Abstract

Setting the record straight.

As a result of human error (and a reviewer in need of a holiday), a number of mistakes regrettably crept into last month’s VBSpam comparative review. An incorrect formula was used to calculate products’ final scores, making the majority of scores slightly higher than they should have been. With the correct calculations the pass/fail results remain unchanged, although the order of FortiMail and SpamTitan are reversed in the listings of products by final score, with FortiMail now achieving the third highest final score, and SpamTitan coming in fourth.

In addition, it was reported in the July review that in the May review, OnlyMyEmail’s MX-Defender had missed four spam messages. In fact, the product missed only two spam messages on both occasions. VB apologises for the errors and any inconvenience they may have caused. The correct results are all now available at http://www.virusbtn.com/vbspam/archive/test?id=164 and in the updated PDF at http://www.virusbtn.com/pdf/magazine/2011/201107-vbspam-comparative.pdf.
