LISTS OF EXIM OPTIONS --------------------- This file contains an almost complete lists of four kinds of Exim option: 1. Those that can appear in the run time configuration file; 2. Those that can be used on the command line; 3. Those that can appear in the build time configuration (Local/Makefile); 4. Those that can appear in the build time configuration for the Exim monitor (Local/eximon.conf). This file was last updated for Exim release 4.99. 1. RUN TIME OPTIONS ------------------- As Exim has developed, new options have been added at each major release. For the most part, backwards compatibility has been maintained, and obsolete options continue to be recognized. However, incompatible changes took place at releases 3.00, and 4.00. In both cases, several groups of options were amalgamated into new, extended options, and obsolete options were removed. The table below contains a complete list of all Exim's current options, along with their types, default values, and where they can be used. String options that are expanded before use are marked with *. Host lists, domain lists, and address lists are always expanded. In some cases the defaults are not fixed values, or not short enough to fit in the table. These are indicated by +. Some other default values are determined when the Exim binary is compiled; these are indicated by ++. For options that are specific to a particular driver, the fourth column contains the driver name, for example, appendfile. Otherwise, it contains . `main' for options that appear in the main section of Exim's configuration file; . `authenticators' for generic options that apply to any authenticator; . `routers' for generic options that apply to any router; . `transports' for generic options that apply to any transport. The fifth column contains the version of Exim in which the option was added, or substantially changed. Where no number is given, the option has been in Exim since the very early releases. The routers were completely reorganised for release 4.00, and so no router options are shown as earlier than 4.00, though in fact some of them were inherited from earlier versions.

BUILD TIME OPTIONS FOR EXIM ------------------------------ The table below contains a "mostly" complete list of options that can be set in Local/Makefile when building Exim. The only items not included are those whose names can be trivially derived from rules stated below. More information about individual options can be found in src/EDITME and OS/Makefile-Default. The second column below gives the type of option: . `system' means the option is concerned with the operating system; . `driver' means the option selects a driver to be included in the binary; . `lookup' means the option selects a lookuptype to be included in the binary; . `mandatory' means the option is required to be supplied; . `recommended' means the option is recommended to be supplied; . `optional' means what it says; Those marked with * are specialized and are unlikely to be required in most installations. Those that are marked with ** are commonly set in OS-specific Makefiles. If you use any of these in your Local/Makefile, you may need to reproduce some of the OS-specific settings. For example, in the Makefile for Solaris (which is actually called OS/Makefile-SunOS5), there is LIBS=-lsocket -lnsl -lkstat If you use LIBS to add extra libraries, you must also include the OS ones in your setting. It is better, in this particular case, to use EXTRALIBS, which is empty by default, and is provided for just this reason. Of course, if you do actually want to modify a setting from the OS-specific file, there is nothing to stop you overriding it in your Local/Makefile. When building Exim with dynamically loaded lookup support, for "LOOKUP_FOO", you can define "LOOKUP_FOO_INCLUDE" and "LOOKUP_FOO_LIBS", for includes and libraries specific only to that module. These rules are only used where the relevant lookup is a module. These options are not explicitly listed below. Variables with names endined `_PC' are used for pkg-config integration; setting the value to the name of a pkg-config package will cause Exim's build system to query the --cflags and --libs for the given name, when building anything dependent upon the component associated with the `_PC' variable. For lookups, if the lookup is dynamically loaded, then this *replaces* the use of the corresponding _INCLUDE and _LIBS options, which will be ignored. If the lookup is statically loaded into Exim, the results will be inserted into the "LOOKUP_INCLUDE" and "LOOKUP_LIBS" options. For authenticator, the results will be inserted into the "CFLAGS" and "AUTH_LIBS" options. These options are only listed below for the TLS implementation cases.

BUILD TIME OPTIONS FOR EXIMON -------------------------------- The table below contains a complete list of options that can be set in Local/eximon.conf when building the Exim monitor. Where the default is shown as ** it means that the text string is too long to fit in the table and is instead given below. A blank default means that there is no default value. ACTION_OUTPUT=no show output for every action ACTION_QUEUE_UPDATE=yes update queue display after actions BODY_MAX=20000 maximum body display DOMAIN= domain to strip from window title LOG_BUFFER=20K buffer for log tail LOG_DEPTH=300 depth of log subwindow LOG_FONT=** font for log display LOG_STRIPCHARTS=** patterns for stripcharts LOG_WIDTH=950 width of log subwindow MENU_EVENT='Shift<Btn1Down>' keypress for menu MIN_HEIGHT=162 minimum window height MIN_WIDTH=103 minimum window width QUALIFY_DOMAIN= local domain to strip from addresses QUEUE_DEPTH=200 depth of queue subwindow QUEUE_FONT=$LOG_FONT font for queue display QUEUE_INTERVAL=300 queue refresh interval QUEUE_MAX_ADDRESSES=10 max addresses to show in queue QUEUE_STRIPCHART_NAME=queue name for queue stripchart QUEUE_WIDTH=950 width of queue subwindow SIZE_STRIPCHART= request partition size stripchart SIZE_STRIPCHART_NAME=space name for size stripchart START_SMALL=no if yes, start with small window STRIPCHART_INTERVAL=60 stripchart refresh interval TEXT_DEPTH=200 depth of text windows WINDOW_TITLE="${hostname} eximon" window title The default for LOG_FONT is LOG_FONT=-misc-fixed-medium-r-normal-*-14-140-*-*-*-*-iso8859-1 and the default for LOG_STRIPCHARTS is LOG_STRIPCHARTS='/ <= /in/ / => /out/ / => .+ R=local/local/ / => .+ T=[^ ]*smtp/smtp/' That is, there are four stripcharts, named in, out, local, and smtp. The first counts message arrivals, the second counts all deliveries, the third counts deliveries where the router's name starts with "local", and the fourth counts deliveries where the transport name contains "smtp". **** End of OptionLists ****
