This is not a subtle difference. The Return-Path header gets added (or replaced, in the case it is already there) by the receiving MTA with the MAIL FROM address. It is placed there only for convenience of the receiving part. Setting the Return-Path header on outbound messages has no effect. What you need to change is the MAIL FROM address, as already explained a few times in this thread. Cheers, Daniele
