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.

7513. BUILD TIME OPTIONS FOR EXIM
752------------------------------
753
76ba6b0a
PP
754The table below contains a "mostly" complete list of options that can be
755set in Local/Makefile when building Exim. The only items not included are
756those whose names can be trivially derived from rules stated below.
757
758More information about individual options can be found in src/EDITME and
759OS/Makefile-Default.
495ae4b0
PH
760
761The second column below gives the type of option:
762
763 . `system' means the option is concerned with the operating system;
764
765 . `driver' means the option selects a driver to be included in the binary;
766
767 . `lookup' means the option selects a lookuptype to be included in the binary;
768
769 . `mandatory' means the option is required to be supplied;
770
771 . `recommended' means the option is recommended to be supplied;
772
773 . `optional' means what it says;
774
775Those marked with * are specialized and are unlikely to be required in most
776installations. Those that are marked with ** are commonly set in OS-specific
777Makefiles. If you use any of these in your Local/Makefile, you may need to
778reproduce some of the OS-specific settings. For example, in the Makefile for
779Solaris (which is actually called OS/Makefile-SunOS5), there is
780
781 LIBS=-lsocket -lnsl -lkstat
782
783If you use LIBS to add extra libraries, you must also include the OS ones in
784your setting. It is better, in this particular case, to use EXTRALIBS, which is
785empty by default, and is provided for just this reason. Of course, if you do
786actually want to modify a setting from the OS-specific file, there is nothing
787to stop you overriding it in your Local/Makefile.
788
76ba6b0a
PP
789When building Exim with dynamically loaded lookup support, for "LOOKUP_FOO",
790you can define "LOOKUP_FOO_INCLUDE" and "LOOKUP_FOO_LIBS", for includes and
791libraries specific only to that module. These rules are only used where the
792relevant lookup is a module. These options are not explicitly listed below.
793
794Variables with names endined `_PC' are used for pkg-config integration; setting
795the value to the name of a pkg-config package will cause Exim's build system to
796query the --cflags and --libs for the given name, when building anything
797dependent upon the component associated with the `_PC' variable. For lookups,
798if the lookup is dynamically loaded, then this *replaces* the use of the
799corresponding _INCLUDE and _LIBS options, which will be ignored. If the lookup
800is statically loaded into Exim, the results will be inserted into the
801"LOOKUP_INCLUDE" and "LOOKUP_LIBS" options. For authenticator, the results
802will be inserted into the "CFLAGS" and "AUTH_LIBS" options. These options are
803only listed below for the TLS implementation cases.

9834. BUILD TIME OPTIONS FOR EXIMON
984--------------------------------
985
986The table below contains a complete list of options that can be set in
987Local/eximon.conf when building the Exim monitor. Where the default is shown as
988** it means that the text string is too long to fit in the table and is instead
989given below. A blank default means that there is no default value.
990
991ACTION_OUTPUT=no show output for every action
992ACTION_QUEUE_UPDATE=yes update queue display after actions
993BODY_MAX=20000 maximum body display
994DOMAIN= domain to strip from window title
995LOG_BUFFER=20K buffer for log tail
996LOG_DEPTH=300 depth of log subwindow
997LOG_FONT=** font for log display
998LOG_STRIPCHARTS=** patterns for stripcharts
999LOG_WIDTH=950 width of log subwindow
1000MENU_EVENT='Shift<Btn1Down>' keypress for menu
1001MIN_HEIGHT=162 minimum window height
1002MIN_WIDTH=103 minimum window width
1003QUALIFY_DOMAIN= local domain to strip from addresses
1004QUEUE_DEPTH=200 depth of queue subwindow
1005QUEUE_FONT=$LOG_FONT font for queue display
1006QUEUE_INTERVAL=300 queue refresh interval
1007QUEUE_MAX_ADDRESSES=10 max addresses to show in queue
1008QUEUE_STRIPCHART_NAME=queue name for queue stripchart
1009QUEUE_WIDTH=950 width of queue subwindow
1010SIZE_STRIPCHART= request partition size stripchart
1011SIZE_STRIPCHART_NAME=space name for size stripchart
1012START_SMALL=no if yes, start with small window
1013STRIPCHART_INTERVAL=60 stripchart refresh interval
1014TEXT_DEPTH=200 depth of text windows
1015WINDOW_TITLE="${hostname} eximon" window title
1016
1017The default for LOG_FONT is
1018
1019 LOG_FONT=-misc-fixed-medium-r-normal-*-14-140-*-*-*-*-iso8859-1
1020
1021and the default for LOG_STRIPCHARTS is
1022
1023 LOG_STRIPCHARTS='/ <= /in/
1024 / => /out/
1025 / => .+ R=local/local/
1026 / => .+ T=[^ ]*smtp/smtp/'
1027
1028That is, there are four stripcharts, named in, out, local, and smtp. The first
1029counts message arrivals, the second counts all deliveries, the third counts
1030deliveries where the router's name starts with "local", and the fourth counts
1031deliveries where the transport name contains "smtp".
