RELOCATED(5) File Formats Manual RELOCATED(5) NAME relocated - Postfix relocated table format SYNOPSIS postmap /usr/local/etc/postfix/relocated DESCRIPTION The optional relocated(5) table provides the information that is used in "user has moved to new_location" bounce messages. Normally, the relocated(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. Ex- ecute the command "postmap /usr/local/etc/postfix/relocated" to rebuild an indexed file after changing the corresponding 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 expressions, or lookups can be di- rected to a TCP-based server. In those case, the lookups are done in a slightly different way as described below under "REGULAR EXPRESSION TA- BLES" or "TCP-BASED TABLES". Table lookups are case insensitive. 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: • An entry has one of the following form: pattern new_location Where new_location specifies contact information such as an email address, or perhaps a street address or telephone number. • Empty lines and whitespace-only lines are ignored, as are lines whose first non-whitespace character is a `#'. • A logical line starts with non-whitespace text. A line that starts with whitespace continues a logical line. TABLE SEARCH ORDER With lookups from indexed files such as DB or DBM, or from networked tables such as NIS, LDAP or SQL, patterns are tried in the order as listed below: 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 in $inet_interfaces or $proxy_interfaces. @domain Matches other addresses in domain. This form has the lowest precedence. ADDRESS EXTENSION When a mail address localpart contains the optional recipient delimiter (e.g., user+foo@domain), the lookup order becomes: user+foo@domain, user@domain, user+foo, user, and @domain. REGULAR EXPRESSION TABLES This section describes how the table lookups change when the table is given in the form of regular expressions or when lookups are directed to a TCP-based server. For a description of regular expression lookup table syntax, see regexp_table(5) or pcre_table(5). For a description of the TCP client/server table lookup protocol, see tcp_table(5). This feature is available in Postfix 2.5 and later. Each pattern is a regular expression that is applied to the entire ad- dress being looked up. Thus, user@domain mail addresses are not broken up into their user and @domain constituent parts, nor is user+foo bro- ken 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 indexed file lookups, with the additional feature that parenthesized substrings from the pattern can be interpo- lated as $1, $2 and so on. TCP-BASED TABLES This section describes how the table lookups change when lookups are directed to a TCP-based server. For a description of the TCP client/server lookup protocol, see tcp_table(5). This feature is available in Postfix 2.5 and later. Each lookup operation uses the entire address once. Thus, user@domain mail addresses are not broken up into their user and @domain con- stituent parts, nor is user+foo broken up into user and foo. Results are the same as with indexed file lookups. BUGS The table format does not understand quoting conventions. CONFIGURATION PARAMETERS The following main.cf parameters are especially relevant. The text be- low provides only a parameter summary. See postconf(5) for more details including examples. relocated_maps (empty) Optional lookup tables with new contact information for users or domains that no longer exist. Other parameters of interest: inet_interfaces (all) The local network interface addresses that this mail system re- ceives mail on. mydestination ($myhostname, localhost.$mydomain, localhost) The list of domains that are delivered via the $local_transport mail delivery transport. myorigin ($myhostname) The domain name that locally-posted mail appears to come from, and that locally posted mail is delivered to. proxy_interfaces (empty) The remote network interface addresses that this mail system re- ceives mail on by way of a proxy or network address translation unit.
