Isn't it sufficient to note SMTP is a single channel client/server state machine protocol? Clients send commands, Servers respond.

I'll quote Section 1.1 as it says it better:

  "SMTP is independent of the particular transmission subsystem and

I see no technical problem on the server side with sending "552 Too much mail data," then a TCP reset. If the client keeps retrying, without fixing the problem, I would block that IP address for a few hours.

The (SMTP client) retry can be from another IP address.
