That mailserver, be it running sendmail, has a yummy
configuration file called /etc/mail/virtusertable.
don't forget to makemap hash virtusertable.db < virtusertable;
a restart of the daemon is not required.
virtusertable A domain-specific form of aliasing, allowing multiple
virtual domains to be hosted on one machine. For example,
if the virtuser table contained:
info@foo.com foo-info
info@bar.com bar-info
joe@bar.com error:nouser No such user here
jax@bar.com error:D.S.N:unavailable Address invalid
@baz.org jane@example.net
then mail addressed to info@foo.com will be sent to the
address foo-info, mail addressed to info@bar.com will be
delivered to bar-info, and mail addressed to anyone at baz.org
will be sent to jane@example.net, mail to joe@bar.com will
be rejected with the specified error message, and mail to
jax@bar.com will also have a RFC 1893 compliant error code
D.S.N.
The username from the original address is passed
as %1 allowing:
@foo.org %1@example.com
meaning someone@foo.org will be sent to someone@example.com.
Additionally, if the local part consists of "user+detail"
then "detail" is passed as %2 when a match against user+*
is attempted, so entries like
old+*@foo.org new+%2@example.com
gen+*@foo.org %2@example.com
+*@foo.org %1+%2@example.com
and other forms are possible. Note: to preserve "+detail"
for a default case (@domain) +*@domain must be used as
exemplified above.
All the host names on the left hand side (foo.com, bar.com,
and baz.org) must be in class {w} or class {VirtHost}, the
latter can be defined by the macros VIRTUSER_DOMAIN or
VIRTUSER_DOMAIN_FILE (analogously to MASQUERADE_DOMAIN and
MASQUERADE_DOMAIN_FILE, see below). If VIRTUSER_DOMAIN or
VIRTUSER_DOMAIN_FILE is used, then the entries of class
{VirtHost} are added to class {R}, i.e., relaying is allowed
to (and from) those domains. The default map definition is:
hash /etc/mail/virtusertable
A new definition can be specified as the second argument of
the FEATURE macro, such as
FEATURE(`virtusertable', `dbm /etc/mail/virtusers')
