RELOCATED(5) RELOCATED(5) NAME relocated - format of Postfix relocated table SYNOPSIS postmap /etc/postfix/relocated DESCRIPTION The optional relocated table provides the information that is used in "user has moved to new_location" bounce mes- sages. Normally, the relocated 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/relocated in order to rebuild the indexed file after changing the relocated table. 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 expres- sions. In that case, the lookups are done in a slightly different way as described below. Table lookups are case insensitive. TABLE FORMAT The format of the table is as follows: o Blank lines are ignored, as are lines beginning with `#'. o Lines that begin with whitespace continue the pre- vious line. o An entry has one of the following form: key new_location Where new_location specifies contact information such as an email address, or perhaps a street address or telephone number. With lookups from indexed files such as DB or DBM, or from networked tables such as NIS, LDAP or SQL, the key field is one of the following: user@domain Matches user@domain. This form has precedence over all other forms. user Matches user@site when site is $myorigin, when site is listed in $mydestination, or when site is listed 1 RELOCATED(5) RELOCATED(5) in $inet_interfaces. @domain Matches every address in domain. This form has the lowest precedence. ADDRESS EXTENSION When the search fails, and the address localpart contains the optional recipient delimiter (e.g., user+foo@domain), the search is repeated for the unextended address (e.g. user@domain). 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 table, until a pattern is found that matches the search string. Results are the same as with normal indexed file lookups, with the additional feature that parenthesized substrings from the pattern can be interpolated as $1, $2 and so on. BUGS The table format does not understand quoting conventions. CONFIGURATION PARAMETERS The following main.cf parameters are especially relevant to this topic. See the Postfix main.cf file for syntax details and for default values. Use the postfix reload command after a configuration change. relocated_maps List of lookup tables for relocated users or sites. Other parameters of interest: inet_interfaces The network interface addresses that this system receives mail on. mydestination List of domains that this mail system considers local. 2 RELOCATED(5) RELOCATED(5) myorigin The domain that is appended to locally-posted mail.
