+# If not using package management but using this anyway, then think about how
+# you perform upgrades and revert them. You should consider the benefit of
+# embedding the Exim version number into LOOKUP_MODULE_DIR, so that you can
+# maintain two concurrent sets of modules.
+
+# To build a module dynamically, you'll need to define CFLAGS_DYNAMIC for
+# your platform. Eg:
+# CFLAGS_DYNAMIC=-shared -rdynamic
+# CFLAGS_DYNAMIC=-shared -rdynamic -fPIC

#------------------------------------------------------------------------------
# These settings determine which file and database lookup methods are included
# in the binary. See the manual chapter entitled "File and database lookups"
# 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!

+# Expanding match_* second paramters: BE CAREFUL IF ENABLING THIS!
+# It has proven too easy in practice for administrators to configure security
+# problems into their Exim install, by treating match_domain{}{} and friends
+# as a form of string comparison, where the second string comes from untrusted
+# data. Because these options take lists, which can include lookup;LOOKUPDATA
+# style elements, a foe can then cause Exim to, eg, execute an arbitrary MySQL
+# query, dropping tables.
+# From Exim 4.77 onwards, the second parameter is not expanded; it can still
+# be a list literal, or a macro, or a named list reference. There is also
+# the new expansion condition "inlisti" which does expand the second parameter,
+# but treats it as a list of strings; also, there's "eqi" which is probably
+# what is normally wanted.
+#
+# If you really need to have the old behaviour, know what you are doing and
+# will not complain if your system is compromised as a result of doing so, then
+# uncomment this option to get the old behaviour back.
