I don't see where postfix-to-mailman.py is going to help you. I think
it's making things harder.

Yep. You either need to route mail to lists.altdomain.com that hits the
primary MX server to the lists.altdomain.com box, or you need a
separate MX record to do this. Also, if you are going to use
postfix-to-mailman.py, it has to be on the Mailman box, not the MX box.

These domains should be the ones that are used to access the Mailman
web interface and to send mail to mailman from the outside, as they
are the ones that mailman will use for this purpose in generated URLs
and email addresses.
I.e., if an outside user posts to list at example.com, aet
DEFAULT_EMAIL_HOST = 'example.com'
and if an outside user goes to a list's listinfo page at
DEFAULT_URL_HOST = 'www.example.com'
Of course, these relate to host names, DNS entries, etc., but if the
servers, MTAs, DNS, etc are all set up properly, DEFAULT_URL_HOST and
DEFAULT_EMAIL_HOST can be anything and the only things affected will
be advertised and linked URLs and email addresses and perhaps what
lists appear on listinfo and admin overview pages.
In other words, getting them wrong doesn't have any effect on whether
or not mail gets to Mailman.

Either that or you have to arrange in some other way for mail to the
DEFAULT_EMAIL_HOST domain to get to server.altdomain.com
