Kerio adds SpamAssassin to MailServer

April 9, 2003 12:00 PM ET

Macworld - Using the multiplatform e-mail server software MailServer to spam or harvest directories has just gotten tougher, thanks Kerio Technologies Inc.'s recent upgrade to MailServer v5.6.

Spam -- or unsolicted commercial e-mail advertising -- is pandemic across the Internet. One study from Ferris Research notes that the average corporate e-mail user gets three spams per day with the numbers increasing over time. While MailServer already had anti-spam features built in, the new version of Kerio's mail server software gains the open source SpamAssassin, which uses techniques like header analysis, content analysis, blacklist checking and collaborate spam-tracking database checking to flush out perpetrators.

What's more, MailServer has been augmented to help prevent directory harvest attacks -- a special technique used by some spammers to acquire precise lists of valid e-mail addresses by exploiting a shortcoming of the popular SMTP protocol. MailServer monitors unusual changes in SMTP activity and applies defensive techniques to get around the problem, including slow down responses, faking responses and cutting off connections all together.

Kerio MailServer 5.6 runs on OS X, Windows and Red Hat Linux. The new version extends directory service support to Apple OpenDirectory, enabling users to be transparently managed through Mac OS X Server.

Kerio MailServer 5.6 licenses start at $395. The latest version, 5.6.1 is ready for download. This point update from 5.6 fixes bugs and improves features.
