Been hosting my own email for over 20yrs. Get a vps at some reputable hoster, and make this a dedicated mailserver. Be sure to setup all dns records that are required, and rollout antispam measures.

Thing is, you grew up in the pioneering age of computing, and in that time you needed to do everything yourself. This gave you a bunch of skills for free, that are hard to do today, because most of the hard stuff is automated away and snuck behind a gui and/or containers.
Alma, Talos, OpenBSD
I run unattended-upgrades on all the debian/ubuntu deployments I manage. One of the deployments even has automatic reboots enabled. I still do major upgrades by hand/terraform, but the process itself works flawless in my experience.
OpenLDAP multi-master with a bunch of custom schemas.
Syslog is what you are looking for.
Can you explain what you mean with lightweight?
SCO OpenServer
You expressed yourself just fine and my question is still valid. Do you have the capacity to handle multi Tbit traffic on the edge ips that you use to hide the backend ips? Because if all of those are flooded, not only will the backend app be unreachable, but all your customers will be unreachable as well.
See a search engine and do some research. Maybe try out a bunch of different distros and find out for yourself
We have a bunch of these at the hackerspace. They run vanilla debian and connect to a terminal server using xdmcp. Works like a charm.
