Also, postfix*must* know the valid recipients. If you simply accept all mail and let Exchange bounce the undeliverables, it won't take long for your server to be blacklisted as a backscatter source. Either periodically export a list of recipients from Exchange to postfix, or configure LDAP on the postfix server to query your AD. See google for details.
