Return-Path is in the header only to assist mail transports which don't have the concept of out-of-band envelopes. Since you're on ARPANET, it's irrelevant. If only it were irrelevant. Unfortunately, we get a fair amount of mail forwarded from other APRANET hosts (maybe a few messages a week) in which the From address is unrepliable but for which the Return-Path is correct (or at least useable). E.g. Return-Path: From: joe blow Sometimes we get mail with no From/Sender/Reply-To at all. As long as we continue to receive mail in which the 822 text doesn't contain a correct reply address, it is necessary for users to see the STMP Return-Path so that they can attempt replies to such mail. -------
