I believe that those solutions would work with clamAV. One thing I forgot
to mention but that is free and very effective is to use mime_check to
reject any attachment with an executeable extension on Windows (if you can
do that with your recipients). That blocks about 99.99% of everything for
us. We also have an <iframe> exploit check in body_checks that catches
the rest of the Klez cruft. Our virus scanner is just loafing around
these days.
