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.
