One thing that I noticed recently going through mboxutils.py is that
if a message fails to parse for some reason, spambayes then strips off
_ALL_ headers and tries again.  This could obviously be quite damaging...

One mail that I had such troubles with was a MIME-encoded message built
with mime-construct, without any body text before the first MIME section
(the text that usually says "This is a mime-encoded message.  If you're
reading this, please upgrade to a vulnerable mailreader that we can
subvert."... or something along those lines).  Unfortunately, I no
longer have a pristine copy of that mail... spambayes chomped it.  If
it's still an open question when I finish with my graph stuff, then
I may try to regenerate similarly confusing messages...
