This is the +# opposite of \fBcanonical\fR(5) mapping, which applies when +# mail is received. +# +# Typically, one would use the \fBgeneric\fR(5) table on a +# system that does not have a valid Internet domain name and +# that uses something like \fIlocaldomain.local\fR instead. +# The \fBgeneric\fR(5) table is then used by the \fBsmtp\fR(8) +# client to transform local mail addresses into valid Internet +# mail addresses when mail has to be sent across the Internet. +# See the EXAMPLE section at the end of this document. +# +# The \fBgeneric\fR(5) mapping affects both message header +# addresses (i.e. addresses that appear inside messages) and +# message envelope addresses (for example, the addresses that +# are used in SMTP protocol commands). +# +# Normally, the \fBgeneric\fR(5) table is specified as a +# text file that serves as input to the \fBpostmap\fR(1) +# command. The result, an indexed file in \fBdbm\fR or +# \fBdb\fR format, is used for fast searching by the mail +# system. Execute the command "\fBpostmap /etc/postfix/generic\fR" +# to rebuild an indexed file after changing the corresponding +# text file. +# +# When the table is provided via other means such as NIS, LDAP +# or SQL, the same lookups are done as for ordinary indexed files. +# +# Alternatively, the table can be provided as a regular-expression +# map where patterns are given as regular expressions, or lookups +# can be directed to a TCP-based server. In those cases, the lookups +# are done in a slightly different way as described below under +# "REGULAR EXPRESSION TABLES" or "TCP-BASED TABLES". +# CASE FOLDING +# .ad +# .fi +# The search string is folded to lowercase before database +# lookup. As of Postfix 2.3, the search string is not case +# folded with database types such as regexp: or pcre: whose +# lookup fields can match both upper and lower case. +# TABLE FORMAT +# .ad +# .fi +# The input format for the \fBpostmap\fR(1) command is as follows: +# .IP "\fIpattern result\fR" +# When \fIpattern\fR matches a mail address, replace it by the +# corresponding \fIresult\fR. +# .IP "blank lines and comments" +# Empty lines and whitespace-only lines are ignored, as +# are lines whose first non-whitespace character is a `#'. +# .IP "multi-line text" +# A logical line starts with non-whitespace text.

For a description of +# regular expression lookup table syntax, see \fBregexp_table\fR(5) +# or \fBpcre_table\fR(5). +# +# Each pattern is a regular expression that is applied to the entire +# address being looked up.
