# RELOCATED(5) RELOCATED(5) # # NAME # relocated - Postfix relocated table format # # SYNOPSIS # postmap /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. Execute the command # "postmap /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 regu- # lar-expression map where patterns are given as regular # expressions, or lookups can be directed to TCP-based # server. In those case, the lookups are done in a slightly # different way as described below under "REGULAR EXPRESSION # TABLES" 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: # # o 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. # # 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. # # 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 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 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 not available up to and including Postfix # version 2.4. # # 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 not available up to and including # Postfix version 2.4. # # 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. # # BUGS # The table format does not understand quoting conventions. # # CONFIGURATION PARAMETERS # The following main.cf parameters are especially relevant. # The text below provides only a parameter summary. See # postconf(5) for more details including examples. # # 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. # # proxy_interfaces # Other interfaces that this machine receives mail on # by way of a proxy agent or network address transla- # tor. # # SEE ALSO # trivial-rewrite(8), address resolver # postmap(1), Postfix lookup table manager # postconf(5), configuration parameters # # README FILES # Use "postconf readme_directory" or "postconf html_direc- # tory" to locate this information. # DATABASE_README, Postfix lookup table overview # ADDRESS_REWRITING_README, address rewriting guide # # LICENSE # The Secure Mailer license must be distributed with this # software. # # AUTHOR(S) # Wietse Venema # IBM T.J.
