Note that is a pretty poor excuse (the unenforcability part.)  Every mail
client announces what is is every time mail is sent.  Use your favorite
NIDS to RST the connections and/or correlate them to usernames when they
use the same IP to get POP/IMAP mail.

I'm not faulting you... I'm faulting people who assuming something is a
social problem when there's a dandy technical solution.

(Or I just misunderstand the problem... there is a risk just having
Outlook/OE installed, even if you don't use it.  I don't think you can
take it off nowadays without going to a lot of trouble to make a Windows
Lite.)
