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.
Filtering Highlights
Thousands of email characteristics ("DNA") are used to identify spam
25 third-party spam databases, several DNS checks, and message-formatting
tests are also used when analyzing each email
DNA and other data are used to perform more than 45 tests on every email
Tests are combined into a weighting system and assigned a value
When the total weight of an email is greater than a certain sensitivity
threshold it will be flagged as spam
Integrates with Return Path and Bonded Sender to minimize false-positives
Administrator and User Controls
Sensitivity can be controlled by administrators and end users
Email users can add senders, domains, and IPs to their safelist to ensure
that email from these senders is never filtered as spam
Email users can add senders, domains, and IPs to their blacklist to ensure
that email from these senders is always filtered as spam
Email users have several options for handling email once it is flagged as
spam
Email users can choose the exclusive setting, which allows them to block
email from senders outside of their safelist
Email administrators can also manage global spam preferences, safelists, and
blacklists at the domain and the user level
Email users and administrators can enable greylisting, which helps reduce
spam by evaluating the authenticity of email from unrecognized senders
