These tables are usually in +# \fBdbm\fR or \fBdb\fR format. +# +# Alternatively, lookup tables can be specified as MySQL databases. +# In order to use MySQL lookups, define a MySQL source as a lookup +# table in main.cf, for example: +# .nf +# alias_maps = mysql:/etc/postfix/mysql-aliases.cf +# .fi +# +# The file /etc/postfix/mysql-aliases.cf has the same format as +# the Postfix main.cf file, and can specify the parameters +# described below. +# LIST MEMBERSHIP +# .ad +# .fi +# When using SQL to store lists such as $mynetworks, +# $mydestination, $relay_domains, $local_recipient_maps, +# etc., it is important to understand that the table must +# store each list member as a separate key. The table lookup +# verifies the *existence* of the key. See "Postfix lists +# versus tables" in the DATABASE_README document for a +# discussion. +# +# Do NOT create tables that return the full list of domains +# in $mydestination or $relay_domains etc., or IP addresses +# in $mynetworks. +# +# DO create tables with each matching item as a key and with +# an arbitrary value. With SQL databases it is not uncommon to +# return the key itself or a constant value. +# MYSQL PARAMETERS +# .ad +# .fi +# .IP "\fBhosts\fR" +# The hosts that Postfix will try to connect to and query from. +# Specify \fIunix:\fR for UNIX domain sockets, \fIinet:\fR for TCP +# connections (default).
