Mail viruses are frequently of almost any MIME type ... it's usually the file extension that determines what certain brain-damaged MUAs pay attention to. Unfortunately the solution I've been using is Exim (www.exim.org) specific ... a carefully crafted filter using regexps to check for certain file extensions in a message whilst ignoring all the MIME encapsulation stuff. It seems to be pretty successful, although it isn't a 100% cure ... I've been using it for a couple of years and no outbreaks of mail viruses where I work. The latest version of the filter is lurking in the Exim mailing list archive, and it might be possible to hack it to work with qmail. I can dig up a copy if anyone is interested in working on it.
