Why is the out queue backlogged with 120 messages? Why are there 121
messages being retried. What is in Mailman's smtp-failure log?
What does Mailman's smtp log look like? Does it show evidence of

Why so many runners? Do you really need that much parallelism?
The issue appears to be a backlogged 'out' queue. In order to say more,
we need to know what's causing all the retries (smtp-failure log) and
whether there are outgoing messages taking inordinately long to
process (smtp log).
