2% is a lot of spam these days. With a recent spike that lasted for most of a week we saw ~95% of all incoming mail to our mail servers be spam. If our filtering had only been as good as 2% then the result to the customer would have been about 30% of received email being spam....totally unacceptable. With Declude/Message Sniffer we're currently hovering around 5% of received email (to user mailboxes) being spam (~1 message in 20)....a 6x better filtering than the 2% slipping through you mention with Barracuda.

(little = 2%) Although, they would be happy to sell me a second box in reverse mode for double my price. I went ahead and order the eval unit, we'll see how it goes. But I think you guys are right that I'm leaving a hole here. ~Brad To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
