Indeed. Particularly annoying. Aside from the operational problems you listed, there is an architectural problem with ESMTP for message submission: the IETF refused to describe a way to represent envelope extensions in RFC 822 message headers, which means MUAs have to invent their own non-standard ways to represent this information in draft messages and saved copies of sent messages. A sensible design would be like BCC: where the submission process constructs the envelope based on information in the message header and strips any extraneous headers. If you do that then draft and saved messages can use a standard format and you can trivially put the submission process into the IMAP server. http://www.ietf.org/mail-archive/web/apps-discuss/current/msg11566.html Tony. -- f.anthony.n.finch <[email protected]> http://dotat.at/ Trafalgar: Cyclonic 4 in southeast, otherwise northerly 5 to 7, decreasing 4 or 5. Moderate or rough. Fair. Good. _______________________________________________ Imap-protocol mailing list [email protected] http://mailman13.u.washington.edu/mailman/listinfo/imap-protocol
