Mailcow is pretty good actually. Setup on a virtual hetzner server took me half an hour, as it is a pretty simple docker container. What took a little longer was migrating my mails over, and setting all the needed DNS records (SPF and the likes). I had a small blacklisting issue in the beginning that could be resolved within 24 hours, since then it works flawlessly.
