As to how to proceed, there are a couple of ways. One is to fix import21 so it ignores this issue. I just reported https://gitlab.com/mailman/mailman/issues/618 on this, but I'm not sure how to fix it. I don't think it will work to try the pickle.load and pass the ModuleNotFoundError exception because I think the rest of the pickled data won't be returned.
It looks like you still have the MM 2.1 installation, so you could use either MM 2.1's bin/withlist or bin/config_list to set the list's bounce_info to an empty dictionary. and then use the updated config.pck for the import.
This assumes that bounce_info is the issue. You can verify that there is a non-empty bounce_info dictionary with either bin/withlist or bin/dumpdb.
Indeed, bounce_info is not empty!
I think I need more precise instructions on how to empty bounce_info using config_list, though.
