There is a way around it!
I have had two issues with the the maxking docker image. One is that the regexp is not working properly. I reported that, and it has been fixed in newer code. My other problem is that the docker image creates a user, mailman, that receives uid 103. Well, uid 103 on my system is already taken by systemd-bus-proxy (grep 103 /etc/passwd returns "systemd-bus-proxy:x:103:105:systemd Bus Proxy,,,:/run/systemd:/bin/false").
My solution includes downloading the corrected postfix.py, and replacing the Dockerfile. I put the postfix.py in <docker-mailman>/core/assets/.
My Dockerfile: FROM maxking/mailman-core
RUN grep mailman /etc/passwd && grep mailman /etc/group
&& deluser mailman
&& addgroup -S -g900 mailman
&& adduser -S -u900 mailman mailman
&& grep mailman /etc/passwd && grep mailman /etc/group
COPY assets/postfix.py
/usr/local/lib/python3.6/site-packages/mailman/mta/postfix.py
I then run docker build (with -t parameter, you must look up that yourself). I use a different name for my images, so I end up with (note, there are two tags per image): root@mailer:/home/mailman/docker/docker-mailman_mods/core# docker images REPOSITORY TAG IMAGE ID CREATED SIZE local/mailman_core_900 20171110_2 9649e84767e1 2 days ago 176MB local/mailman_core_900 latest 9649e84767e1 2 days ago 176MB local/mailman_web_900 20171110_2 07a9b3d7ddd6 2 days ago 247MB local/mailman_web_900 latest 07a9b3d7ddd6 2 days ago 247MB
I do the same with the web image, as I need to change the user there, too.
Then, in docker-compose.yaml, I change the line(s) referring to the image name(s):
services: mailman-core: image: local/mailman_core_900 container_name: mailman-core hostname: mailman-core
mailman-web: image: local/mailman_web_900 container_name: mailman-web hostname: mailman-web
I don't know if this is a good solution, but at least it fixes some serious issues with the 3.1's postfix integration that wouldn't otherwise be fixed until the 3.2 release. The bottom line is that it works for me, but it adds an additional layer of complication.

That was it. Perfect. I manually modified my regexp map and it works now. Excellent and Thank you. You're the man. Does mm3 ever refresh those maps or only as I add new domains / lists?
Only when you make changes to domains or lists.

Mark,
I've noticed that even simply restarting the mm3 components those alias maps get rewritten and the problem returns until I can manually edit it.
Yeah, that is true. Transport maps are re-generated everytime the container restarts.
I don't think think there is any way around this right now :(
