[Mailman-Users] Queue problems

I transferred a lot of list members from a previous list. A dozen of
these has left errors like the following in `logs/smtp-failures`:
delivery to «address» failed with code 450:
4.1.2 «address»: Recipient address rejected:
Domain not found
This is interpreted as a temporary failure so Mailman will put the
letter into `qfiles/retry`. Every 15th minute the retry qrunner will
move all the retry letters back into `qfiles/out`.
My queue had gathered around 70 emails and had 10 recipients or so
with this error, so it took more than half an hour to get through all
of the queue (only to start over).
Since the queue is FIFO _without_ lowering the priority for retries,
it meant that normal subscribers saw a long delay before their letter
was delivered to other list subscribers.
I unsubscribed all addresses that were listed in `logs/smtp-failures`
and then I had to manually delete letters from the qfiles.
But now I see another subscriber has a similar problem and is causing
letters to pile up in qfiles affecting delivery to healthy recipients.
Seems to me that there is a flaw in this system (having retries pile
up and starve regular delivery).
Using Mailman 2.1.9 (Ubuntu installation).
