This will work for you.

The only thing I might do different: I've set up a system where the MTA and Mailman are on different VMs, both visible from a large number of "internal" hosts, and the MTA visible from the public Internet. In that case I used SMTP AUTH both incoming and outgoing (paranoia, justified in the case of that client), but in your case with all the relevant nodes running in containers on a single host I don't think that even gives any extra security.

Thank you very much for your assessment 🙂
