NAME

       relocated - format of Postfix relocated table

SYNOPSIS

       postmap /etc/postfix/relocated

DESCRIPTION

       The optional relocated table provides the information that is used in "user has moved to new_location" bounce messages.

       Normally,  the  relocated table is specified as a text file that serves as input to the postmap(1) command.  The result, an indexed file in
       dbm or db format, is used for fast searching by the mail system. Execute the command postmap /etc/postfix/relocated 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. In that case, the
       lookups are done in a slightly different way as described below.

       Table lookups are case insensitive.

TABLE FORMAT

       The format of the table is as follows:

       o      An entry has one of the following form:
		   key	new_location
	      Where new_location 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, the key field is one of  the  follow-
       ing:

       user@domain
	      Matches user@domain. This form has precedence over all other forms.

       user   Matches user@site when site is $myorigin, when site is listed in $mydestination, or when site is listed in $inet_interfaces.

       @domain
	      Matches every address in domain. This form has the lowest precedence.

ADDRESS EXTENSION

       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.

REGULAR EXPRESSION TABLES

       This section describes how the table lookups change when the table is given in the form of regular expressions. For a description of  regu-
       lar expression lookup table syntax, see regexp_table(5) or pcre_table(5).

       Each pattern is a regular expression that is applied to the entire address being looked up. Thus, user@domain mail addresses are not broken
       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 inter-
       polated as $1, $2 and so on.

BUGS

       The table format does not understand quoting conventions.

CONFIGURATION PARAMETERS

       The  following  main.cf	parameters  are especially relevant to this topic. See the Postfix main.cf file for syntax details and for default
       values. Use the postfix reload command after a configuration change.

       relocated_maps
	      List of lookup tables for relocated users or sites.

       Other parameters of interest:

       inet_interfaces
	      The network interface addresses that this system receives mail on.

       mydestination
	      List of domains that this mail system considers local.

       myorigin
	      The domain that is appended to locally-posted mail.
