Re: [Imap-protocol] Is there some way to detect servers which automatically add sent messages to the Sent mailbox?

I realize its just my young naivete, but the complexity of BURL/URLAUTH
instead of what seems to me the much simpler concept of mail submission via
IMAP just boggles my mind. (if someone has a link to a thread or page that
opines on why, I'd be happy to try to understand, but last year's thread
seemed to come down to "we might not future-proof it against a new
must-have SMTP extension and we would never re-visit the IMAP extension to
also support that")

We don't currently have plans to support BURL.  There'd have to be a pretty
compelling reason, and given that we auto-BCC all msa messages anyways, it
already solves the two copy problem... admittedly, only for clients which
know to configure that way or users that manually configure based on our
support articles.  Also, the user's shouldn't get two copies if our
duplicate detection is working, so it only makes sending slower in that
case.

Frankly, we'd be more likely to support the submission via IMAP draft that
was circulated last year.
