I've been experimenting with the max-failures option on milter-ahead. 
The problem is that too many "benign" mail servers get blocked by this 
option due to out of date mailing list subscriptions and the like.

Is it possible for this to result in a temporary failure (4xx) rather 
than a permanent failure (5xx) so that once the cache expires, these 
"benign" MTAs can try again?

That way I could set the cache-reject-ttl to something relatively short 
(say one hour) and the sending MTA could retry. This may not work if the 
sending MTA retries inside one hour and refreshes the cache - does the 
cache work like that? or are entries expired after the ttl regardless of 
how recently they were used?
