Prior to Mailman 2.1.26, it processes the queue, sleeps for 15 minutes
and repeats. There has always been a DELIVERY_RETRY_WAIT setting that
defaulted to 1 hour, but prior to 2.1.26, it was ineffective. The
current doc for that setting in Defaults.py is

The way this works is when a delivery fails for a temp failure, the
current time + DELIVERY_RETRY_WAIT is placed in the message's metadata
and the message won't be retried before that time.

If your Mailman is pre 2.1.26, or if DELIVERY_RETRY_WAIT has been set to
a very low value, you can restart RetryRunner by sending it SIGINT. That
should  wake it up to process its queue.
