postmap /etc/postfix/relocated

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.  

*

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.

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.

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 interpolated as $1, $2 and so on.  

Each lookup operation uses the entire address once. 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.

Results are the same as with indexed file lookups.  

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.
