It would be nice if the server could say "give me a minute to get my stuff together

gets to shed load, the client gets to dump a message out of it's queue and the human
correspondents see fast, in-order mail delivery rather than slow, out-of-order delivery.
That's the end-user visible part of the thought behind
https://datatracker.ietf.org/doc/draft-atkins-smtp-traffic-control/ anyway.
I'd support that proposal. I might even implement it.
Unfortunately, the dominant conversation seems to be around an SMTP
response that only applies to greylisting. I'd never use that or support
it, it's such a teeny-tiny corner case, especially in the B-to-B world
where I live.
