Kerio MailServer 6.1

Kerio today announced , which adds Sender Policy Framework (SPF), Spam Repellent and dual anti-virus scanning to its existing spam-fighting tools. Designed primarily for small and medium-sized businesses, Kerio MailServer simplifies email, contact and group calendar management to provide improved collaboration for all types of organizations. Kerio says that version 6.1 features significantly improved underlying email security technology with the addition of SPF, a popular method of email domain authentication. This augments the already included Caller ID, a similar technology developed by Microsoft. The company also said that the new Spam Repellent feature "effectively fights off both spam and viruses by inserting a delay in the SMTP handshake, which causes a virus or spam-sending zombie to give up the connection attempt."

"Our tests showed that Spam Repellent effectively cuts 60 to 70% of spam and viruses before they reach the mail server," said Dusan Vitek, VP Marketing at Kerio Technologies Inc. "Best of all, there are no false positives because this technique does not affect legitimate email traffic."

Kerio has also added dual anti-virus scanning so that mail administrators can use both the built-in McAfee Anti-virus and a third party anti-virus through a provided plug-in. The company says that plug-ins are available for Symantec, Sophos, Grisoft AVG, Eset NOD 32, Computer Associates and for the newly added VisNetic Antivirus.

"Harmful content in email is a problem that affects all size organizations," said Dusan Vitek. "The smaller guys don't have the same resources that enterprises do for fighting it. Even the smallest businesses and schools deserve virus and spam-free email and collaboration to help them communicate more efficiently."

Kerio MailServer is available now with pricing starting at $500 for 20 users. It runs on Linux, Mac OS X, and Windows.
