RELOCATED(5)                                         RELOCATED(5)
       relocated - format of Postfix relocated table
       postmap /etc/postfix/relocated
       The optional relocated table provides the information that
       is used in "user has moved to  new_location"  bounce  mes-
       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.
       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:
              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.
              Matches every address in domain. This form has  the
              lowest precedence.
       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
       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
       Patterns  are  applied  in  the  order as specified in the
       table, until a pattern is found that  matches  the  search
       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.
       The  table format does not understand quoting conventions.
       The following parameters are  especially  relevant
       to  this  topic.  See  the Postfix file for syntax
       details and for default values.  Use  the  postfix  reload
       command after a configuration change.
