Commtouch Announces New Messaging Security Milter

Plug-in Enables Superior Spam and Malware Detection for Open Source MTAs
SUNNYVALE, Calif.--(Business Wire)--
Commtouch® (Nasdaq:CTCH) today announced the availability of its new Milter
plug-in, a cross-platform, multi-service Sendmail plug-in designed to enable
straightforward integration of Commtouch messaging security filters with
Sendmail and Postfix mail transfer agents (MTAs). The Commtouch Milter offers
enhanced spam and malware detection based on Commtouch Recurrent Pattern
DetectionTM (RPDTM) and GlobalView technologies.

"The Commtouch Milter is a quick, easy way to integrate Commtouch messaging
protection into these leading open source messaging platforms, and any others
that can work with a Milter, beefing up security and the detection of zombie- or
botnet-generated spam," said Gabriel Mizrahi, Commtouch vice president of
technologies. "Using the Commtouch Milter, the Sendmail or Postfix MTA can block
harmful or unwanted emails from entering an organization`s network at the
network perimeter, saving bandwidth and storage resources."

The Commtouch Milter can be integrated to provide the following advanced
Commtouch messaging security solutions:

* Anti-Spam
* Zero-Hour Virus Outbreak Protection
* GlobalViewTM Mail Reputation Service

As new messages arrive to the MTA, the Commtouch Milter determines whether or
not the messages or the sending IPs pose a security threat, if they are spam or
phishing messages, contain a virus, or were sent from a zombie IP address. The
Commtouch engines query the Commtouch global data centers, which analyze more
than two billion emails per day to provide real-time classifications of the most
recent outbreaks. This allows the Commtouch Milter to block messaging threats
within seconds of their release.

Sendmail and Postfix are two of the most common mail transfer agents in use
today. Security vendors and service providers integrating the Commtouch Milter
into their offerings will be able to improve their competitive offering by
increasing security, saving valuable time and resources, and increasing
productivity with reliance on a fully commercial service.
