Anti Spam Features
WHITE LISTS
MailScan for Linux (CommuniGate Pro) allows you to create
a White List of clean domains and users. In addition there is
a list of 'Spam phrases'. Mails with such phrases should be
blocked. The software allows you to apply a severity level to
the phrases from low to high. This allows you to control how
Spam is identified.

RBL AND DUL CONTROLS
MailScan for Linux (CommuniGate Pro) has a list of RBL and DUL
to verify a users authenticity.
MAPS (Mail Abuse Prevention System) provides a list of IP
addresses that are known Spammers or allow spamming. This
list is called as Black hole list. When your server, receives
a mail from a domain, not on its allow domain list, you can
send a query to MAPS Server which verifies the IP.
Spammers sometimes use stealth mail tactics when their initial
Spam attempts are blocked. They use a Dial-Up-Service (DUL)
provider to connect their Spam mail service, to the server.
This is trespassing on your MailServer and the MAPS DUL project
helps in identifying and stopping Spam. The project has a
list of DUL users who are known Spammers. To verify if the
request for connection to your Server is genuine, you can
send a query to dialups.mail-abuse.org. The request is verified
and returned.
