Virus protection

Insure that you have updated .dat files for virus protection.
Distribute a general warning to all users warning them of suspicious emails that they are not familiar with to scan or report before opening.
You can try filtering email messages.

I'm running Norton Anti-virus on my exchange server. It scans incomming email for viruses, and automatically gets updates from Symantec. It may not be the best, but it works fairly well, and doesn't take much of my time. The only problem is when a new virus breaks out and hits us in the first few hours before a virus defination file can be downloaded. That happened once, but I could contain it before it got too far.
Good luck.

Use Network Associates Active Virus Defence, it includes Dr Solomons VScan and Netshield McAfee Groupshield & Webshield plus there is a tool called Outbreak Manager which you can configure to shut down a mail server on suspicious activity, so if thescanner misses something through being too new. Then the spread can be limited very quickly with little or no admin response in the short term, Which is vital in the 24/7 job that I.T. has become (it's always 9 to 5 somewhere in the world).
Also isit vital to keep up with updates to the DAT files and the scan engines.
I have an update routine for servers and clients too long to post here but will gladly e-mail to you.
