@Stephen, thanks for your reply. The version numbers "0.4" and "0.5.1" do refer to dockerized versions of mailman as described here: https://github.com/maxking/docker-mailman
OK, so when you wrote "combination with Mailcow", you mean that you installed docker-mailman and Mailcow separately, and they are not integrated (except via SMTP/LMTP)? I ask because Mailcow gets mentioned occasionally, and I was under the impression that this was a single install of Mailcow including Mailman (perhaps with Mailman as an optional component).
Again, for docker-mailman questions I suggest that you write the list (both for quicker response, eg, Jeremy, and as a service to other users who may have related questions) and CC Abhilash. As far as I know he's active in development and willing to answer questions. He has stepped back from activity on the list, however.
