I currently have NAV Corporate edition on my Exchange server, but viruses are still getting through. I know that NAV Enterprise has something that is made just for Exchange Servers, as well as SOPHOS, which we are contemplating switching to this year. My question is, because of this is my exchange server currently not being scanned at all? And, if anyone is using any of this additional anti-virus software, what are you using and how does it work? Does it give you more options about scanning e-mails, and if it detects a virus, does it remove the virus and still send the e-mail, or can you setup the software to remove the entire e-mail so that the user never knows that the message was sent? I appreciate any insight anyone might have. Thank you.
