which don't cause + deprecation warnings in GnuTLS 2.12.x. As part of this, these three options + are no longer supported: + + gnutls_require_kx + gnutls_require_mac + gnutls_require_protocols + + Their functionality is entirely subsumed into tls_require_ciphers. In turn, + tls_require_ciphers is no longer an Exim list and is not parsed by Exim, but + is instead given to gnutls_priority_init(3), which expects a priority string; + this behaviour is much closer to the OpenSSL behaviour. See: + + http://www.gnutls.org/manual/html_node/Priority-Strings.html + + for fuller documentation of the strings parsed. The three gnutls_require_* + options are still parsed by Exim and, for this release, silently ignored. + A future release will add warnings, before a later still release removes + parsing entirely and the presence of the options will be a configuration + error. + + Note that by default, GnuTLS will not accept RSA-MD5 signatures in chains. + A tls_require_ciphers value of NORMAL:%VERIFY_ALLOW_SIGN_RSA_MD5 may + re-enable support, but this is not supported by the Exim maintainers. + Our test suite no longer includes MD5-based certificates. + + This rewrite means that Exim will continue to build against GnuTLS in the + future, brings Exim closer to other GnuTLS applications and lets us add + support for SNI and other features more readily. We regret that it wasn't + feasible to retain the three dropped options. + + * If built with TLS support, then Exim will now validate the value of + the main section tls_require_ciphers option at start-up. Before, this + would cause a STARTTLS 4xx failure, now it causes a failure to start. + Running with a broken configuration which causes failures that may only + be left in the logs has been traded off for something more visible. This + change makes an existing problem more prominent, but we do not believe + anyone would deliberately be running with an invalid tls_require_ciphers + option. + + This also means that library linkage issues caused by conflicts of some + kind might take out the main daemon, not just the delivery or receiving + process. Conceivably some folks might prefer to continue delivering + mail plaintext when their binary is broken in this way, if there is a + server that is a candidate to receive such mails that does not advertise + STARTTLS. Note that Exim is typically a setuid root binary and given + broken linkage problems that cause segfaults, we feel it is safer to + fail completely. (The check is not done as root, to ensure that problems + here are not made worse by the check). + + * The "tls_dhparam" option has been updated, so that it can now specify a + path or an identifier for a standard DH prime from one of a few RFCs. + The default for OpenSSL is no longer to not use DH but instead to use + one of these standard primes. The default for GnuTLS is no longer to use + a file in the spool directory, but to use that same standard prime. + The option is now used by GnuTLS too. If it points to a path, then + GnuTLS will use that path, instead of a file in the spool directory; + GnuTLS will attempt to create it if it does not exist. + + To preserve the previous behaviour of generating files in the spool + directory, set "tls_dhparam = historic". Since prior releases of Exim + ignored tls_dhparam when using GnuTLS, this can safely be done before + the upgrade. + + + +Exim version 4.77 +----------------- + + * GnuTLS will now attempt to use TLS 1.2 and TLS 1.1 before TLS 1.0 and SSL3, + if supported by your GnuTLS library. Use the existing + "gnutls_require_protocols" option to downgrade this if that will be a + problem. Prior to this release, supported values were "TLS1" and "SSL3", + so you should be able to update configuration prior to update. + + [nb: gnutls_require_protocols removed in Exim 4.80, instead use + tls_require_ciphers to provide a priority string; see notes above] + + * The match_{string1}{string2} expansion conditions no longer subject + string2 to string expansion, unless Exim was built with the new + "EXPAND_LISTMATCH_RHS" option. Too many people have inadvertently created + insecure configurations that way. If you need the functionality and turn on + that build option, please let the developers know, and know why, so we can + try to provide a safer mechanism for you. + + The match{}{} expansion condition (for regular expressions) is NOT affected. + For match_{s1}{s2}, all list functionality is unchanged. The only + change is that a '$' appearing in s2 will not trigger expansion, but instead + will be treated as a literal $ sign; the effect is very similar to having + wrapped s2 with \N...\N. If s2 contains a named list and the list definition + uses $expansions then those _will_ be processed as normal. It is only the + point at which s2 is read where expansion is inhibited. + + If you are trying to test if two email addresses are equal, use eqi{s1}{s2}. + If you are testing if the address in s1 occurs in the list of items given + in s2, either use the new inlisti{s1}{s2} condition (added in 4.77) or use + the pre-existing forany{s2}{eqi{$item}{s1}} condition. + + +Exim version 4.74 +----------------- + + * The integrated support for dynamically loadable lookup modules has an ABI + change from the modules supported by some OS vendors through an unofficial + patch. Don't try to mix & match. + + * Some parts of the build system are now beginning to assume that the host + environment is POSIX. If you're building on a system where POSIX tools are + not the default, you might have an easier time if you switch to the POSIX + tools. Feel free to report non-POSIX issues as a request for a feature + enhancement, but if the POSIX variants are available then the fix will + probably just involve some coercion. See the README instructions for + building on such hosts. + + +Exim version 4.73 +----------------- + + * The Exim run-time user can no longer be root; this was always + strongly discouraged, but is now prohibited both at build and + run-time. If you need Exim to run routinely as root, you'll need to + patch the source and accept the risk. Here be dragons. + + * Exim will no longer accept a configuration file owned by the Exim + run-time user, unless that account is explicitly the value in + CONFIGURE_OWNER, which we discourage. Exim now checks to ensure that + files are not writeable by other accounts. + + * The ALT_CONFIG_ROOT_ONLY build option is no longer optional and is forced + on; the Exim user can, by default, no longer use -C/-D and retain privilege. + Two new build options mitigate this. + + * TRUSTED_CONFIG_LIST defines a file containing a whitelist of config + files that are trusted to be selected by the Exim user; one per line. + This is the recommended approach going forward. + + * WHITELIST_D_MACROS defines a colon-separated list of macro names which + the Exim run-time user may safely pass without dropping privileges. + Because changes to this involve a recompile, this is not the recommended + approach but may ease transition. The values of the macros, when + overridden, are constrained to match this regex: ^[A-Za-z0-9_/.-]*$ + + * The system_filter_user option now defaults to the Exim run-time user, + rather than root. You can still set it explicitly to root and this + can be done with prior versions too, letting you roll versions + without needing to change this configuration option. + + * ClamAV must be at least version 0.95 unless WITH_OLD_CLAMAV_STREAM is + defined at build time. + + +Exim version 4.70 +----------------- + +1. Experimental Yahoo! Domainkeys support has been dropped in this release. +It has been superseded by a native implementation of its successor DKIM. + +2. Up to version 4.69, Exim came with an embedded version of the PCRE library. +As of 4.70, this is no longer the case. To compile Exim, you will need PCRE +installed. Most OS distributions have ready-made library and development +packages. + + +Exim version 4.68 +----------------- + +1. The internal implementation of the database keys that are used for ACL +ratelimiting has been tidied up. This means that an update to 4.68 might cause +Exim to "forget" previous rates that it had calculated, and reset them to zero. + + +Exim version 4.64 +----------------- + +1. Callouts were setting the name used for EHLO/HELO from $smtp_active_ +hostname. This is wrong, because it relates to the incoming message (and +probably the interface on which it is arriving) and not to the outgoing +callout (which could be using a different interface). This has been +changed to use the value of the helo_data option from the smtp transport +instead - this is what is used when a message is actually being sent. If +there is no remote transport (possible with a router that sets up host +addresses), $smtp_active_hostname is used. This change is mentioned here in +case somebody is relying on the use of $smtp_active_hostname. + +2. A bug has been fixed that might just possibly be something that is relied on +in some configurations. In expansion items such as ${if >{xxx}{yyy}...} an +empty string (that is {}) was being interpreted as if it was {0} and therefore +treated as the number zero. From release 4.64, such strings cause an error +because a decimal number, possibly followed by K or M, is required (as has +always been documented). + +3. There has been a change to the GnuTLS support (ChangeLog/PH/20) to improve +Exim's performance. Unfortunately, this has the side effect of being slightly +non-upwards compatible for versions 4.50 and earlier. If you are upgrading from +one of these earlier versions and you use GnuTLS, you must remove the file +called gnutls-params in Exim's spool directory. If you don't do this, you will +see this error: + + TLS error on connection from ... (DH params import): Base64 decoding error. + +Removing the file causes Exim to recompute the relevant encryption parameters +and cache them in the new format that was introduced for release 4.51 (May +2005). If you are upgrading from release 4.51 or later, there should be no +problem. + + +Exim version 4.63 +----------------- + +When an SMTP error message is specified in a "message" modifier in an ACL, or +in a :fail: or :defer: message in a redirect router, Exim now checks the start +of the message for an SMTP error code. This consists of three digits followed +by a space, optionally followed by an extended code of the form n.n.n, also +followed by a space. If this is the case and the very first digit is the same +as the default error code, the code from the message is used instead. If the +very first digit is incorrect, a panic error is logged, and the default code is +used. This is an incompatible change, but it is not expected to affect many (if +any) configurations. It is possible to suppress the use of the supplied code in +a redirect router by setting the smtp_error_code option false. In this case, +any SMTP code is quietly ignored. + + +Exim version 4.61 +----------------- + +1. The default number of ACL variables of each type has been increased to 20, +and it's possible to compile Exim with more. You can safely upgrade to this +release if you already have messages on the queue with saved ACL variable +values. However, if you downgrade from this release with messages on the queue, +any saved ACL values they may have will be lost. + +2. The default value for rfc1413_query_timeout has been changed from 30s to 5s. + + +Exim version 4.54 +----------------- + +There was a problem with 4.52/TF/02 in that a "name=" option on control= +submission terminated at the next slash, thereby not allowing for slashes in +the name. This has been changed so that "name=" takes the rest of the string as +its data. It must therefore be the last option. + + +Version 4.53 +------------ + +If you are using the experimental Domain Keys support, you must upgrade to +at least libdomainkeys 0.67 in order to run this release of Exim. + + +Version 4.51 +------------ + +1. The format in which GnuTLS parameters are cached (in the file gnutls-params +in the spool directory) has been changed. The new format can also be generated +externally, so it is now possible to update the values from outside Exim. This +has been implemented in an upwards, BUT NOT downwards, compatible manner. +Upgrading should be seamless: when Exim finds that it cannot understand an +existing cache file, it generates new parameters and writes them to the cache +in the new format. If, however, you downgrade from 4.51 to a previous release, +you MUST delete the gnutls-params file in the spool directory, because the +older Exim will not recognize the new format. + +2. When doing a callout as part of verifying an address, Exim was not paying +attention to any local part prefix or suffix that was matched by the router +that accepted the address. It now behaves in the same way as it does for +delivery: the affixes are removed from the local part unless +rcpt_include_affixes is set on the transport. If you have a configuration that +uses prefixes or suffixes on addresses that could be used for callouts, and you +want the affixes to be retained, you must make sure that rcpt_include_affixes +is set on the transport. + +3. Bounce and delay warning messages no longer contain details of delivery +errors, except for explicit messages (e.g. generated by :fail:) and SMTP +responses from remote hosts. + + +Version 4.50 +------------ + +The exicyclog script has been updated to use three-digit numbers in rotated log +files if the maximum number to keep is greater than 99. If you are already +keeping more than 99, there will be an incompatible change when you upgrade. +You will probably want to rename your old log files to the new form before +running the new exicyclog. + + +Version 4.42 +------------ + +RFC 3848 specifies standard names for the "with" phrase in Received: header +lines when AUTH and/or TLS are in use. This is the "received protocol" +field. Exim used to use "asmtp" for authenticated SMTP, without any +indication (in the protocol name) for TLS use. Now it follows the RFC and +uses "esmtpa" if the connection is authenticated, "esmtps" if it is +encrypted, and "esmtpsa" if it is both encrypted and authenticated. These names +appear in log lines as well as in Received: header lines. + + +Version 4.34 +------------ + +Change 4.31/2 gave problems to data ACLs and local_scan() functions that +expected to see a Received: header. I have changed to yet another scheme. The +Received: header is now generated after the body is received, but before the +ACL or local_scan() is called. After they have run, the timestamp in the +Received: header is updated. + +Thus, change (a) of 4.31/2 has been reversed, but change (b) is still true, +which is lucky, since I decided it was a bug fix. + + +Version 4.33 +------------ + +If an expansion in a condition on a "warn" statement fails because a lookup +defers, the "warn" statement is abandoned, and the next ACL statement is +processed. Previously this caused the whole ACL to be aborted. + + +Version 4.32 +------------ + +Change 4.31/2 has been reversed, as it proved contentious. Recipient callout +verification now uses <> in the MAIL command by default, as it did before. A +new callout option, "use_sender", has been added to request the other +behaviour. + + +Version 4.31 +------------ + +1. If you compile Exim to use GnuTLS, it now requires the use of release 1.0.0 + or greater. The interface to the obsolete 0.8.x releases is no longer + supported. There is one externally visible change: the format for the + display of Distinguished Names now uses commas as a separator rather than a + slash. This is to comply with RFC 2253. + +2. When a message is received, the Received: header line is now generated when + reception is complete, instead of at the start of reception. For messages + that take a long time to come in, this changes the meaning of the timestamp. + There are several side-effects of this change: + + (a) If a message is rejected by a DATA or non-SMTP ACL, or by local_scan(), + the logged header lines no longer include the local Received: line, + because it has not yet been created. If the message is a non-SMTP one, + and the error is processed by sending a message to the sender, the copy + of the original message that is returned does not have an added + Received: line. + + (b) When a filter file is tested using -bf, no additional Received: header + is added to the test message. After some thought, I decided that this + is a bug fix. + + The contents of $received_for are not affected by this change. This + variable still contains the single recipient of a message, copied after + addresses have been rewritten, but before local_scan() is run. + +2. Recipient callout verification, like sender verification, was using <> in + the MAIL FROM command. This isn't really the right thing, since the actual + sender may affect whether the remote host accepts the recipient or not. I + have changed it to use the actual sender in the callout; this means that + the cache record is now keyed on a recipient/sender pair, not just the + recipient address. There doesn't seem to be a real danger of callout loops, + since a callout by the remote host to check the sender would use <>. + + +Version 4.30 +------------ + +1. I have abolished timeout_DNS as an error that can be detected in retry + rules, because it has never worked. Despite the fact that it has been + documented since at least release 1.62, there was no code to support it. + If you have used it in your retry rules, you will now get a warning message + to the log and panic log. It is now treated as plain "timeout". + +2. After discussion on the mailing list, Exim no longer adds From:, Date:, or + Message-Id: header lines to messages that do not originate locally, that is, + messages that have an associated sending host address. + +3. When looking up a host name from an IP address, Exim now tries the DNS + first, and only if that fails does it use gethostbyaddr() (or equivalent). + This change was made because on some OS, not all the names are given for + addresses with multiple PTR records via the gethostbyaddr() interface. The + order of lookup can be changed by setting host_lookup_order. + + +Version 4.23 +------------ + +1. The new FIXED_NEVER_USERS build-time option creates a list of "never users" + that cannot be overridden. The default in the distributed EDITME is "root". + If for some reason you were (against advice) running deliveries as root, you + will have to ensure that FIXED_NEVER_USERS is not set in your + Local/Makefile. + +2. The ${quote: operator now quotes an empty string, which it did not before. + +3. Version 4.23 saves the contents of the ACL variables with the message, so + that they can be used later. If one of these variables contains a newline, + there will be a newline character in the spool that will not be interpreted + correctly by a previous version of Exim. (Exim ignores keyed spool file + items that it doesn't understand - precisely for this kind of problem - but + it expects them all to be on one line.) + + So the bottom line is: if you have newlines in your ACL variables, you + cannot retreat from 4.23. + + +Version 4.21 +------------ + +1. The idea of the "warn" ACL verb is that it adds a header or writes to the + log only when "message" or "log_message" are set. However, if one of the + conditions was an address verification, or a call to a nested ACL, the + messages generated by the underlying test were being passed through. This + no longer happens. The underlying message is available in $acl_verify_ + message for both "message" and "log_message" expansions, so it can be + passed through if needed. + +2. The way that the $h_ (and $header_) expansions work has been changed by the + addition of RFC 2047 decoding. See the main documentation (the NewStuff file + until release 4.30, then the manual) for full details. Briefly, there are + now three forms: + + $rh_xxx: and $rheader_xxx: give the original content of the header + line(s), with no processing at all. + + $bh_xxx: and $bheader_xxx: remove leading and trailing white space, and + then decode base64 or quoted-printable "words" within the header text, + but do not do charset translation. + + $h_xxx: and $header_xxx: attempt to translate the $bh_ string to a + standard character set. + + If you have previously been using $h_ expansions to access the raw + characters, you should change to $rh_ instead. + +3. When Exim creates an RFC 2047 encoded word in a header line, it labels it + with the default character set from the headers_charset option instead of + always using iso-8859-1. + +4. If TMPDIR is defined in Local/Makefile (default in src/EDITME is + TMPDIR="/tmp"), Exim checks for the presence of an environment variable + called TMPDIR, and if it finds it is different, it changes its value. + +5. Following a discussion on the list, the rules by which Exim recognises line + endings on incoming messages have been changed. The -dropcr and drop_cr + options are now no-ops, retained only for backwards compatibility. The + following line terminators are recognized: LF CRLF CR. However, special + processing applies to CR: + + (i) The sequence CR . CR does *not* terminate an incoming SMTP message, + nor a local message in the state where . is a terminator. + + (ii) If a bare CR is encountered in a header line, an extra space is added + after the line terminator so as not to end the header. The reasoning + behind this is that bare CRs in header lines are most likely either + to be mistakes, or people trying to play silly games. + +6. The code for using daemon_smtp_port, local_interfaces, and the -oX options + has been reorganized. It is supposed to be backwards compatible, but it is + mentioned here just in case I've screwed up. + + + +Version 4.20 +------------ + +1. I have tidied and re-organized the code that uses alarm() for imposing time + limits on various things. It shouldn't affect anything, but if you notice + processes getting stuck, it may be that I've broken something. + +2. The "arguments" log selector now also logs the current working directory + when Exim is called. + +3. An incompatible change has been made to the appendfile transport. This + affects the case when it is used for file deliveries that are set up by + .forward and filter files. Previously, any settings of the "file" or + "directory" options were ignored. It is hoped that, like the address_file + transport in the default configuration, these options were never in fact set + on such transports, because they were of no use. + + Now, if either of these options is set, it is used. The path that is passed + by the router is in $address_file (this is not new), so it can be used as + part of a longer path, or modified in any other way that expansion permits. + + If neither "file" nor "directory" is set, the behaviour is unchanged. + +4. Related to the above: in a filter, if a "save" command specifies a non- + absolute path, the value of $home/ is pre-pended. This no longer happens if + $home is unset or is set to an empty string. + +5. Multiple file deliveries from a filter or .forward file can never be + batched; the value of batch_max on the transport is ignored for file + deliveries. I'm assuming that nobody ever actually set batch_max on the + address_file transport - it would have had odd effects previously. + +6. DESTDIR is the more common variable that ROOT for use when installing + software under a different root filing system. The Exim install script now + recognizes DESTDIR first; if it is not set, ROOT is used. + +7. If DESTDIR is set when installing Exim, it no longer prepends its value to + the path of the system aliases file that appears in the default + configuration (when a default configuration is installed). If an aliases + file is actually created, its name *does* use the prefix. + + +Version 4.14 +------------ + +1. The default for the maximum number of unknown SMTP commands that Exim will +accept before dropping a connection has been reduced from 5 to 3. However, you +can now change the value by setting smtp_max_unknown_commands. + +2. The ${quote: operator has been changed so that it turns newline and carriage +return characters into \n and \r, respectively. + +3. The file names used for maildir messages now include the microsecond time +fraction as well as the time in seconds, to cope with systems where the process +id can be re-used within the same second. The format is now + +
