I absolutely do recall Timo discussing implementing it at some point - this way dovecot could actually provide its own submission agent (one reason I'd love to see this would be the ability to DISABLE the 'Save copy to Sent folder' option in mail clients and do that on the server so the message doesn't have to be transferred over the wire twice, which is one thing I *love* about gmail)
that would make dovecot to a MTA, but how do you explain this the MUA aka mail-client? gmail can do it because it is a webinterface not acting with mail-protocols on the user side
with standard protocols this is not the way you can go
even if dovecot would have it's own SMTP implementation no client expects such non-standard things
as other example: dbmail could easily move messages to different folders becasue it only has to update one reference but you can't do it this way with IMAP
