That was as far as I got. I diligently stopped right there wanting to get that right before proceding to take my working mail down <smile>. Someone else also pointed out my misunderstanding as you described above. I swapped rcmd to smtp and all was well. I was following the Book of Postfix examples literally, but I didn't see anything to make me think to do otherwise. With the help I got from the other person and now you, too, I was able to get it going. So I have that part behind me and working. Thanks again for the help. Best, Scott
