relocated - Postfix relocated table format


   postmap /etc/postfix/relocated


   The  optional  relocated(5) table provides the information that is used
   in "user has moved to new_location" bounce messages.

   Normally, the relocated(5) 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"  to rebuild an
   indexed file after changing the corresponding 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,  or  lookups  can  be
   directed  to TCP-based server. In those case, the lookups are done in a
   slightly different way as described  below  under  "REGULAR  EXPRESSION

   Table lookups are case insensitive.


   The  search string is folded to lowercase before database lookup. As of
   Postfix 2.3, the search string is not case folded with  database  types
   such  as  regexp: or pcre: whose lookup fields can match both upper and
   lower case.


   The input format for the postmap(1) command is as follows:

   *      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.

   *      Empty  lines and whitespace-only lines are ignored, as are lines
          whose first non-whitespace character is a `#'.

   *      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:

          Matches  user@domain.  This  form  has precedence over all other

   user   Matches user@site when site is $myorigin, when site is listed in
          $mydestination,  or  when  site is listed in $inet_interfaces or

          Matches other addresses in domain.  This  form  has  the  lowest


   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.


   This  section  describes how the table lookups change when the table is
   given in the form of regular expressions or when lookups  are  directed
   to  a  TCP-based server. For a description of regular expression lookup
   table syntax, see regexp_table(5) or pcre_table(5). For  a  description
   of the TCP client/server table lookup protocol, see tcp_table(5).  This
   feature is not available up to and including Postfix version 2.4.

   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.


   This section describes how the table lookups change  when  lookups  are
   directed   to  a  TCP-based  server.  For  a  description  of  the  TCP
   client/server lookup protocol, see tcp_table(5).  This feature  is  not
   available up to and including Postfix version 2.4.

   Each  lookup operation uses the entire address once.  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.

   Results are the same as with indexed file lookups.

   The  following  parameters  are especially relevant.  The text
   below provides only a  parameter  summary.  See  postconf(5)  for  more
   details including examples.

   Other parameters of interest:

          on.  You need to stop and  start  Postfix  when  this  parameter
