Then close the door. If the system is a) properly hardened, b) behind
a stateful firewall in the DMZ (i.e. third NIC), c) access to web
pages requires authentication, d) using SSL certificate, e)
controlled access to Exchange server (read: fixed ports), then I
think the level of risk should be in the 'acceptable' realm.

Frank
