This is designed for bandwidth constrained email clients (think iPhone, hence not too surprising to see this contribution from Apple) where sending the same message twice, once to the SMTP server for submission and another time to the IMAP server to keep a "Sent" copy wastes precious bandwidth (and in some cases money for said bandwidth).

Presumably milter support should be just the same as with ordinary email, so we may need to make "BURL" look like "DATA" to milters. I don't expect that milters should treat the two differently. -- Viktor. P.S.
