You don't have aliases for this list (or at least for the posting
address). If you handle list aliases manually, you need to add them.
If you have Mailman/Postfix integration set up so Mailman
automatically maintains aliases for Postfix, run Mailman's
bin/genaliases to resync the aliases with the lists.
