RELOCATED(5)                  File Formats Manual                 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:

       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 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.
