Here is my advice to anyone wanting to test out self-hosting email. Start by using your self-hosted email to sign-up for accounts. You don't have to use the email address for your personal correspondence
Use Mail-in-a-box to get started [1]. You can literally set it up in a couple of hours by following the instructions and everything should just work.
After a few years, you can think about switching your personal correspondence to your new email.
