Execute the command +"\fBpostmap /etc/postfix/relocated\fR" 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. +.SH "CASE FOLDING" +.na +.nf +.ad +.fi +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. +.SH "TABLE FORMAT" +.na +.nf +.ad +.fi +The input format for the \fBpostmap\fR(1) command is as follows: +.IP \(bu +An entry has one of the following form: + +.nf + \fIpattern new_location\fR +.fi + +Where \fInew_location\fR specifies contact information such as +an email address, or perhaps a street address or telephone number. +.IP \(bu +Empty lines and whitespace\-only lines are ignored, as +are lines whose first non\-whitespace character is a `#'. +.IP \(bu +A logical line starts with non\-whitespace text. A line that +starts with whitespace continues a logical line. +.SH "TABLE SEARCH ORDER" +.na +.nf +.ad +.fi +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: +.IP \fIuser\fR@\fIdomain\fR +Matches \fIuser\fR@\fIdomain\fR. This form has precedence over all +other forms. +.IP \fIuser\fR +Matches \fIuser\fR@\fIsite\fR when \fIsite\fR is $\fBmyorigin\fR, +when \fIsite\fR is listed in $\fBmydestination\fR, or when \fIsite\fR +is listed in $\fBinet_interfaces\fR or $\fBproxy_interfaces\fR. +.IP @\fIdomain\fR +Matches other addresses in \fIdomain\fR. This form has the lowest +precedence. +.SH "ADDRESS EXTENSION" +.na +.nf +.fi +.ad +When a mail address localpart contains the optional recipient delimiter +(e.g., \fIuser+foo\fR@\fIdomain\fR), the lookup order becomes: +\fIuser+foo\fR@\fIdomain\fR, \fIuser\fR@\fIdomain\fR, \fIuser+foo\fR, +\fIuser\fR, and @\fIdomain\fR. +.SH "REGULAR EXPRESSION TABLES" +.na +.nf +.ad +.fi +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 \fBregexp_table\fR(5) or +\fBpcre_table\fR(5). For a description of the TCP client/server +table lookup protocol, see \fBtcp_table\fR(5). +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, \fIuser@domain\fR mail addresses are not +broken up into their \fIuser\fR and \fI@domain\fR constituent parts, +nor is \fIuser+foo\fR broken up into \fIuser\fR and \fIfoo\fR. + +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 \fB$1\fR, \fB$2\fR and so on. +.SH "TCP-BASED TABLES" +.na +.nf +.ad +.fi +This section describes how the table lookups change when lookups +are directed to a TCP\-based server. For a description of the TCP +client/server lookup protocol, see \fBtcp_table\fR(5). +This feature is available in Postfix 2.5 and later. + +Each lookup operation uses the entire address once. Thus, +\fIuser@domain\fR mail addresses are not broken up into their +\fIuser\fR and \fI@domain\fR constituent parts, nor is +\fIuser+foo\fR broken up into \fIuser\fR and \fIfoo\fR. + +Results are the same as with indexed file lookups. +.SH BUGS +.ad +.fi +The table format does not understand quoting conventions. +.SH "CONFIGURATION PARAMETERS" +.na +.nf +.ad +.fi +The following \fBmain.cf\fR parameters are especially relevant. +The text below provides only a parameter summary. See +\fBpostconf\fR(5) for more details including examples. +.IP "\fBrelocated_maps (empty)\fR" +Optional lookup tables with new contact information for users or +domains that no longer exist. +.PP +Other parameters of interest: +.IP "\fBinet_interfaces (all)\fR" +The network interface addresses that this mail system receives +mail on. +.IP "\fBmydestination ($myhostname, localhost.$mydomain, localhost)\fR" +The list of domains that are delivered via the $local_transport +mail delivery transport. +.IP "\fBmyorigin ($myhostname)\fR" +The domain name that locally\-posted mail appears to come +from, and that locally posted mail is delivered to. +.IP "\fBproxy_interfaces (empty)\fR" +The network interface addresses that this mail system receives mail +on by way of a proxy or network address translation unit. +.SH "SEE ALSO" +.na +.nf +trivial\-rewrite(8), address resolver +postmap(1), Postfix lookup table manager +postconf(5), configuration parameters +.SH "README FILES" +.na +.nf +.ad +.fi +Use "\fBpostconf readme_directory\fR" or +"\fBpostconf html_directory\fR" to locate this information. +.na +.nf +DATABASE_README, Postfix lookup table overview +ADDRESS_REWRITING_README, address rewriting guide +.SH "LICENSE" +.na +.nf +.ad +.fi +The Secure Mailer license must be distributed with this software. +.SH "AUTHOR(S)" +.na +.nf +Wietse Venema +IBM T.J.
