I am currently evaluating AntiVirus tools for Exchange2000. Does anyone have any opinions on GFI's products that they would like to share?

I have a large and complex environment. There are numerous remote SITES with there own connections. To manage mail flow a little smoother (safer) I configured Mail Security and Essentials on the smaller sites. For the main sites, I did something a little more complex.

If you receive 100,000+ messages a day, I do not recommend using just one GFI server (maybe 5 - 10). If you receive 1,000 messages then 1 will work great.

If you have the option, I recommend putting mail essentials on a seperate (non-exchange) server! This will save you grief in the long run.

I do not agree with DaDougInc [Smile]

Mailsecurity, when installed on the same machine as exchange 2k will use Exchange VSAPI, which is an API introduced by Microsoft to help Virus scanner producers to scan the Information Store in a supported way.

I do agree with the ammounts of messages received per day quoted by DaDougInc though [Wink] It is better to distribute the load over mulitple installations.

I agree with both of you.

Installing MS on a dedicated machine gives you best performance on checking those inbound & outbound messages. It will also virus check messages and strip out viruses BEFORE they hit the organisation

Installing MS on the corporate server - runs in VSAPI mode and therefore as part of the messaging system. Will virus check a mail message or public folder posting whenever it is accessed from the Information Store.

Since you are always playing a game of "Catch-Up" with virus signatures there is a sad inevitability that one day a virus will be allowed inbound but assuming that the VSAPI machine is updating its signatures on a frequent basis it will catch the virus retrospectively.

So, the ideal is to have an MS machine checking messages INBOUND on the DMZ (this machine also running Mail Essentials for Anti-Spam, Auto-Replies and Disclaimers). On the mailbox servers we have VSAPI mode running to check OUTBOUND and INTERNAL.

My clients use MS and are generally happy with it only complaining when they feel that it is too stringent!
