SpamTitan, the market leader for virtual email appliances have just announced the latest release, Version 4.04, to combat the increased activity in image based spam.

This recent initiative from spammers to try and subvert traditional anti spam techniques uses a graphical image to carry the spammer's message. Text is imbedded in an image and frequently appears to the user as a normal text email. Traditional spam checkers see this as an image and have little or no content for analyses to define it as spam or genuine email. This category of spam email has increased to significant proportions and has been reported to account for upwards of 25% of current spam.

SpamTitan's use of Optical Character Recognition (OCR) technology allows the anti spam diagnostic engine to analyse and identify text within these images. This text is then compiled and used in conjunction with the existing anti spam rule set to determine if that email is spam or not. These techniques ensure SpamTitan maintains its 99% spam detection rates in protecting mail servers from the constantly growing volumes of spam being sent today.

SpamTitan's OCR technology is available now on SpamTitan for VMware© and SpamTitan ISO, each offering spam detection , dual anti virus engine including Kaspersky Labs and end user quarantine facilities. Both of which are free to download from the SpamTitan website http://www.spamtitan.com
