4 This 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
12 This file was last updated for Exim release 4.72.
18 As Exim has developed, new options have been added at each major release. For
19 the most part, backwards compatibility has been maintained, and obsolete
20 options continue to be recognized. However, incompatible changes took place at
21 releases 3.00, and 4.00. In both cases, several groups of options were
22 amalgamated into new, extended options, and obsolete options were removed.
24 The table below contains a complete list of all Exim's current options, along
25 with their types, default values, and where they can be used. String options
26 that are expanded before use are marked with *. Host lists, domain lists, and
27 address lists are always expanded. In some cases the defaults are not fixed
28 values, or not short enough to fit in the table. These are indicated by +. Some
29 other default values are determined when the Exim binary is compiled; these are
32 For options that are specific to a particular driver, the fourth column
33 contains the driver name, for example, appendfile. Otherwise, it contains
35 . `main' for options that appear in the main section of Exim's configuration
38 . `authenticators' for generic options that apply to any authenticator;
40 . `routers' for generic options that apply to any router;
42 . `transports' for generic options that apply to any transport.
44 The fifth column contains the version of Exim in which the option was added, or
45 substantially changed. Where no number is given, the option has been in Exim
46 since the very early releases. The routers were completely reorganised for
47 release 4.00, and so no router options are shown as earlier than 4.00, though
48 in fact some of them were inherited from earlier versions.

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

942 4. BUILD TIME OPTIONS FOR EXIMON
943 --------------------------------
945 The table below contains a complete list of options that can be set in
946 Local/eximon.conf when building the Exim monitor. Where the default is shown as
947 ** it means that the text string is too long to fit in the table and is instead
948 given below. A blank default means that there is no default value.
950 ACTION_OUTPUT=no show output for every action
951 ACTION_QUEUE_UPDATE=yes update queue display after actions
952 BODY_MAX=20000 maximum body display
953 DOMAIN= domain to strip from window title

956 LOG_FONT=** font for log display
957 LOG_STRIPCHARTS=** patterns for stripcharts
958 LOG_WIDTH=950 width of log subwindow
959 MENU_EVENT='Shift<Btn1Down>' keypress for menu
960 MIN_HEIGHT=162 minimum window height
961 MIN_WIDTH=103 minimum window width
962 QUALIFY_DOMAIN= local domain to strip from addresses
963 QUEUE_DEPTH=200 depth of queue subwindow
964 QUEUE_FONT=$LOG_FONT font for queue display

966 QUEUE_MAX_ADDRESSES=10 max addresses to show in queue
967 QUEUE_STRIPCHART_NAME=queue name for queue stripchart
968 QUEUE_WIDTH=950 width of queue subwindow
969 SIZE_STRIPCHART= request partition size stripchart
970 SIZE_STRIPCHART_NAME=space name for size stripchart

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