This seems to assume that spam is well formed and valid, which is
usually not the case. As someone else pointed out, you would be more
likely to filter our valid attachments than spam. I haven't tried it,
but looking for <HTML> is probably going to work as well as anything
you have suggested. My suggestion would be that you take a different
approach and use POPFile, SpamAssassin, or something like that.
