Perhaps I wasn't clear about my suggested implementation. If you used 
"subject" in addition to "relay_ip","mail_from" and "rcpt_to" you would only 
require a subject match while the timer was running for the first blocked 
email. After the passed_count was 1 or more, you would ignore subject. Again, 
the idea is to let email for long time correspondents go through without 
delay.
