***McAfee SpamKiller Makes 'Intelligent' Decisions About Email
With Bayesian Filtering

Santa Clara, California
April 12, 2004

Network Associates, Inc., announced that it has incorporated
Bayesian filtering into the latest McAfee SpamAssassin engine.
With this technology McAfee SpamKiller for Mail Servers and
McAfee SpamKiller appliances will have the ability to make
decisions about the email messages customers receive.

Bayesian auto-learning functionality learns from a company's spam
and non-spam email, improving the detection rates over time. This
enables McAfee SpamKiller to tailor itself to each company's
need, as spam to one company can often be deemed important email
to another. Bayesian filtering also offers increased performance
to McAfee SpamKiller. The McAfee SpamAssassin engine now enables
McAfee SpamKiller to process three to four times more email than
the latest open source version of the McAfee SpamAssassin engine
and adds an additional layer of spam-detection across the whole
McAfee SpamKiller product family.

By utilizing six different methods of detection, McAfee
SpamKiller gives IT administrators a proactive and comprehensive
solution to fighting spam:

Bayesian Filtering -- The McAfee SpamAssassin engine
Bayesian filtering comes pre-configured with an out-of-the
-box filtering database, and features an innovative auto
-learning system which will adapt to the users' particular
email stream

Integrity Analysis -- Examines the header, layout and
organization of every incoming email message and applies
thousands of algorithms to determine if the email is spam

Heuristic Detection -- With a set of automated rules based
on known spam characteristics, McAfee SpamKiller works
proactively to secure the
network against spam

Content Filtering -- The administrator-defined set of words
and phrases helps further identify unwanted email and
inappropriate content

Personalized Black and White Lists -- A set of standards
defined by the administrator and users utilizing white and
black lists to determine both acceptable senders of email,
as well as unwanted and unacceptable senders of email

Self-tuning -- With the ability to learn the characteristics
of email received at the desktop, McAfee SpamKiller powered
by McAfee SpamAssassin is able to adjust the overall spam
score for messages received from known senders. This
functionality is provided in McAfee SpamKiller for Mail
Servers

DNS-Blocklist Support -- The McAfee SpamKiller appliances
are able to integrate with Internet-based DNS blocklists to
ensure that email sent by known "spammers" is automatically
blocked.

McAfee SpamKiller with Bayesian filtering is available
immediately through Network Associates and its channel partners.
