MUA would have to support both of those URLAUTH and BURL extensions, so that it can register a temporary URL on the IMAP server, then connect to SMTP server and give that URL to BURL command (instead of sending the mail with DATA command).
So from MUA's point of view it's basically the same as before: save to IMAP and after that send via SMTP.
This seems like such a convolution...
Given that the RFC already proposes some changes to the IMAP side then it would seem sensible to get the IMAP server to do the proxy connection to the MTA and deliver. Perhaps a simple case of adding a flag when saving into a folder would mark the message as being required to be sent onwards?
Well, I'm not very happy about the idea of IMAP server sending messages to SMTP server either.. :)
