6 This file contains complete lists of four kinds of Exim option:
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
14 This file was last updated for Exim release 4.72.
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.
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
34 For options that are specific to a particular driver, the fourth column
35 contains the driver name, for example, appendfile. Otherwise, it contains
37 . `main' for options that appear in the main section of Exim's configuration
40 . `authenticators' for generic options that apply to any authenticator;
42 . `routers' for generic options that apply to any router;
44 . `transports' for generic options that apply to any transport.
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.

735 3. BUILD TIME OPTIONS FOR EXIM
736 ------------------------------
738 The table below contains a complete list of options that can be set in
739 Local/Makefile when building Exim. More information about individual options
740 can be found in src/EDITME and OS/Makefile-Default.
742 The second column below gives the type of option:
744 . `system' means the option is concerned with the operating system;
746 . `driver' means the option selects a driver to be included in the binary;
748 . `lookup' means the option selects a lookuptype to be included in the binary;
750 . `mandatory' means the option is required to be supplied;
752 . `recommended' means the option is recommended to be supplied;
754 . `optional' means what it says;
756 Those marked with * are specialized and are unlikely to be required in most
757 installations. Those that are marked with ** are commonly set in OS-specific
758 Makefiles. If you use any of these in your Local/Makefile, you may need to
759 reproduce some of the OS-specific settings. For example, in the Makefile for
760 Solaris (which is actually called OS/Makefile-SunOS5), there is
762 LIBS=-lsocket -lnsl -lkstat
764 If you use LIBS to add extra libraries, you must also include the OS ones in
765 your setting. It is better, in this particular case, to use EXTRALIBS, which is
766 empty by default, and is provided for just this reason. Of course, if you do
767 actually want to modify a setting from the OS-specific file, there is nothing
768 to stop you overriding it in your Local/Makefile.

933 4. BUILD TIME OPTIONS FOR EXIMON
934 --------------------------------
936 The table below contains a complete list of options that can be set in
937 Local/eximon.conf when building the Exim monitor. Where the default is shown as
938 ** it means that the text string is too long to fit in the table and is instead
939 given below. A blank default means that there is no default value.

967 The default for LOG_FONT is
969 LOG_FONT=-misc-fixed-medium-r-normal-*-14-140-*-*-*-*-iso8859-1
971 and the default for LOG_STRIPCHARTS is
973 LOG_STRIPCHARTS='/ <= /in/
975 / => .+ R=local/local/
976 / => .+ T=[^ ]*smtp/smtp/'
978 That is, there are four stripcharts, named in, out, local, and smtp. The first
979 counts message arrivals, the second counts all deliveries, the third counts
980 deliveries where the router's name starts with "local", and the fourth counts
981 deliveries where the transport name contains "smtp".
