Regardless of how you state the problem, it should already be clear that postfix does not have native capability to do selective BCC based on the subject. Adding such a feature to the postfix core would require non-trivial redesign and won't happen anytime soon. You might be able to find a milter that can do this; I haven't looked. You might be able to modify an existing proxy, such as amavisd-new, to do this; that will take some work and an unknown amount of time. Your only sure bet is to have postfix BCC everything and use a sieve script after delivery to discard the unwanted messages. [thinking out loud -- amavisd-new has some archiving features built-in. Maybe it can be convinced to trigger on the Subject. Probably worth looking into.] -- Noel Jones
