RE: Vipre for Exchange - Questions
Hmm.. just doing some testing moving messages between mailbox/archives and with either of the vipre scanning engines enabled things are very slow and the CPU on the Exchange box is working very hard. Our Exchange box is a VM on ESX so has a single vCPU - can't see that should be a huge issue given the server is a quad core Xeon that isn't especially busy. I'm toying with whether to move all our a/v scanning to the edge anyway but I would be interested to hear from anyone else if they're seeing anything similar.

We have our Exchange box behind a DMZ relay so anything we accept in Exchange is only checked by Cloudmark. I did find that within 2 minutes of enabling the mail-filters.com engine that one of the discussions on the ntsysadmin list was flagged as spam hence my concern and the question.

I've actually had this disabled for a while now due to the hassles the old Bitdefender engine used to cause (if an update failed Outlook would simply refuse to display messages until you went through a purge routine of the defs on the server). I've just re-enabled it and enabled viper and authentium engines, just after a little reassurance that I'm not making a huge mistake. Thanks!
