1LISTS OF EXIM OPTIONS

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).

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.

7443. BUILD TIME OPTIONS FOR EXIM
745------------------------------
746
76ba6b0a
PP
747The table below contains a "mostly" complete list of options that can be
748set in Local/Makefile when building Exim. The only items not included are
749those whose names can be trivially derived from rules stated below.
750
751More information about individual options can be found in src/EDITME and
752OS/Makefile-Default.
495ae4b0
PH
753
754The second column below gives the type of option:
755
756 . `system' means the option is concerned with the operating system;
757
758 . `driver' means the option selects a driver to be included in the binary;
759
760 . `lookup' means the option selects a lookuptype to be included in the binary;
761
762 . `mandatory' means the option is required to be supplied;
763
764 . `recommended' means the option is recommended to be supplied;
765
766 . `optional' means what it says;
767
768Those marked with * are specialized and are unlikely to be required in most
769installations. Those that are marked with ** are commonly set in OS-specific
770Makefiles. If you use any of these in your Local/Makefile, you may need to
771reproduce some of the OS-specific settings. For example, in the Makefile for
772Solaris (which is actually called OS/Makefile-SunOS5), there is
773
774 LIBS=-lsocket -lnsl -lkstat
775
776If you use LIBS to add extra libraries, you must also include the OS ones in
777your setting. It is better, in this particular case, to use EXTRALIBS, which is
778empty by default, and is provided for just this reason. Of course, if you do
779actually want to modify a setting from the OS-specific file, there is nothing
780to stop you overriding it in your Local/Makefile.
781
76ba6b0a
PP
782When building Exim with dynamically loaded lookup support, for "LOOKUP_FOO",
783you can define "LOOKUP_FOO_INCLUDE" and "LOOKUP_FOO_LIBS", for includes and
784libraries specific only to that module. These rules are only used where the
785relevant lookup is a module. These options are not explicitly listed below.
786
787Variables with names endined `_PC' are used for pkg-config integration; setting
788the value to the name of a pkg-config package will cause Exim's build system to
789query the --cflags and --libs for the given name, when building anything
790dependent upon the component associated with the `_PC' variable. For lookups,
791if the lookup is dynamically loaded, then this *replaces* the use of the
792corresponding _INCLUDE and _LIBS options, which will be ignored. If the lookup
793is statically loaded into Exim, the results will be inserted into the
794"LOOKUP_INCLUDE" and "LOOKUP_LIBS" options. For authenticator, the results
795will be inserted into the "CFLAGS" and "AUTH_LIBS" options. These options are
796only listed below for the TLS implementation cases.

9754. BUILD TIME OPTIONS FOR EXIMON
976--------------------------------
977
978The table below contains a complete list of options that can be set in
979Local/eximon.conf when building the Exim monitor. Where the default is shown as
980** it means that the text string is too long to fit in the table and is instead
981given below. A blank default means that there is no default value.
982
983ACTION_OUTPUT=no show output for every action
984ACTION_QUEUE_UPDATE=yes update queue display after actions
985BODY_MAX=20000 maximum body display
986DOMAIN= domain to strip from window title
987LOG_BUFFER=20K buffer for log tail
988LOG_DEPTH=300 depth of log subwindow
989LOG_FONT=** font for log display
990LOG_STRIPCHARTS=** patterns for stripcharts
991LOG_WIDTH=950 width of log subwindow
992MENU_EVENT='Shift<Btn1Down>' keypress for menu
993MIN_HEIGHT=162 minimum window height
994MIN_WIDTH=103 minimum window width
995QUALIFY_DOMAIN= local domain to strip from addresses
996QUEUE_DEPTH=200 depth of queue subwindow
997QUEUE_FONT=$LOG_FONT font for queue display
998QUEUE_INTERVAL=300 queue refresh interval
999QUEUE_MAX_ADDRESSES=10 max addresses to show in queue
1000QUEUE_STRIPCHART_NAME=queue name for queue stripchart
1001QUEUE_WIDTH=950 width of queue subwindow
1002SIZE_STRIPCHART= request partition size stripchart
1003SIZE_STRIPCHART_NAME=space name for size stripchart
1004START_SMALL=no if yes, start with small window
1005STRIPCHART_INTERVAL=60 stripchart refresh interval
1006TEXT_DEPTH=200 depth of text windows
1007WINDOW_TITLE="${hostname} eximon" window title
1008
1009The default for LOG_FONT is
1010
1011 LOG_FONT=-misc-fixed-medium-r-normal-*-14-140-*-*-*-*-iso8859-1
1012
1013and the default for LOG_STRIPCHARTS is
1014
1015 LOG_STRIPCHARTS='/ <= /in/
1016 / => /out/
1017 / => .+ R=local/local/
1018 / => .+ T=[^ ]*smtp/smtp/'
1019
1020That is, there are four stripcharts, named in, out, local, and smtp. The first
1021counts message arrivals, the second counts all deliveries, the third counts
1022deliveries where the router's name starts with "local", and the fourth counts
1023deliveries where the transport name contains "smtp".
