This is the opposite +# of canonical(5) mapping, which applies when mail is +# received. +# +# Typically, one would use the generic(5) table on a system +# that does not have a valid Internet domain name and that +# uses something like localdomain.local instead. The +# generic(5) table is then used by the smtp(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 generic(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 generic(5) table is specified as a text file +# that serves as input to the postmap(1) command. The +# result, an indexed file in dbm or db format, is used for +# fast searching by the mail system. Execute the command +# "postmap /etc/postfix/generic" 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 regu- +# lar-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 +# 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 +# The input format for the postmap(1) command is as follows: +# +# pattern result +# When pattern matches a mail address, replace it by +# the corresponding result. +# +# blank lines and comments +# Empty lines and whitespace-only lines are ignored, +# as are lines whose first non-whitespace character +# is a `#'. +# +# multi-line text +# A logical line starts with non-whitespace text. A +# line that starts with whitespace continues a logi- +# cal line. +# +# TABLE SEARCH ORDER +# With lookups from indexed files such as DB or DBM, or from +# networked tables such as NIS, LDAP or SQL, each +# user@domain 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. +# +# user@domain address +# Replace user@domain by address. This form has the +# highest precedence. +# +# user address +# Replace user@site by address when site is equal to +# $myorigin, when site is listed in $mydestination, +# or when it is listed in $inet_interfaces or +# $proxy_interfaces. +# +# @domain address +# Replace other addresses in domain by address. This +# form has the lowest precedence. +# +# RESULT ADDRESS REWRITING +# The lookup result is subject to address rewriting: +# +# o When the result has the form @otherdomain, the +# result becomes the same user in otherdomain. +# +# o When "append_at_myorigin=yes", append "@$myorigin" +# to addresses without "@domain". +# +# o When "append_dot_mydomain=yes", append ".$mydomain" +# to addresses without ".domain". +# +# ADDRESS EXTENSION +# When a mail address localpart contains the optional recip- +# ient delimiter (e.g., user+foo@domain), the lookup order +# becomes: user+foo@domain, user@domain, user+foo, user, and +# @domain. +# +# The propagate_unmatched_extensions parameter controls +# whether an unmatched address extension (+foo) is propa- +# gated to the result of table lookup. +# +# REGULAR EXPRESSION TABLES +# 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 regexp_table(5) or pcre_table(5). +# +# Each pattern is a regular expression that is applied to +# the entire address being looked up. Thus, user@domain mail +# addresses are not broken up into their user and @domain +# constituent parts, nor is user+foo broken up into user and +# foo. +# +# Patterns are applied in the order as specified in the ta- +# ble, 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 $1, $2 and so on. +# +# TCP-BASED TABLES +# This section describes how the table lookups change when +# lookups are directed to a TCP-based server. For a descrip- +# tion of the TCP client/server lookup protocol, see tcp_ta- +# ble(5). This feature is available in Postfix 2.5 and +# later. +# +# Each lookup operation uses the entire address once. Thus, +# user@domain mail addresses are not broken up into their +# user and @domain constituent parts, nor is user+foo broken +# up into user and foo. +# +# Results are the same as with indexed file lookups. +# +# EXAMPLE +# The following shows a generic mapping with an indexed +# file. When mail is sent to a remote host via SMTP, this +# replaces his@localdomain.local by his ISP mail address, +# replaces her@localdomain.local by her ISP mail address, +# and replaces other local addresses by his ISP account, +# with an address extension of +local (this example assumes +# that the ISP supports "+" style address extensions). +# +# /etc/postfix/main.cf: +# smtp_generic_maps = hash:/etc/postfix/generic +# +# /etc/postfix/generic: +# his@localdomain.local hisaccount@hisisp.example +# her@localdomain.local heraccount@herisp.example +# @localdomain.local hisaccount+local@hisisp.example +# +# Execute the command "postmap /etc/postfix/generic" when- +# ever the table is changed. Instead of hash, some systems +# use dbm database files.
