My design at my previous job was a GFI MailEssentials/MailSecurity box in the DMZ to act as the email screener server, and an Exchange box on the internal network running Computer Associates eTrust AV for Exchange. GFI Screener would pass clean email to the Exchange box, all outgoing SMTP was also funnelled out through the GFI Screener. Not one single virus made it past this setup in 4 years.

But I would agree that if volume is becoming too much, then whatever product you usse should be placed on its own box in front of the Excahnge. -----Original Message----- From: Bruce Jarrett-Norton [mailto:bjarrett@xxxxxxxxxxxxxx] Sent: Tue 9/14/2004 2:19 PM To: thin@xxxxxxxxxxxxx Cc: Subject: [THIN] Re: OT: Exchange AV scanner of choice
