RELOCATED(5)                  File Formats Manual                 RELOCATED(5)

NAME
       relocated - Postfix relocated table format
SYNOPSIS
       postmap /etc/postfix/relocated
DESCRIPTION
       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
       TABLES" or "TCP-BASED TABLES".
       Table lookups are case insensitive.
CASE FOLDING
       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.
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 logical line.
TABLE SEARCH ORDER
       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 or
              $proxy_interfaces.
       @domain
              Matches other addresses in domain.  This  form  has  the  lowest
              precedence.
ADDRESS EXTENSION
       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.
REGULAR EXPRESSION TABLES
       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 bro-
       ken 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 interpo-
       lated as $1, $2 and so on.
TCP-BASED TABLES
       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  con-
       stituent parts, nor is user+foo broken up into user and foo.
       Results are the same as with indexed file lookups.
BUGS
       The table format does not understand quoting conventions.
CONFIGURATION PARAMETERS
       The  following  main.cf  parameters  are especially relevant.  The text
       below provides only a  parameter  summary.  See  postconf(5)  for  more
       details including examples.
       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  Postfix  when  this  parameter
              changes.
       mydestination
              List of domains that this mail system considers local.
       myorigin
              The domain that is appended to locally-posted mail.
       proxy_interfaces
              Other  interfaces that this machine receives mail on by way of a
              proxy agent or network address translator.
