NAME

relocated - Postfix relocated table format  

SYNOPSIS

postmap /etc/postfix/relocated
 

DESCRIPTION

The optional relocated(5) table provides the information that is used in "user has moved to new_location" bounce messages.

Normally, the relocated(5) 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" 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 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.  

CASE FOLDING


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.
 

TABLE FORMAT


The input format for the postmap(1) command is as follows:
An entry has one of the following form:

     pattern      new_location

Where new_location specifies contact information such as an email address, or perhaps a street address or telephone number.

Empty lines and whitespace-only lines are ignored, as are lines whose first non-whitespace character is a `#'.
A logical line starts with non-whitespace text. A line that starts with whitespace continues a logical line.
 

TABLE SEARCH ORDER


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 $myorigin, when site is listed in $mydestination, or when site is listed in $inet_interfaces or $proxy_interfaces.
@domain
Matches other addresses 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 or when lookups are
directed to a TCP-based server. For a description of regular
expression lookup table syntax, see regexp_table(5) or
pcre_table(5). For a description of the TCP client/server
table lookup protocol, see tcp_table(5).
This feature is not available up to and including Postfix version 2.4.

Each pattern is a regular expression that is applied to the entire address being looked up. Thus, [email protected] 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 interpolated as $1, $2 and so on.  

TCP-BASED TABLES


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 tcp_table(5).
This feature is not available up to and including Postfix version 2.4.

Each lookup operation uses the entire address once. Thus, [email protected] mail addresses are not broken up into their user and @domain constituent 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.  

CONFIGURATION PARAMETERS


The following main.cf parameters are especially relevant.
The text below provides only a parameter summary. See
postconf(5) for more details including examples.
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. You need to stop and start Postfix when this parameter changes.
mydestination
List of domains that this mail system considers local.
myorigin
The domain that is appended to locally-posted mail.
proxy_interfaces
Other interfaces that this machine receives mail on by way of a proxy agent or network address translator.
