There are times, where the sending MTAs queue size is far to big for the MTA to meet the queue times. I saw such problems multiple times. When graylisting is configured for too short acceptance time, you will have messages, which won't be transmitted.

This is the default for the milter-greylist-port in FreeBSD. Maybe on very heavy loaded servers You have to go back. But even 12hrs should be big enough for very big queues. I think this is your idea of "short acceptance time"? Or are there other parameters I am missing?
For me, the main factor is the greylist time. There is defined, how long NOT to recieve a mail for a touple.
# How long a client has to wait before we accept # the messages it retries to send. Here, 1 hour. # May be overridden by the "-w greylist_delay" command line argument. greylist 5m
but normally this is not the problem... (There are still problems with greylist... but there are greater problems without ;-)
