This video was recently posted to the MIMEDefang list, and illustrates how
bad the RFC's for mail format are. No wonder SA has such trouble deciding
what's spam and what's legitimate. NOTHING is legitimate, due to problems
with the standards. (And this doesn't even discuss SMTP, just the format of
the message.)
As seen at YAPC::NA::2008, "Email Hates the Living":

It's a good overview of how broken the RFCs are, with an extra helping
of zombie humour on top. Worth a look if you have an hour to spare,
though some of the slides are a bit blurry.
