Topic: Advice on my iRedmail setup

I might be rebuilding my iRedmail setup from scratch. Currently I have it running in an Ubuntu Server VM on my Unraid box. Seems like maybe a dockerized version may be in order. I already have a MariaDB docker and a Swag reverse proxy docker (which I could next get to work with anything iRedmail). I moved to Nextcloud for calendar and contacts (docker works fantastic, auto updates, more actively developed, more features, works with reverse proxy) so I don't need SOGo.

Anyone running iRedmail in a docker and how did you set it up? iRedmail's dockerized version? Rolled your own? Anyone using a reverse proxy with iRedAdmin? What did you have to mess with on iRedmail's nginx config to get it working?
