Ah. And, not surprisingly, when I tried to solve my problem using an alternative smtp in my master.cf, it did precisely that -- the second smtp threw the message back into the queue, and my one-and-only Postfix dutifully pulled it out of the queue and processed it all over again from scratch, leading to a loop. So I assume there's no way to tag messages in a single Postfix queue with some sort of "already processed once -- let the secondary smtp agent take care of this one" marker? Instead, doing this requires a separate Postfix instance (with its own separate queue)? Rich Wales ri...@richw.org
