Was self-hosting email for maybe 20 years myself - but I'd say I only really understood enough to make it work. Been using https://mailinabox.email/ for the last 5 years or so and I'm pretty happy with that - works better than what I was doing myself using mostly the same underlying tools.

Yes, Mailinabox works surprisingly well, not to mention that it takes care even of requesting and deploying SSL Certificates.
