# These settings determine which file and database lookup methods are included

# LOOKUP_DNSDB does *not* refer to general mail routing using the DNS. It is
# for the specialist case of using the DNS as a general database facility (not
# common).
+# If set to "2" instead of "yes" then the corresponding lookup will be
+# built as a module and must be installed into LOOKUP_MODULE_DIR. You need to
+# add -export-dynamic -rdynamic to EXTRALIBS. You may also need to add -ldl to
+# EXTRALIBS so that dlopen() is available to Exim. You need to define
+# LOOKUP_MODULE_DIR above so the exim binary actually loads dynamic lookup
+# modules.
+# Also, instead of adding all the libraries/includes to LOOKUP_INCLUDE and
+# LOOKUP_LIBS, add them to the respective LOOKUP_*_INCLUDE and LOOKUP_*_LIBS
+# (where * is the name as given here in this list). That ensures that only
+# the dynamic library and not the exim binary will be linked against the
+# library.
+# NOTE: LDAP cannot be built as a module!

+# When a user other than root uses the -C option to override the configuration
+# file (including the Exim user when re-executing Exim to regain root
+# privileges for local message delivery), this will normally cause Exim to
+# drop root privileges. The TRUSTED_CONFIG_LIST option, specifies a file which
+# contains a list of trusted configuration filenames, one per line. If the -C
+# option is used by the Exim user or by the user specified in the
+# CONFIGURE_OWNER setting, to specify a configuration file which is listed in
+# the TRUSTED_CONFIG_LIST file, then root privileges are not dropped by Exim.

# Uncommenting this option disables the use of the -D command line option,
# which changes the values of macros in the runtime configuration file.
# DISABLE_D_OPTION=yes
+#------------------------------------------------------------------------------
+# By contrast, you might be maintaining a system which relies upon the ability
+# to override values with -D and assumes that these will be passed through to
+# the delivery processes. As of Exim 4.73, this is no longer the case by
+# default. Going forward, we strongly recommend that you use a shim Exim
+# configuration file owned by root stored under TRUSTED_CONFIG_LIST.
+# That shim can set macros before .include'ing your main configuration file.
+#
+# As a strictly transient measure to ease migration to 4.73, the
+# WHITELIST_D_MACROS value definies a colon-separated list of macro-names
+# which are permitted to be overriden from the command-line which will be
+# honoured by the Exim user. So these are macros that can persist to delivery
+# time.
+# Examples might be -DTLS or -DSPOOL=/some/dir. The values on the
+# command-line are filtered to only permit: [A-Za-z0-9_/.-]*
+#
+# This option is highly likely to be removed in a future release. It exists
+# only to make 4.73 as easy as possible to migrate to. If you use it, we
+# encourage you to schedule time to rework your configuration to not depend
+# upon it. Most people should not need to use this.
+#
+# By default, no macros are whitelisted for -D usage.
