Generally (and so far as I know) you have to put Spam-Filtering in front of Exchange. For two clients, I do this via Exchange outsourcing and the outsource company provides spam filtering and a quarantine area for users to review emails that should have been whitelisted. For another client, I installed (on a separate server) Symantec Mail for SMTP V5 with the Premium Anti Spam addition. This application does a very good job of checking and turfing spam and emails laden with viruses. Mail for SMTP offers a quarantine area as well.

I don't think Exchange will do what you want without additional software. ... T
BTW, try writing in lower case with proper capitaliztion.

Sorry about the all caps.  I do have Symantec Information Foundation Mail Security for Microsoft Exchange version 6.0.6.235.    My virus definitions are up to date as of 11/7/08.  I have my computers scan every Friday, it just seems that I have 2 desktops that seem to get a lot of SPAM email and others do not.  Should I scan that desktop by itself?  I should have explained better in my question.

Scanning for viruses and scanning for spam are very different. GIF Image spam, for example, will not be detected as a virus (as it is not), and is difficult to stop except with really good spam filtering software. I know about Mail for SMTP but not about Mail Security for Exchange. I had to do quite a bit of work in terms of policies, blacklisting and whitelisting to get Mail for SMTP to filter everything out.

Have you asked Symantec Support about the type of spam you are getting and how you might stop it with Mail Security for Exchange.

The other thing to consider is to have inbound mail coming to a server which has a firewall between it and Exchange in order to protect the Exchange server. .... T
