--- Comment #5 from Liam Morland <[email protected]> --- (In reply to Jeremy Harris from comment #3) > I think RFC 5322 requires that the From: header contain a non-empty addr-spec > (as opposed to the envelope from, where it can be empty). RFC 3834: Since in most cases it is not appropriate to respond to an automatic response, and the responder is not interested in delivery status messages, a MAIL FROM address of <> MAY be used for this purpose. I agree that it is unusual. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
