RELOCATED(5) RELOCATED(5)

NAME

relocated - format of Postfix relocated table

SYNOPSIS

ppoossttmmaapp //eettcc//ppoossttffiixx//rreellooccaatteedd

DESCRIPTION

The optional rreellooccaatteedd table provides the information that is used in "user has moved to newlocation" bounce messages. Normally, the rreellooccaatteedd table is specified as a text file that serves as input to the ppoossttmmaapp(1) command. The result, an indexed file in ddbbmm or ddbb format, is used for fast searching by the mail system. Execute the command ppoossttmmaapp //eettcc//ppoossttffiixx//rreellooccaatteedd 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 expressions, 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. TTAABBLLEE FFOORRMMAATT The input format for the ppoossttmmaapp(1) command is as follows: +o An entry has one of the following form: pattern newlocation Where newlocation 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. 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 $mmyyoorriiggiinn, when site is listed in

$mmyyddeessttiinnaattiioonn, or when site is listed in $iinneettiinntteerrffaacceess or

$pprrooxxyyiinntteerrffaacceess.

@domain

Matches every address in domain. This form has the lowest prece-

dence. AADDDDRREESSSS EEXXTTEENNSSIIOONN 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. RREEGGUULLAARR EEXXPPRREESSSSIIOONN TTAABBLLEESS 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 rreeggeexxppttaabbllee(5) or ppccrreettaabbllee(5). For a description of the TCP client/server table lookup protocol, see ttccppttaabbllee(5). 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 $$11, $$22 and so on.

TTCCPP-BBAASSEEDD TTAABBLLEESS

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 ttccppttaabbllee(5). This feature is not available in Postfix version 2.1. 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. CCOONNFFIIGGUURRAATTIIOONN PPAARRAAMMEETTEERRSS The following mmaaiinn..ccff parameters are especially relevant. The text below provides only a parameter summary. See postconf(5) for more details including examples. rreellooccaatteeddmmaappss

List of lookup tables for relocated users or sites.

Other parameters of interest: iinneettiinntteerrffaacceess The network interface addresses that this system receives mail on. You need to stop and start Postfix when this parameter changes. mmyyddeessttiinnaattiioonn List of domains that this mail system considers local. mmyyoorriiggiinn

The domain that is appended to locally-posted mail.

pprrooxxyyiinntteerrffaacceess Other interfaces that this machine receives mail on by way of a proxy agent or network address translator.
