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. A line that +# starts with whitespace continues a logical line. +# TABLE SEARCH ORDER +# .ad +# .fi +# With lookups from indexed files such as DB or DBM, or from networked +# tables such as NIS, LDAP or SQL, each \fIuser\fR@\fIdomain\fR +# query produces a sequence of query patterns as described below. +# +# Each query pattern is sent to each specified lookup table +# before trying the next query pattern, until a match is +# found. +# .IP "\fIuser\fR@\fIdomain address\fR" +# Replace \fIuser\fR@\fIdomain\fR by \fIaddress\fR. This form +# has the highest precedence. +# .IP "\fIuser address\fR" +# Replace \fIuser\fR@\fIsite\fR by \fIaddress\fR when \fIsite\fR is +# equal to $\fBmyorigin\fR, when \fIsite\fR is listed in +# $\fBmydestination\fR, or when it is listed in $\fBinet_interfaces\fR +# or $\fBproxy_interfaces\fR. +# .IP "@\fIdomain address\fR" +# Replace other addresses in \fIdomain\fR by \fIaddress\fR. +# This form has the lowest precedence. +# RESULT ADDRESS REWRITING +# .ad +# .fi +# The lookup result is subject to address rewriting: +# .IP \(bu +# When the result has the form @\fIotherdomain\fR, the +# result becomes the same \fIuser\fR in \fIotherdomain\fR. +# .IP \(bu +# When "\fBappend_at_myorigin=yes\fR", append "\fB@$myorigin\fR" +# to addresses without "@domain". +# .IP \(bu +# When "\fBappend_dot_mydomain=yes\fR", append +# "\fB.$mydomain\fR" to addresses without ".domain". +# ADDRESS EXTENSION +# .fi +# .ad +# When a mail address localpart contains the optional recipient delimiter +# (e.g., \fIuser+foo\fR@\fIdomain\fR), the lookup order becomes: +# \fIuser+foo\fR@\fIdomain\fR, \fIuser\fR@\fIdomain\fR, \fIuser+foo\fR, +# \fIuser\fR, and @\fIdomain\fR. +# +# The \fBpropagate_unmatched_extensions\fR parameter controls whether +# an unmatched address extension (\fI+foo\fR) is propagated to the +# result of table lookup. +# REGULAR EXPRESSION TABLES +# .ad +# .fi +# This section describes how the table lookups change when the table +# is given in the form of regular expressions. 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. Thus, \fIuser@domain\fR mail addresses are not +# broken up into their \fIuser\fR and \fI@domain\fR constituent parts, +# nor is \fIuser+foo\fR broken up into \fIuser\fR and \fIfoo\fR. +# +# Patterns are applied in the order as specified in the table, until a +# pattern is found that matches the search string. +# +# Results are the same as with indexed file lookups, with +# the additional feature that parenthesized substrings from the +# pattern can be interpolated as \fB$1\fR, \fB$2\fR and so on. +# TCP-BASED TABLES +# .ad +# .fi +# This section describes how the table lookups change when lookups +# are directed to a TCP-based server. For a description of the TCP +# client/server lookup protocol, see \fBtcp_table\fR(5). +# This feature is available in Postfix 2.5 and later. +# +# Each lookup operation uses the entire address once.
