I can't remember the last time I got an actual .com attachment, so I
removed |com| from the $banned_filename_re big extension list, and
added the line
  qr'^\.com$',     # block .com file(1) type
as a safety net.

As an alternative, I suppose you could do something like (untested)
   [ qr'\S@\S+\.com$' => 0 ],
just above the big list.

Or some combination of the above ideas. First match wins.


I expect the newer $banned_namepath_re can do this more elegantly,
but I never bothered to figure out the syntax.
