Spam DNA Filtering
We estimate that 85% of all email traffic on the Internet
is spam. Spammers are growing wiser on a daily basis,
learning new methods to manipulate common spam defenses
and obtaining more sophisticated software to trick spam
filters and penetrate email inboxes. In order to win
the war against spam, businesses must evolve their spam
defenses faster than spammers evolve their techniques.
Our Spam DNA Filtering® system accomplishes this
by gathering real-time spam intelligence from a number
of sources and then actively using this intelligence
to block the spam. We track tens of thousands of live
spam email characteristics ("DNA"), which
alone identify the majority of spam. In addition, a
number of third-party spam databases, several DNS checks,
and several message-formatting tests are used when analyzing
each email. We aggregate all of this data into a collection
of several thousand constantly evolving spam tests that
are performed on every email that enters the email hosting
system.
The results of these tests are combined together to
identify more than 98% of spam with virtually zero false-positives.
