RELOCATED(5)                                         RELOCATED(5)

<b>NAME</b>
       relocated - format of Postfix relocated table

<b>SYNOPSIS</b>
       <b>postmap /etc/postfix/relocated</b>

<b>DESCRIPTION</b>
       The optional <b>relocated</b> table provides the information that
       is used in "user has moved to  <i>new</i><b>_</b><i>location</i>"  bounce  mes-
       sages.

       Normally,  the <b>relocated</b> table is specified as a text file
       that serves as  input  to  the  <a href="postmap.1.html"><b>postmap</b>(1)</a>  command.   The
       result,  an  indexed file in <b>dbm</b> or <b>db</b> format, is used for
       fast searching by the mail  system.  Execute  the  command
       <b>postmap  /etc/postfix/relocated</b>  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, or lookups can be directed to TCP-based server.  In
       that  case,  the  lookups are done in a slightly different
       way as described below under "REGULAR  EXPRESSION  TABLES"
       and "TCP-BASED TABLES".

       Table lookups are case insensitive.

<b>TABLE FORMAT</b>
       The input format for the <a href="postmap.1.html"><b>postmap</b>(1)</a> command is as follows:

       <b>o</b>      An entry has one of the following form:
                   <i>pattern      new</i><b>_</b><i>location</i>
              Where <i>new</i><b>_</b><i>location</i>  specifies  contact  information
              such  as  an  email  address,  or  perhaps a street
              address or telephone number.

       <b>o</b>      Empty lines and whitespace-only lines are  ignored,
              as  are  lines whose first non-whitespace character
              is a `#'.

       <b>o</b>      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:

       <i>user</i>@<i>domain</i>
              Matches <i>user</i>@<i>domain</i>. This form has precedence  over
              all other forms.

       <i>user</i>   Matches <i>user</i>@<i>site</i> when <i>site</i> is $<b><a href="postconf.5.html#myorigin">myorigin</a></b>, when <i>site</i>
              is listed in $<b><a href="postconf.5.html#mydestination">mydestination</a></b>, or when <i>site</i> is listed
              in $<b><a href="postconf.5.html#inet_interfaces">inet_interfaces</a></b> or $<b><a href="postconf.5.html#proxy_interfaces">proxy_interfaces</a></b>.

       @<i>domain</i>
              Matches  every address in <i>domain</i>. This form has the
              lowest precedence.

<b>ADDRESS EXTENSION</b>
       When a mail address localpart contains the optional recip-
       ient  delimiter  (e.g., <i>user+foo</i>@<i>domain</i>), the lookup order
       becomes: <i>user+foo</i>@<i>domain</i>, <i>user</i>@<i>domain</i>, <i>user+foo</i>, <i>user</i>, and
       @<i>domain</i>.

<b>REGULAR EXPRESSION TABLES</b>
       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
       <a href="regexp_table.5.html"><b>regexp_table</b>(5)</a> or <a href="pcre_table.5.html"><b>pcre_table</b>(5)</a>. For a description of the
       TCP client/server table lookup protocol, see <b>tcp_table</b>(5).

       Each  pattern  is  a regular expression that is applied to
       the entire address being looked up. Thus, <i>user@domain</i> mail
       addresses  are  not  broken up into their <i>user</i> and <i>@domain</i>
       constituent parts, nor is <i>user+foo</i> broken up into <i>user</i> and
       <i>foo</i>.

       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 <b>$1</b>, <b>$2</b> and so on.

<b>TCP-BASED TABLES</b>
       This  section  describes how the table lookups change when
       lookups are directed to a TCP-based server. For a descrip-
       tion   of  the  TCP  client/server  lookup  protocol,  see
       <b>tcp_table</b>(5).  This feature is not  available  in  Postfix
       version 2.1.

       Each lookup operation uses the entire address once.  Thus,
       <i>user@domain</i> mail addresses are not broken  up  into  their
       <i>user</i> and <i>@domain</i> constituent parts, nor is <i>user+foo</i> broken
       up into <i>user</i> and <i>foo</i>.

       Results are the same as with indexed file lookups.

<b>BUGS</b>
       The table format does not understand quoting  conventions.

<b>CONFIGURATION PARAMETERS</b>
       The  following <b>main.cf</b> parameters are especially relevant.
       The text below provides  only  a  parameter  summary.  See
