Anti-spam software tested on 313,000 spam mails

VBSpam vigorously tests spam filtration ability with 313,000 spam mails.

Kaspersky Lab, a prominent developer of secure content management solutions, has received a ‘Golden Certificate’ from the authoritative British IT security magazine Virus Bulletin, for its Kaspersky Anti-Spam 3.0  offering. Virus Bulletin certifies products with silver, gold or platinum awards.

Between 7 and 27 August 2009, 12 of the most popular anti-spam products underwent the VBSpam certification tests created by Virus Bulletin. All products were subjected to the same spam filtration tests, on identical hardware set ups running either Windows or Linux server operating systems.

More than 315,000 emails were used, of which 313,000 contained some spam content, including 19,400 emails from Virus Bulletin’s own spam archive, and over 249,000 emails that were received in real time from the spam traps of Project Honey Pot.

All of the anti-spam solutions tested received the same email flow, originating from dedicated, fixed IP addresses. This hinders the detection of spam by way of standard IP filtration technology. In order to resolve this issue, IP addresses and/or senders’ domain names were added to the email headers.

The Golden Certificate is awarded to products that can demonstrate very high levels of spam detection coupled with a low rate of false positives. Kaspersky Anti-Spam 3.0 earned its Golden Certificate by demonstrating a 98.39% level of spam detection with a minimal false positive rate of 0.63 %.

The Kaspersky solution also detected and blocked 99.01% of all real spam emails that originated from the Project Honey Pot spam traps.
