The *simple* solution is to use SA to block the virus by filtering for the
body content. There seem to be about a half dozen variants on the body of
the email, but you can use a couple of regex to trap them and bump the score
up. The only problem is if you are whitelisting certain domains.. Not much
you can do about that one.. However, if you do not have some of the aliases
that it uses simply drop them at the MTA before the AV kicks in, it should
save you a lot of processing overheads.
