+RELOCATED(5) RELOCATED(5)
+
+<b>NAME</b>
+ relocated - Postfix relocated table format
+
+<b>SYNOPSIS</b>
+ <b>postmap /etc/postfix/relocated</b>
+
+<b>DESCRIPTION</b>
+ The optional <a href="relocated.5.html"><b>relocated</b>(5)</a> table provides the information that is used
+ in "user has moved to <i>new</i><b>_</b><i>location</i>" bounce messages.
+
+ Normally, the <a href="relocated.5.html"><b>relocated</b>(5)</a> 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>" 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 a 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.
+
+<b>CASE FOLDING</b>
+ 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 <a href="regexp_table.5.html">regexp</a>: or <a href="pcre_table.5.html">pcre</a>: whose lookup fields can match both upper and
+ lower case.
+
+<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 logical line.
+
+<b>TABLE SEARCH ORDER</b>
+ 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 other addresses in <i>domain</i>. This form has the lowest
+ precedence.
+
+<b>ADDRESS EXTENSION</b>
+ When a mail address localpart contains the optional recipient 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 <a href="tcp_table.5.html"><b>tcp_table</b>(5)</a>. This
+ feature is available in Postfix 2.5 and later.
+
+ 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 bro-
+ ken 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 interpo-
+ lated 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 description of the TCP
+ client/server lookup protocol, see <a href="tcp_table.5.html"><b>tcp_table</b>(5)</a>. This feature is
+ available in Postfix 2.5 and later.
+
+ 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> con-
+ stituent 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 <a href="postconf.5.html"><b>main.cf</b></a> parameters are especially relevant. The text
+ below provides only a parameter summary. See <a href="postconf.5.html"><b>postconf</b>(5)</a> for more
+ details including examples.
