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.

7503. BUILD TIME OPTIONS FOR EXIM
751------------------------------
752
76ba6b0a
PP
753The table below contains a "mostly" complete list of options that can be
754set in Local/Makefile when building Exim. The only items not included are
755those whose names can be trivially derived from rules stated below.
756
757More information about individual options can be found in src/EDITME and
758OS/Makefile-Default.
495ae4b0
PH
759
760The second column below gives the type of option:
761
762 . `system' means the option is concerned with the operating system;
763
764 . `driver' means the option selects a driver to be included in the binary;
765
766 . `lookup' means the option selects a lookuptype to be included in the binary;
767
768 . `mandatory' means the option is required to be supplied;
769
770 . `recommended' means the option is recommended to be supplied;
771
772 . `optional' means what it says;
773
774Those marked with * are specialized and are unlikely to be required in most
775installations. Those that are marked with ** are commonly set in OS-specific
776Makefiles. If you use any of these in your Local/Makefile, you may need to
777reproduce some of the OS-specific settings. For example, in the Makefile for
778Solaris (which is actually called OS/Makefile-SunOS5), there is
779
780 LIBS=-lsocket -lnsl -lkstat
781
782If you use LIBS to add extra libraries, you must also include the OS ones in
783your setting. It is better, in this particular case, to use EXTRALIBS, which is
784empty by default, and is provided for just this reason. Of course, if you do
785actually want to modify a setting from the OS-specific file, there is nothing
786to stop you overriding it in your Local/Makefile.
787
76ba6b0a
PP
788When building Exim with dynamically loaded lookup support, for "LOOKUP_FOO",
789you can define "LOOKUP_FOO_INCLUDE" and "LOOKUP_FOO_LIBS", for includes and
790libraries specific only to that module. These rules are only used where the
791relevant lookup is a module. These options are not explicitly listed below.
792
793Variables with names endined `_PC' are used for pkg-config integration; setting
794the value to the name of a pkg-config package will cause Exim's build system to
795query the --cflags and --libs for the given name, when building anything
796dependent upon the component associated with the `_PC' variable. For lookups,
797if the lookup is dynamically loaded, then this *replaces* the use of the
798corresponding _INCLUDE and _LIBS options, which will be ignored. If the lookup
799is statically loaded into Exim, the results will be inserted into the
800"LOOKUP_INCLUDE" and "LOOKUP_LIBS" options. For authenticator, the results
801will be inserted into the "CFLAGS" and "AUTH_LIBS" options. These options are
802only listed below for the TLS implementation cases.

9824. BUILD TIME OPTIONS FOR EXIMON
983--------------------------------
984
985The table below contains a complete list of options that can be set in
986Local/eximon.conf when building the Exim monitor. Where the default is shown as
987** it means that the text string is too long to fit in the table and is instead
988given below. A blank default means that there is no default value.
989
990ACTION_OUTPUT=no show output for every action
991ACTION_QUEUE_UPDATE=yes update queue display after actions
992BODY_MAX=20000 maximum body display
993DOMAIN= domain to strip from window title
994LOG_BUFFER=20K buffer for log tail
995LOG_DEPTH=300 depth of log subwindow
996LOG_FONT=** font for log display
997LOG_STRIPCHARTS=** patterns for stripcharts
998LOG_WIDTH=950 width of log subwindow
999MENU_EVENT='Shift<Btn1Down>' keypress for menu
1000MIN_HEIGHT=162 minimum window height
1001MIN_WIDTH=103 minimum window width
1002QUALIFY_DOMAIN= local domain to strip from addresses
1003QUEUE_DEPTH=200 depth of queue subwindow
1004QUEUE_FONT=$LOG_FONT font for queue display
1005QUEUE_INTERVAL=300 queue refresh interval
1006QUEUE_MAX_ADDRESSES=10 max addresses to show in queue
1007QUEUE_STRIPCHART_NAME=queue name for queue stripchart
1008QUEUE_WIDTH=950 width of queue subwindow
1009SIZE_STRIPCHART= request partition size stripchart
1010SIZE_STRIPCHART_NAME=space name for size stripchart
1011START_SMALL=no if yes, start with small window
1012STRIPCHART_INTERVAL=60 stripchart refresh interval
1013TEXT_DEPTH=200 depth of text windows
1014WINDOW_TITLE="${hostname} eximon" window title
1015
1016The default for LOG_FONT is
1017
1018 LOG_FONT=-misc-fixed-medium-r-normal-*-14-140-*-*-*-*-iso8859-1
1019
1020and the default for LOG_STRIPCHARTS is
1021
1022 LOG_STRIPCHARTS='/ <= /in/
1023 / => /out/
1024 / => .+ R=local/local/
1025 / => .+ T=[^ ]*smtp/smtp/'
1026
1027That is, there are four stripcharts, named in, out, local, and smtp. The first
1028counts message arrivals, the second counts all deliveries, the third counts
1029deliveries where the router's name starts with "local", and the fourth counts
1030deliveries where the transport name contains "smtp".
