Yep, got that. And thanks, I'll add RFC 6409 to the list of RFCs on the wiki. Done. If client do send an auto-response with a NULL return path, do they usually store a copy of that message on the server at all? I would imagine they don't. I also see from the KEYWORDS rfc (5788) that $MDNSent is registered for the MDN purpose. It almost seems that a SENDMDN command is what is indicated for this usage. Again, the "client can't screw it up" philosophy.
