To anyone who uses e-mail, unsolicited or 'Spam' e-mails have
become a regular occurrence. They infuriatingly clutter many
inboxes, just as paper junk mail buried many a front door mat!
As companies have to spend increasing amounts of time having
to sift through their e-mail, we have now introduced a Spam
Filtering service to combat the Spam!
Features
Cybase Spam Filtering functions on 3 separate levels:
Level 1: Spam Assessment
E-mails are scanned against a pre-loaded set of over 926 Spam
characteristics and allocated a score based on the likelihood
of it being Spam. If the email rates more than 5.0 on this grading
scheme, it is flagged up as Spam. Spam Assessment can delete the
offending message before it arrives at the desktop and send a message
to the sender to inform them the message has not been delivered.
Level 2: SpamCop
SpamCop predominately running checks on incoming email against databases
of known spammers. This offers the network manager a very easy to deploy
Anti-Spam measure with proven 99% success rates.
Level 3: Bayesian Filtering
Bayesian filtering is a mathematical approach that adapts over time
and takes the changing strategies of spammers into account. Spam
emails are likely to be made up of similar elements, while valid
emails will have their own determining characteristics. Bayes classifiers
learn as they go, updating both the rules and the scores so that when a
new evasion trick comes along, the message may still have enough other bad
features that the filter will recognize it as spam and if so, the system
will learn the new trick automatically.
Shared Hosting
A slight disadvantage of this system is that the hardware applies a
common set of filtering across all hosted domains, and one client's
spam is another client's marketing campaign! Therefore, a small
proportion of e-mails may not be delivered automatically, and await
a mail administrator to push it out of the quarantine folder.
