GFI Intros Server-Based Anti-Spam Tool

London-based GFI released a version of its server-based anti-spam tool that allows network users to blacklist or "whitelist" senders via public folders, and enables administrators to tune the Bayesian filter more easily. The new version also includes mail archiving to SQL Server, which permits companies to comply with government regulations more easily.

GFI MailEssentials for Exchange/SMTP 10 also functions as a list server, simplifying the maintenance and distribution of company news. The earlier version of GFI MailEssentials included an automatic "whitelist" management tool automatically adds mail recipients to a user's whitelist and reduce false positives. In the newest version, whitelists can also be built based on domain names, email addresses and keywords.

In the new version, network administrators also can tune the product's Bayesian engine by dragging and dropping spam or "ham" to appropriate public folders. The tool learns from the spam and ham that it collects from folders, improving its spam-detection rate.
