Computer Mail Services, Inc. Releases Praetor Version 2.1 Providing More Efficient Bayesian Filtering; Improvements Include Cached Bayesian Tokens And Simplified Administration.

SOUTHFIELD, Mich. -- Computer Mail Services, Inc., a leading email security and management software provider, today announced the release of Praetor version 2.1. This email content filter product acts as a comprehensive messaging firewall to protect any SMTP mail server such as Microsoft Exchange, Lotus Domino, Novell GroupWise, and Sendmail.

Version 2.1 implements new features to speed spam detection and improve administration. It also includes a change to the way the product performs DNS Blacklist filtering to reflect new spammers' tactics.

Faster Bayesian Statistical Filtering

Praetor v2.1 now implements a memory cache for the Bayesian token database instead of relying on a SQL Server, an improvement that significantly speeds access and results in nearly doubling the message filtering rate. It also extends to larger sites the usability of the free Microsoft SQL Desktop Engine, saving the cost of buying a SQL Server license.

Improved Administration

Praetor administration simplifies control of its multiple spam detection methods. In its BASIC mode pre-configured rule filters are used. The ADVANCED mode uses rule filters that are fully configurable and are a superset of the default pre-configured rules. Additionally the search tool now includes message field criteria allowing the administrator to quickly locate messages in the event log.

Changing Spammer Tactics

Spammers have changed their practices in response to the overwhelming use of DNS blackhole lists by mail servers to filter spam. One tactic simulates a denial-of-service attack on the mail server. To prevent this attack, Praetor now implements the DNS blackhole list filtering at the message level. This also provides the benefit of capturing more information about the spam messages than just the IP address of the spammers' mail server.

Pricing and Availability

Praetor is priced beginning at $350 for 10 users; as the user count grows, the cost per user becomes more economical due to volume discount pricing.

Supported customers are qualified to receive this version at no additional charge and will be notified via email.
