[exim-dev] New ratelimit in 4.52

I was hoping to get some clarification on the new rate limiting ACL
condition. While we definitely need rate limiting for accepted
messages, I'd like it to track everything EXCEPT accepted messages.
If a host keeps sending bum messages (whether dropped or denied) I
want to throttle him in the connect ACL as not to waste any more
resources.

A good example are the virus drones. They just keep sending and
sending and sending...each time they get a deny for an unknown user or
a deny from the malware condition. Once they exceed a certain amount
in a certain time, I don't even want them to get the welcome banner.
They get the maximum delay permitted by the RFC and then a 451.

Am I missing something or is this missing the ability to rate limit
based on failure instead of success?
