We offer one of the best anti-spam
solutions available. This solution was born in the crucible of the
EFF(Electronic Freedom Foundation) and has been refined since 1991.
Here's what some of our customers are saying:
"I usually have 200 emails
sitting in my mailbox, but I only had about 11"
Insurance Company, Skip Jue, Owner
"Now that i think about it ...
there has been nothing. That is good stuff. "
Logiquick, Jahi Toler, Owner
Here are the techniques we use to filter incoming
email:
- Bayesian Logic: Based on stream of what words
are known to exist in Spam and which words are known to exist
in Ham(legitimate emails). This is based on the same technique
that Google uses for processing.
- Header Analysis: Spammers use a number of tricks
to mask their identities, fool you into thinking they've sent
a valid mail, or fool you into thinking you must have subscribed
at some stage. Our solution tries to spot these tricks.
- Whitelisting: A valid list of email addresses
and domains which are allowed to send email to our system.
- Text Analysis: again, spam mails often have
a characteristic style which our system tracks.
- Blacklists: Our solution supports many useful
existing blacklists, such as spamhaus.org. Blacklisting based
on what spam links too. Our blacklist is also based on IP addresses.
We are very careful about being overly aggressive with blacklists,
as often times legitimate domains can be blacklisted by them.
- Razor: Vipul's Razor is a collaborative spam-tracking
database, which works by taking a signature of spam messages.
Since spam typically operates by sending an identical message
to hundreds of people, Razor short-circuits this by allowing the
first person to receive a spam to add it to the database at which
point everyone else will automatically block it.
- Pyzor: An open source in implementation of Vipul's
Razor
Once identified, the mail can then be
optionally tagged as spam for later filtering using the user's own
mail application.
If incoming email receives a high score, it is most likely spam
and will be automatically deleted. The chances of a message not
being spam, but being rated as spam are approximately 1 in 100,000,
so false positives should be minimal.
Spam that falls into the grey area of what is or is not spam, will
be rated as "low spam" and may be filtered by your email
application into an appropriate folder. Spam which receives a "no
spam" score will almost certainly be legitimate email.
