Secure messaging software and appliances vendor Tumbleweed Communications Corp. plans to feed its anti-spam Linux based appliance with a live update service to add another layer of security.
In version 2.2 of the MailGate device, the company has turned on a real-time subscription service that updates the appliance every hour with heuristics on spam, much in the same way as an anti-virus engine works.
It is said to help identify and block spam that has already earlier been analyzed by Tumbleweed staff working at its global message protection lab. These are experts who continually analyze spam to identify new spammer trends and tactics, and create and publish new heuristics to stop them.
Also included along with version 2.2 of MailGate is a web interface that lets users access quarantined messages and filtering options to improve the accuracy of the filterware, using feedback mechanisms that allow them to retrieve false positives from quarantine and to flag false negatives.
