I used to run mail servers for a university and I also suggest that no one should do this. It's hard enough to get right when it's your full time job. No one wants that kind of headache just for an email address. Do what I do and pay for Proton and stick your domain on it.

Okay, you want to have that worry hanging over your head be my guest. Something, someday is going to break. Hope it's not something important that didn't get delivered, cause it'll be your fault.
