One issue to be aware of with Mail Sentinel (not directly related to anti-spam and a/v, but significant) is the behavior of the mail proxy when the mail server is down. The mail proxy bounces mail with a "not a mail server" type message instead of a "not responding" message. As a result, if you have a store-and-forward solution in place the recovery server probably will not queue mail, it will just bounce everything as undeliverable.

Do you have any data? No, I have no statistical data. We did see some false positives and used the whitelisting feature to overcome them. I do still occasionally see spam messages in my inbox. Sorry I can't provide more info, but I again suggest you try it for yourself. > On Wed, 12 Apr 2006, Roger Cornelius wrote: > > > On 04/12/2006 14:42, Cox, Danny H. wrote: > > > I am looking for accurate (positive and/or negative) input on how the > > > AntiSPAM and AntiVirus features (under Mail Sentinel) work on the > > > GB-WARE product.
