It is extremely difficult to self host emails, mainly because most servers will not have you whitelisted, or will blacklist your server as soon as you send something even slightly weird in your headers, which you will do as you learn how to configure whatever thing you find.
You will need to register your domain, acquire a trusted certificate and register dns records with all this information to even hope to have an email be delivered to someone’s inbox if they are not on your server. Lookup SPF on wikipedia.
so unless you want to only send emails to accounts handled by you you will need to publish a lot of information just to be able to communicate with others.
I suggest you pay someone that is not proton if you are not happy with them. You can always layer gpg ontop of any other email account, thunderbird does that by default with two flags.
