You can re-run the import with the complete mbox as long as you specify
--since= with a date older than any of the messages in the mbox. Without
that, it won't import anything because the messages will all be 'too old'.
Running with the full mbox will be OK as those messages with Message-ID:
headers will be detected as duplicates and won't be added a second time,
but if the mbox is large, it would be faster to run with just the
messages without Message-ID: headers, but possibly not faster overall
considering the effort to extract those messages.

That's expected. Since even somewhat before Mailman 2.1.5, archive
mboxes have been good. It's normally only those started on Mailman 2.0.x
(or older?) or mboxes imported from elsewhere that have significant issues.
