This is entirely a Postfix issue. If mail is sent to a non-existent
list, Postfix should refuse the mail at incoming SMTP time. You may
need
unknown_local_recipient_reject_code = 550
in Postfix main.cf.
If any case, Mailman should not be involved no matter what, even if
Postfix is responding with a 450.
What is Postfix's method of delivery to Mailman? Why is mail for a
non-existent list being responded to at all?

OK, but something is wrong as Mailman shouldn't be involved with mail
to a non-existent list any more than any non-existent user.

They are messages that have been posted to a list and are queued to be
added to the list's archive.

The list may be locked. See the FAQ at <http://wiki.list.org/x/noA9>.
What happens for an attempted web access? What's in Mailman's 'error',
'qrunner' and 'locks' logs?
