[MM3-users] Re: Upgrading dockerized Mailman3 from 0.4 to 0.5.1

@Jeremy, thanks a lot, I followed the procedure, and everything went smoothly. No need for any changes to Mailcow.

@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
