Short answer: Don’t.
Long answer: It is a massive amount of work, not just to setup, but also to maintain. On top of the fact that the big email providers block smaller email servers like crazy. Even if you had business class Internet service at home, the IP range is most likely already in their block lists. And if you have it on a VPS, the amount of time and effort it takes to get the security and filtering going properly is nightmarish.
It really sucks, but it’s a fait accompli.
Even if you set up everything perfectly you encounter email providers that only have allow lists and you have to jump through hoops to be allowed to send emails to them (like publishing your whole name and address). I loved the fact that I had a mail server but in the end it didn’t make sense.
