You can use a restriction class to allow this sender/recipient combination. Some examples are in: http://www.postfix.org/RESTRICTION_CLASS_README.html The limitation with the restriction class feature is it doesn't scale well to lots of restrictions. Each combination needs its own class, so it can quickly become unmanageable. This won't be a problem with bypassing for one recipient. For more flexible multiple combinations, use a milter or policy service. -- Noel Jones
