The optional relocated file provides the information that is used in "user
has moved to new_location" bounce messages.
Table lookups are case insensitive.
The "Maps to..." field specifies contact information such as an email
address, or perhaps a street address or telephone number. It's one of the
following:
- 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 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. user@domain).
