Defer smtp clients with too many wrong ids

On my postfix 2.4.3 servers I maintain a list of users for most domains
I accept mail for. So I am able to reject SMTP connections to incorrect
ids right after RCPT-TO
I would like to send a TEMPFAIL to all smtp clients who have been
bombarding my servers with undeliverable mails ( atleast attempting to )
in the last half hour
That way I would be rejecting a lot of spams wth TEMPFAIL and by the
time the ip is "released" it would have got listed in rbls
(I believe yahoo does something similar too. )
Is there a postfix implementation for this I could use
Thanks
Ram
