Have you actually noticed connections hanging around for that long?
Probably not. But if you're worried about it, increase your qmail-smtpd
concurrency to compensate for a few sessions being tied up by really slow
remote senders.
To reduce the amount of time the bounces stay in the queue, you could
reduce queuelifetime from its default value of a week to three days or
so.
