RE: best linux av?
For one, email-borneviruses originating from within your organisation (especially those with recipients within your organisation) will be trapped that way. Don't forget that the first thing some of these pesky viruses do is disable the desktop PC's antivirus software. Perimeter fence security alone is not a sane security policy.

RE: best linux av?
Do you really think that the *ONLY* possible way a virus can get into your Exchange environment is through your SMTP gateway? Let's say a user uses Outlook to POP an email from their personal account into their Exchange mailbox, and that email is infected. Or let's say that a user downloads a file from the Internet that infects their Exchange mailbox. Now what? Since you don't have any mailbox-level virus protection, you have to sit there and watch this thing propagate to all your users and infect all your mailboxes. But at least your gateway will clean it before it sends it out to your customers.

RE: best linux av?
Nope, wrong. Once again you're assuming that all your desktops are happily protected and working fine, in fact that every link in the chain is in place and secure. With viruses you cannot ensure that. You have to attack viruses robustly on ALL fronts, with as few assumptions as possible. The it will be OK because or desktop PCs are protected approach is a recipe for disaster.

Yes, I see your point, although I'd hope my desktop AV would catch this stuff before it reaches the exchange server. What I don't like is the burden of a realtime scan on exchange.

Yes you're right... As an aside, I just turned off the emanager component of Trend and this seems to have helped quite a bit with the CPU load.
