Product Description
SpamViper combines dozens of different anti
spam filters with an intuitive yet powerful interface to allow the subscriber
to use webmail or just control the spam
settings and deal with messages in quarantine. The subscriber has both
webmail and industry standard POP3 access to
their email.
SpamViper filtering consists of:
Multi
Level virus scanning. The email is broken apart into a separate file for each
attachment and message body part, then each part is
scanned by our state of the art virus software. The virus databases are updated
every 20 minutes so new viruses are caught before they can spread.
The
Distributed CheckSum System. This system tracks how
many copies of similar emails have been received by other mail servers in the
DCC network. The more copies have been seen in the last 24 hours, the more likely
it is to be spam. We add more than 20 Million spam
signatures to our database each day!
Heuristic rules examining
email subject and body for literally thousands of key phrases and layouts. These
systems use Bayesian rule sets to learn from feedback from all of our subscribers.
If a spam slips through and the subscriber forwards
it to the “SPAM@YOURDOMAIN” address the system learns – if a message is marked
as spam, but is not and the subscriber forwards it
to the NOTSPAM@YOURDOMAIN address the system learns.
Open relay Block lists.
These internet databases track the IP addresses of mail servers known to be wide
open to spammers.
Known Spammer
databases.
An email signature database. Once a given email
has been positively identified as spam a digital “fingerprint”
is taken of the email and entered in a database. Every new email is checked against
this database – if the fingerprint matches there is 100% surety that the email
is spam. In order to eliminate “false positives” a
team of five full time (and very stressed) employees
reviews every new mail fingerprint before it is entered in the database.
These systems run on multiple load balanced clusters of servers. We frequently
see as many as 20,000 inbound messages per
minute to our filtering clusters with no degradation of service. Servers
are added to clusters as needed to always stay ahead of the growth curve.
