Mailinabox is very much automatic. You run an install script and it asks you for a hostname and domain and thats about it. It also manages updating, backups, certificates all for you. I don't really know how it works but I have been running it for 2 years and it has been fine. The hardest thing was updating to the new ubuntu LTS which involved making sure my backups were safe, wiping the vps and then restoring the backup on a fresh ubuntu install. Because the software is strict on using only a fresh ubuntu install with nothing else on it, it all just works because you have the same config as everyone else.
