i won't glock up this already busy list with a full copy of the proposal, but before y'all go off and invent something, here's some prior art that's been resoundingly pooh-pooh'd by the smtp community.

Yeah, the problem is that this breaks mailing lists, just like other proposals. Otherwise, it would seem to be a nice concept.
How does it break mailing-lists? If the list sets the envelope sender to <list-request@listserv.domain.com> creating a MAIL-FROM shouldn't be a problem. The only problem I can see is what to do about bounces (i.e. with a null envelope sender) - guess you could use header From instead maybe. Martin

You may be surprised to discover this, but most mailing lists are not proper mailing lists and are not managed with proper mailing list management software. Most mailing lists are actually handled as aliases, and therefore do not modify the envelope sender address.
