I assume that the auto-discard policy is mentioned in the list
information, but if not, you should consider adding it.

Yup.  I believe there's an option for those to be batched once a day.

The only thing I could imagine that might be better would be to
integrate this with DMARC reporting, but Mailman 2 doesn't provide a
querying facility, so that's quite hard to do.  Mailman 3 does allow
querying through the REST API, so it should be fairly
straightforward.  Note to self: Maybe an idea for next year's GSoC.
