I think you misunderstand the fundamental point of SMTP and unreliable
connections.

I don't believe it to be anti-social behaviour, and believe in causing
deliberate command-response penalties based on host-history and current
behaviour. I am quite happy for others to do the same to hosts that I
run.

The point is that the people it seriously impacts are those hosts who are
sending out large amounts of mail to hosts which implement this kind of
policy, not the average mail.

Next you'll be saying that "greylisting" is anti-social, because it forces
the sending MTA to keep a copy on the queue.
