RELOCATED(5)                                         RELOCATED(5)


NAME
       relocated - format of Postfix relocated table

SYNOPSIS
       postmap /etc/postfix/relocated

DESCRIPTION
       The  optional relocated file provides the information that
       is used in "user has moved to  new_location"  bounce  mes-
       sages.

       Normally,  the file serves as input to the postmap(1) com-
       mand.  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 format of the table is as follows:

       o      Blank lines are ignored,  as  are  lines  beginning
              with `#'.

       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.

       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



                                                                1

              lowest precedence.

ADDRESS EXTENSION
       When  the search fails, and the address localpart contains
       the optional recipient delimiter (e.g.,  user+foo@domain),
       the  search  is  repeated for the unextended address (e.g.
       user@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 normal 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.

       mydestination
              List of domains that  this  mail  system  considers
              local.

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