# 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 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. # # o Empty lines and whitespace-only lines are ignored, # as are lines whose first non-whitespace character # is a `#'. # # o A logical line starts with non-whitespace text. A # line that starts with whitespace continues a logi- # cal line. # # 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 # in $inet_interfaces. # # @domain # Matches every address in domain. This form has the # lowest precedence. # # 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. # # 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 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. You need to stop and start Post- # fix when this parameter changes. # # mydestination # List of domains that this mail system considers # local. # # myorigin # The domain that is appended to locally-posted mail. # # SEE ALSO # postmap(1) create lookup table # pcre_table(5) format of PCRE tables # regexp_table(5) format of POSIX regular expression tables # # LICENSE # The Secure Mailer license must be distributed with this # software. # # AUTHOR(S) # Wietse Venema # IBM T.J.
