I would love to be able to self-host like it was 2025, and with that I mean giving a piece of software the api token to my DNS api, a database, a list of domains and having it figure everything out (certificates, MX records, DKIM etc.) by itself. It should not be impossible.

you can do SmarterMail for 1 domain for free - they are quite good, one of few decent remaining mail systems out there (of course it's commercial for business use)
