That since the messages can not be checked unless they can be unpacked,
they should really be blocked. If that is unacceptable, then users should
be educated/forced not to use that ridiculous format.
You could also try manually unpacking some of the attachments with the
tnef decoder, to see whether it's working correctly (don't forget that you
need different binaries on different systems), and if so, how much
time + memory + CPU it is likely to take.

Oh, I might also recommend that when a winmail.dat is blocked, a message
explaining why should be returned to the sender. Possibly including a phone
number for them to contact Microsoft and ask what they think they're playing
Given the recent Gartner Group report that recommends businesses dump IIS
because MS are incapable of securing it (see http://www.theregister.co.uk/content/archive/21853.html if it's working), maybe they'll start to take things
like this a little more seriously.
