QMTP doesn't BS: Connect, (send package, wait for reply)*, disconnect.
Package=message,from,to*. Starting with a SMTP handshake would be a lot
of overhead. To be efficient, the sender must (for a session) know that
the recipient does QMTP without connecting via SMTP first. I as just
suggesting that that knowledge come from a previous SMTP session (only
one needed per host) rather than a special MX record.
