1LISTS OF EXIM OPTIONS
2---------------------
3
4This file contains complete lists of four kinds of Exim option:
5
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).
11
12This file was last updated for Exim release 4.72.

151. RUN TIME OPTIONS
16-------------------
17
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.
23
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 ++.
31
32For options that are specific to a particular driver, the fourth column
33contains the driver name, for example, appendfile. Otherwise, it contains
34
35 . `main' for options that appear in the main section of Exim's configuration
36 file;
37
38 . `authenticators' for generic options that apply to any authenticator;
39
40 . `routers' for generic options that apply to any router;
41
42 . `transports' for generic options that apply to any transport.
43
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.

7803. BUILD TIME OPTIONS FOR EXIM
781------------------------------
782
783The table below contains a "mostly" complete list of options that can be
784set in Local/Makefile when building Exim. The only items not included are
785those whose names can be trivially derived from rules stated below.
786
787More information about individual options can be found in src/EDITME and
788OS/Makefile-Default.
789
790The second column below gives the type of option:
791
792 . `system' means the option is concerned with the operating system;
793
794 . `driver' means the option selects a driver to be included in the binary;
795
796 . `lookup' means the option selects a lookuptype to be included in the binary;
797
798 . `mandatory' means the option is required to be supplied;
799
800 . `recommended' means the option is recommended to be supplied;
801
802 . `optional' means what it says;
803
804Those marked with * are specialized and are unlikely to be required in most
805installations. Those that are marked with ** are commonly set in OS-specific
806Makefiles. If you use any of these in your Local/Makefile, you may need to
807reproduce some of the OS-specific settings. For example, in the Makefile for
808Solaris (which is actually called OS/Makefile-SunOS5), there is
809
810 LIBS=-lsocket -lnsl -lkstat
811
812If you use LIBS to add extra libraries, you must also include the OS ones in
813your setting. It is better, in this particular case, to use EXTRALIBS, which is
814empty by default, and is provided for just this reason. Of course, if you do
815actually want to modify a setting from the OS-specific file, there is nothing
816to stop you overriding it in your Local/Makefile.
817
818When building Exim with dynamically loaded lookup support, for "LOOKUP_FOO",
819you can define "LOOKUP_FOO_INCLUDE" and "LOOKUP_FOO_LIBS", for includes and
820libraries specific only to that module. These rules are only used where the
821relevant lookup is a module. These options are not explicitly listed below.
822
823Variables with names endined `_PC' are used for pkg-config integration; setting
824the value to the name of a pkg-config package will cause Exim's build system to
825query the --cflags and --libs for the given name, when building anything
826dependent upon the component associated with the `_PC' variable. For lookups,
827if the lookup is dynamically loaded, then this *replaces* the use of the
828corresponding _INCLUDE and _LIBS options, which will be ignored. If the lookup
829is statically loaded into Exim, the results will be inserted into the
830"LOOKUP_INCLUDE" and "LOOKUP_LIBS" options. For authenticator, the results
831will be inserted into the "CFLAGS" and "AUTH_LIBS" options. These options are
832only listed below for the TLS implementation cases.

10124. BUILD TIME OPTIONS FOR EXIMON
1013--------------------------------
1014
1015The table below contains a complete list of options that can be set in
1016Local/eximon.conf when building the Exim monitor. Where the default is shown as
1017** it means that the text string is too long to fit in the table and is instead
1018given below. A blank default means that there is no default value.
1019
1020ACTION_OUTPUT=no show output for every action
1021ACTION_QUEUE_UPDATE=yes update queue display after actions
1022BODY_MAX=20000 maximum body display
1023DOMAIN= domain to strip from window title
1024LOG_BUFFER=20K buffer for log tail
1025LOG_DEPTH=300 depth of log subwindow
1026LOG_FONT=** font for log display
1027LOG_STRIPCHARTS=** patterns for stripcharts
1028LOG_WIDTH=950 width of log subwindow
1029MENU_EVENT='Shift<Btn1Down>' keypress for menu
1030MIN_HEIGHT=162 minimum window height
1031MIN_WIDTH=103 minimum window width
1032QUALIFY_DOMAIN= local domain to strip from addresses
1033QUEUE_DEPTH=200 depth of queue subwindow
1034QUEUE_FONT=$LOG_FONT font for queue display
1035QUEUE_INTERVAL=300 queue refresh interval
1036QUEUE_MAX_ADDRESSES=10 max addresses to show in queue
1037QUEUE_STRIPCHART_NAME=queue name for queue stripchart
1038QUEUE_WIDTH=950 width of queue subwindow
1039SIZE_STRIPCHART= request partition size stripchart
1040SIZE_STRIPCHART_NAME=space name for size stripchart
1041START_SMALL=no if yes, start with small window
1042STRIPCHART_INTERVAL=60 stripchart refresh interval
1043TEXT_DEPTH=200 depth of text windows
1044WINDOW_TITLE="${hostname} eximon" window title
1045
1046The default for LOG_FONT is
1047
1048 LOG_FONT=-misc-fixed-medium-r-normal-*-14-140-*-*-*-*-iso8859-1
1049
1050and the default for LOG_STRIPCHARTS is
1051
1052 LOG_STRIPCHARTS='/ <= /in/
1053 / => /out/
1054 / => .+ R=local/local/
1055 / => .+ T=[^ ]*smtp/smtp/'
1056
1057That is, there are four stripcharts, named in, out, local, and smtp. The first
1058counts message arrivals, the second counts all deliveries, the third counts
1059deliveries where the router's name starts with "local", and the fourth counts
1060deliveries where the transport name contains "smtp".
