I do now have the lmtp runner on port 8024.

In mailman.cfg I set it to listen on the LAN address instead of 172.0.0.1, since I'm expecting mails from my external MTA server.
In the logs of the MTA I see this however: warning: do not list domain fast.za.net in BOTH virtual_mailbox_domains and relay_domains
Mailman creates these entries, but postfix doesn't like it. I don't see any mail delivered to the mailman yet. Is this the problem?
I have come to the conclusion that without substantially hacking power-mail-in-a-box to provide the ability to facility forwarding incoming emails to a list (or other) server, mailman3 cannot be used with it as external MTA.
So I have removed my changes and have done "dpkg-reconfigure postfix" on the mailman3 machine to start with a functional postfix server.
Thanks to all that assisted me in this quest. I may revisit this at some future date, since I think Power-MiaB is a excellent service to use for an internet mail server and provides a whole lot of advantages to a mailing list server, but for now, Postfix properly configured manually will have to do.
