Hexamail Guard offers server-based spam blocking which allows effective server spam filtering. Now the newly released version 2.2 makes the Hexamail solution the most efficient and accurate on the market, by combining neural network techniques to identify and block spam sender addresses with Bayesian pattern matching to identify and block spam content.

Cambridge, UK (PRWEB) July 5, 2004 -- Hexamail Ltd., the leading software company specializing in intelligent email routing, management, auditing and spam blocking, announced today that it has released the latest version of its Hexamail Guard antispam solution with advanced "Neural sender matching".

Hexamail Guard adds to its software an unsurpassed combination of detection algorithms and techniques: Bayesian textual pattern matching on email content, neural based sender address matching, image analysis, attachment blocking, url blocking, popup blocking, script blocking, keyword and expression lists, with automatic Internet updates.

Using a neural network approach, suspicious sender email addresses are identified with a high detection rate and no false positives - this information is combined with results of other tests and measures to raise overall detection rates and reduce false positives. The technique is especially suited to blocking increasingly common small textual spam email with very few other suspicious features.
