[ILUG] Mime type filerting

I'm running postfix on a gateway... but people are saying to us that the
exchange clients are vulnerable to various 'presumably automatically'
executed mime types... which is true, but unless we move away from exchange
'which I have been arguing for for about 8 months now' we will always have
this type of problem.

But a guy from a security company is trying to pitch a seperate server as a
mime type filterer...
My question is, shouldn't it be possible to filter out mime types on postfix
on my gateway 'before' it gets forwarded to the exchange server ... perhaps
something like
http://pagesperso.erasme.org/michel/piktpages/setups/postfix.php3 .

Someone must have done this kind of thing already... so what is the general
wisdom on such things?
