I didn't see your earlier query but I'll try to answer this one.

One of the ways to this is to install MailScanner from
http://www.mailscanner.info.  When properly installed, this separates
your mail on your existing server into multiple queues - for example, I
have a mail queue that receives the incoming mail, lets MailScanner scan
it, and then it moves the mail to an outgoing queue for more processing.  

MailScanner is fairly powerful and supports multiple virus scanning
engines.  There is detailed documentation on their web site.  You can
do spam filtering too if you want.
