3 LISTS OF EXIM OPTIONS
4 ---------------------
5
6 This file contains complete lists of four kinds of Exim option:
7
8   1. Those that can appear in the run time configuration file;
9   2. Those that can be used on the command line;
10   3. Those that can appear in the build time configuration (Local/Makefile);
11   4. Those that can appear in the build time configuration for the Exim monitor
12      (Local/eximon.conf).
13
14 This file was last updated for Exim release 4.51.

17 1. RUN TIME OPTIONS
18 -------------------
19
20 As Exim has developed, new options have been added at each major release. For
21 the most part, backwards compatibility has been maintained, and obsolete
22 options continue to be recognized. However, incompatible changes took place at
23 releases 3.00, and 4.00. In both cases, several groups of options were
24 amalgamated into new, extended options, and obsolete options were removed.
25
26 The table below contains a complete list of all Exim's current options, along
27 with their types, default values, and where they can be used. String options
28 that are expanded before use are marked with *. Host lists, domain lists, and
29 address lists are always expanded. In some cases the defaults are not fixed
30 values, or not short enough to fit in the table. These are indicated by +. Some
31 other default values are determined when the Exim binary is compiled; these are
32 indicated by ++.
33
34 For options that are specific to a particular driver, the fourth column
35 contains the driver name, for example, appendfile. Otherwise, it contains
36
37  . `main' for options that appear in the main section of Exim's configuration
38     file;
39
40  . `authenticators' for generic options that apply to any authenticator;
41
42  . `routers' for generic options that apply to any router;
43
44  . `transports' for generic options that apply to any transport.
45
46 The fifth column contains the version of Exim in which the option was added, or
47 substantially changed. Where no number is given, the option has been in Exim
48 since the very early releases. The routers were completely reorganised for
49 release 4.00, and so no router options are shown as earlier than 4.00, though
50 in fact some of them were inherited from earlier versions.

696 3. BUILD TIME OPTIONS FOR EXIM
697 ------------------------------
698
699 The table below contains a complete list of options that can be set in
700 Local/Makefile when building Exim. More information about individual options
701 can be found in src/EDITME and OS/Makefile-Default.
702
703 The second column below gives the type of option:
704
705  . `system' means the option is concerned with the operating system;
706
707  . `driver' means the option selects a driver to be included in the binary;
708
709  . `lookup' means the option selects a lookuptype to be included in the binary;
710
711  . `mandatory' means the option is required to be supplied;
712
713  . `recommended' means the option is recommended to be supplied;
714
715  . `optional' means what it says;
716
717 Those marked with * are specialized and are unlikely to be required in most
718 installations. Those that are marked with ** are commonly set in OS-specific
719 Makefiles. If you use any of these in your Local/Makefile, you may need to
720 reproduce some of the OS-specific settings. For example, in the Makefile for
721 Solaris (which is actually called OS/Makefile-SunOS5), there is
722
723   LIBS=-lsocket -lnsl -lkstat
724
725 If you use LIBS to add extra libraries, you must also include the OS ones in
726 your setting. It is better, in this particular case, to use EXTRALIBS, which is
727 empty by default, and is provided for just this reason. Of course, if you do
728 actually want to modify a setting from the OS-specific file, there is nothing
729 to stop you overriding it in your Local/Makefile.
