relocated - format of Postfix relocated table
The optional relocated file provides the information that
is used in "user has moved to new_location" bounce mes-
Normally, the file serves as input to the postmap(1) com-
mand. 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
Alternatively, the table can be provided as a regular-
expression map where patterns are given as regular expres-
sions. In that case, the lookups are done in a slightly
different way as described below.
Table lookups are case insensitive.
The format of the table is as follows:
o Blank lines are ignored, as are lines beginning
o An entry has one of the following form:
Where new_location specifies contact information
such as an email address, or perhaps a street
address or telephone number.
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 following:
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
Matches every address in domain. This form has the
When the search fails, and the address localpart contains
the optional recipient delimiter (e.g., user+foo@domain),
the search is repeated for the unextended address (e.g.
This section describes how the table lookups change when
the table is given in the form of regular expressions. For
a description of regular 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
Patterns are applied in the order as specified in the
table, until a pattern is found that matches the search
Results are the same as with normal indexed file lookups,
with the additional feature that parenthesized substrings
from the pattern can be interpolated as $1, $2 and so on.
The table format does not understand quoting conventions.
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 postfixreload
command after a configuration change.
