Leaving aside the interpersonal politics here, winmail.dat is unwelcome
because it's proprietary junk attached to messages. From memory, it's
generated by one or more of those MS clients I've never used: outlook,
exchange, ???... sorry, not bashing here, I just don't know which is
which.
There's a command-line decoder at http://sourceforge.net/projects/tnef/
that can be used by either an admin or a user to decode the nasty little
buggers.
