If the user is sophisticated, forget having even hand screening
work. If hand screening won't work, what will?

On the other hand, if you are paranoid/determined enough, you might just
block whatever you cannot screen.  So, binary attachments are out, just
as uuencoded files etc.  If you're not sure it's safe to go, it does not
go.  Might still not be a 100% safe without hand screening, though.
