Or I bet you could reject certain attachments, like the infamous
Microsoft WINMAIL.DAT file (or something like that; it was just a
"pretty" copy of the plain-text part). Have taboo_body search the
whole message for a body header that the mailers use, like maybe:
/^content-disposition:\s*filename="winmail.dat"\//i
and only bounce those. Or search for "content-transfer-encoding: base64"
to catch MIME attachments that humans can't read. I haven't tested it,
but I think it should work!?
