DRAC is a daemon that dynamically updates a relay authorization map for
|
|
Sendmail, Postfix and other MTA's that supports it. It provides a way to allow
|
|
legitimate users to relay mail through an SMTP server, while still preventing
|
|
others from using it as a spam relay. User's IP addresses are added to the map
|
|
immediately after they have authenticated to the POP or IMAP server. By
|
|
default, map entries expire after 30 minutes, but can be renewed by additional
|
|
authentication. Periodically checking mail on a POP server is sufficient to do
|
|
this. The POP and SMTP servers can be on different hosts.
