    RELOCATED(5)                                         RELOCATED(5)

    NAME
           relocated - format of Postfix relocated table

    SYNOPSIS
           postmap /usr/local/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  /usr/local/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:

                  receives mail on.

           mydestination
                  List  of  domains  that  this mail system considers
