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

771 3. BUILD TIME OPTIONS FOR EXIM
772 ------------------------------
774 The table below contains a "mostly" complete list of options that can be
775 set in Local/Makefile when building Exim. The only items not included are
776 those whose names can be trivially derived from rules stated below.
778 More information about individual options can be found in src/EDITME and
781 The 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;
795 Those marked with * are specialized and are unlikely to be required in most
796 installations. Those that are marked with ** are commonly set in OS-specific
797 Makefiles. If you use any of these in your Local/Makefile, you may need to
798 reproduce some of the OS-specific settings. For example, in the Makefile for
799 Solaris (which is actually called OS/Makefile-SunOS5), there is
801 LIBS=-lsocket -lnsl -lkstat
803 If you use LIBS to add extra libraries, you must also include the OS ones in
804 your setting. It is better, in this particular case, to use EXTRALIBS, which is
805 empty by default, and is provided for just this reason. Of course, if you do
806 actually want to modify a setting from the OS-specific file, there is nothing
807 to stop you overriding it in your Local/Makefile.
809 When building Exim with dynamically loaded lookup support, for "LOOKUP_FOO",
810 you can define "LOOKUP_FOO_INCLUDE" and "LOOKUP_FOO_LIBS", for includes and
811 libraries specific only to that module. These rules are only used where the
812 relevant lookup is a module. These options are not explicitly listed below.
814 Variables with names endined `_PC' are used for pkg-config integration; setting
815 the value to the name of a pkg-config package will cause Exim's build system to
816 query the --cflags and --libs for the given name, when building anything
817 dependent upon the component associated with the `_PC' variable. For lookups,
818 if the lookup is dynamically loaded, then this *replaces* the use of the
819 corresponding _INCLUDE and _LIBS options, which will be ignored. If the lookup
820 is statically loaded into Exim, the results will be inserted into the
821 "LOOKUP_INCLUDE" and "LOOKUP_LIBS" options. For authenticator, the results
822 will be inserted into the "CFLAGS" and "AUTH_LIBS" options. These options are
823 only listed below for the TLS implementation cases.
