I think this extension is an important thing to have, so I've put together the

Thanks for doing this.
Quick comments:
In the Introduction, I suggest adding:
SMTP servers have always been able to announce a limit, in a
reply, which means that the client first needed to issue a command. The
mechanism specified here avoids the overhead of that interactions, by
announcing limits prior to any substantive interaction.
Also:
The Limits mechanism provides an announcement at the start of a
session. Some servers vary their limits, as a session progresses, based
on their obtaining more information. The Limits mechanism does not
cover in-session limitation changes.
