If it were only that simple...

If your LISTSERV is a backbone server if gets all sorts of things  
sent to it directly from other LISTSERV sites.  These things are  
encoded in ways that anti-virus servers can't handle, or since they  
are coming through LISTSERV rather than via SMTP in some cases, the  
anti-virus servers never even will see them.  I worked at such a site  
and we used to get literally thousands of spamy messages in a week.   
Sometimes thousands in a single DAY.

The good news is LISTSERV does have an exit which allows you to pass  
messages to another program for spam determination.  Not all anti- 
spam engines let you take advantage of this however.
