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 4.95.


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.

3. 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.

4. 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

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_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".
