Commtouch Enhances Apache SpamAssassin Spam and Malware Detection with New Plug-In.

SUNNYVALE, Calif. -- Commtouch[R] (Nasdaq:CTCH) today announced the availability of its new plug-in for Apache SpamAssassin[TM], which offers enhanced spam and malware detection based on Commtouch Recurrent Pattern Detection technology.

"The Commtouch Plug-In is a quick, easy way to inoculate SpamAssassin-protected mail servers against zero-hour threats, and to beef up detection against zombie- or botnet-generated spam," said Amir Lev, Commtouch chief technology officer. "Spam has reached new heights over the past several quarters, and new types of malicious code and blended threats are constantly being introduced by email. Only an automated real-time solution like Commtouch's can defend against these nimble threats."

Commtouch RPD technology is a service "in the cloud" that works by analyzing massive volumes of Internet traffic in real-time to identify recurring malware and spam patterns. The Commtouch plug-in retrieves relevant spam and malware classifications from the Commtouch Detection Centers in real-time. As a result the plug-in provides superior detection against new outbreaks, often hours, or even days, before most other solutions.

Internet Service Providers, software and hardware vendors and very large enterprises can benefit from the Commtouch plug-in, incorporated as an add-on to their SpamAssassin implementations.

SpamAssassin is one of the most widespread open source anti-spam technologies. It works by checking email messages against a series of rules that an administrator updates regularly.
