Folks -- quick note from the SpamAssassin side of things -- we found
we had to write our own, alright.  You've gotta be supremely defensive
about how ill-formed the mail could be, plus some of those make great
spam-signs too.  Most "normal" mail pkgs assume some "safe" assumptions
either for efficiency or easy code, but with a spam filter, you're
in unsafe territory anyway ;)
