DRAC is a daemon that dynamically updates a relay authorization map for
|
2006-11-22 01:23:30 +00:00
|
|
|
Sendmail, Postfix and other MTAs that support it. It provides a way for
|
|
|
|
|
legitimate users to relay mail through an SMTP server, while preventing
|
|
|
|
|
non-authorized users from using it as a spam relay. Authenticated users
|
|
|
|
|
have their IP address added to the map immediately after they have
|
|
|
|
|
authenticated via POP, IMAP, or any other daemon which supports the
|
|
|
|
|
DRAC API. By default, map entries expire after 30 minutes, but can be
|
|
|
|
|
renewed by additional authentication. Periodically checking mail on a
|
|
|
|
|
POP server sufficiently does this. DRAC does not require that the
|
|
|
|
|
POP/IMAP and SMTP server be on the same physical host.
