New incoming messages will have the correct data, of course, but imported ones wouldn't, so I'll have to use a more sophisticated approach to handle them, probably by going through mailman's email wrapper, figuring out how to generate a msgdata object for a message, using RFC2369.process and maybe more.

Here's an example script. You need to run this with /opt/mailman/mm/venv/bin/python to get access to the mailman imports.

from mailbox import Maildir, mbox
from mailman.email.message import Message
from mailman.handlers.rfc2369 import process
from mailman.interfaces.listmanager import IListManager
from mailman.utilities.email import add_message_hash
from zope.component import getUtility
mb = mbox('path/to/mbox', factory=Message, create=False)
md = Maildir('path/to/maildir', create=False)
mlist = getUtility(IListManager).get_by_list_id('your.list.id')
for msg in mb:
     add_message_hash(msg)
     process(mlist, msg, {})
     md.add(msg)
mb.close()
md.close()
