I've been talking with the people at malware who posted the initial
advisory about this. It seems that no MIME content is needed at all,
not even badly formatted MIME, just a very long subject line.

I don't have ready access to an Outlook client, so a proper fix for
this will have to wait, but it looks like the suggestion to include
the Subject: header in attachment filename checking is going to be the
most correct response.

A simpler response might be to limit the length of the Subject line to
a sane length, but then we get into the difficult area of defining
"what is sane"?

  The question of whether people should be allowed to harm themselves
  is simple. They *must*.
