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 messages.

       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  expressions.  In  that  case,  the
       lookups are done in a slightly different way as described below.

       Table lookups are case insensitive.


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.

       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.

       @domain
              Matches every address in domain. This form has the lowest prece-
              dence.


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. 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 bro-
       ken 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 interpo-
       lated 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 Postfix when this parameter
              changes.

       mydestination
              List of domains that this mail system considers local.

       myorigin
              The domain that is appended to locally-posted mail.
