I think you should concentrate on the exception route.  Signed messages come
from the client and as such arrive at the server signed.  Any change will
invalidate the signature.

If installed GFI Essentials on the Exchange server & had it only do the
disclaimer, wouldn't it also attach the disclaimer after it was signed?
Or maybe I should ask how I could set up to not send signed mail through
that gateway...

I have plenty of ideas, but you may not like any of them.
 
What needs to happen is that the confidential mails either need to be
excluded from the footer or you will need to add the cert signature after
the disclaimer.  Either way would be different than what you're doing now
and would need a different architecture or a signature mechanism with more
intelligence to realize a message shouldn't be changed if it is signed.

We have Exchange 2000 and use a windows box as our mail gateway for the
outside world.
On the gateway, we use GFI's Security & Essentials programs for screening.
It really works well for us. Also, we Use GFI to attach our standard
disclaimer, and like that as well, BUT.
Now we have to implement certificates on some of our "confidential" mail.
When I send test messages that are signed, the gateway attaches the
disclaimer, and voila, now the massage has been altered. So then end
recipient thinks the mail is bad. Anyone have any ideas? I kind of need both
items (the disclaimer & the certificate...)
