I assume you are just a user of a list at ibiblio.org? If so, you can’t fix it. Ibiblio.org has Mailman installed incorrectly. They need to install it correctly. This problem affects all lists managed by this Mailman installation so I assume you have also not been receiving any postings from this list.
