You could use restriction classes to check if the recipient is restricted, then check if the sender is blacklisted. Unfortunately, this doesn't scale well for different combinations of recipient/sender since you would need a separate class for each recipient. A more flexible choice would be a policy service that can examine both the recipient and sender in one check. http://www.postfix.org/addon.html#policy Either postfwd or apolicy might be worth investigating. -- Noel Jones
