Re: [ietf-smtp] Proposal: SMTP Early Pipelining

In article <C8742199DE7666C7C00A3F6C@PSB> you write:
If one wants super-efficient pipelining, one doesn't send EHLO,
one sends a special session-opening command and sends it without
waiting for the 220 greeting message. ...

This sounds ever more like djb's qmtp from 20 years ago, which does
one (1) round trip per message.

(I'm certainly not saying it's perfect, but I've used it and its
junior version QMQP for ages among my internal hosts.)

It seems to me that if both ends have to know in advance that they're
not going to use our mutant SMTP, there's no reason for it to look
like SMTP at all.
