    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 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.

           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 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.
