If you're looking to block all files except a limited set of extensions, 
this is probably better done a layer up in your mail flow.  I call Clam 
from MIMEDefang, for instance, so I would configure MIMEDefang to reject 
mail that has any other file types attached.

However, the three you've listed can all contain malware;  you really 
don't want to *skip* scanning those.
