0bd1a913 4This file contains complete lists of four kinds of Exim option:
6 1. Those that can appear in the run time configuration file;
7 2. Those that can be used on the command line;
8 3. Those that can appear in the build time configuration (Local/Makefile);
9 4. Those that can appear in the build time configuration for the Exim monitor
10 (Local/eximon.conf).
22380b86 12This file was last updated for Exim release 4.72.
18As Exim has developed, new options have been added at each major release. For
19the most part, backwards compatibility has been maintained, and obsolete
20options continue to be recognized. However, incompatible changes took place at
21releases 3.00, and 4.00. In both cases, several groups of options were
22amalgamated into new, extended options, and obsolete options were removed.
24The table below contains a complete list of all Exim's current options, along
25with their types, default values, and where they can be used. String options
26that are expanded before use are marked with *. Host lists, domain lists, and
27address lists are always expanded. In some cases the defaults are not fixed
28values, or not short enough to fit in the table. These are indicated by +. Some
29other default values are determined when the Exim binary is compiled; these are
30indicated by ++.
32For options that are specific to a particular driver, the fourth column
33contains the driver name, for example, appendfile. Otherwise, it contains
35 . `main' for options that appear in the main section of Exim's configuration
36 file;
38 . `authenticators' for generic options that apply to any authenticator;
40 . `routers' for generic options that apply to any router;
42 . `transports' for generic options that apply to any transport.
44The fifth column contains the version of Exim in which the option was added, or
45substantially changed. Where no number is given, the option has been in Exim
46since the very early releases. The routers were completely reorganised for
47release 4.00, and so no router options are shown as earlier than 4.00, though
48in fact some of them were inherited from earlier versions.

774The table below contains a "mostly" complete list of options that can be
775set in Local/Makefile when building Exim. The only items not included are
776those whose names can be trivially derived from rules stated below.
778More information about individual options can be found in src/EDITME and
781The second column below gives the type of option:
783 . `system' means the option is concerned with the operating system;
785 . `driver' means the option selects a driver to be included in the binary;
787 . `lookup' means the option selects a lookuptype to be included in the binary;
789 . `mandatory' means the option is required to be supplied;
791 . `recommended' means the option is recommended to be supplied;
793 . `optional' means what it says;
795Those marked with * are specialized and are unlikely to be required in most
796installations. Those that are marked with ** are commonly set in OS-specific
797Makefiles. If you use any of these in your Local/Makefile, you may need to
798reproduce some of the OS-specific settings. For example, in the Makefile for
799Solaris (which is actually called OS/Makefile-SunOS5), there is
801 LIBS=-lsocket -lnsl -lkstat
803If you use LIBS to add extra libraries, you must also include the OS ones in
804your setting. It is better, in this particular case, to use EXTRALIBS, which is
805empty by default, and is provided for just this reason. Of course, if you do
806actually want to modify a setting from the OS-specific file, there is nothing
807to stop you overriding it in your Local/Makefile.
809When building Exim with dynamically loaded lookup support, for "LOOKUP_FOO",
810you can define "LOOKUP_FOO_INCLUDE" and "LOOKUP_FOO_LIBS", for includes and
811libraries specific only to that module. These rules are only used where the
812relevant lookup is a module. These options are not explicitly listed below.
814Variables with names endined `_PC' are used for pkg-config integration; setting
815the value to the name of a pkg-config package will cause Exim's build system to
816query the --cflags and --libs for the given name, when building anything
817dependent upon the component associated with the `_PC' variable. For lookups,
818if the lookup is dynamically loaded, then this *replaces* the use of the
819corresponding _INCLUDE and _LIBS options, which will be ignored. If the lookup
820is statically loaded into Exim, the results will be inserted into the
821"LOOKUP_INCLUDE" and "LOOKUP_LIBS" options. For authenticator, the results
822will be inserted into the "CFLAGS" and "AUTH_LIBS" options. These options are
823only listed below for the TLS implementation cases.
