Sorry, I misread your original message.  Not headers, the body, you're
saying...  Yeah, that'll cause a problem.  Bogofilter doesn't look at
attachment content.  You'll have to create (or find on the internet) a
Spamassassin reverser script that will strip out the MIME stuff and just
leave the original spam portion intact.
