Have you spent any time in these ‘home lab enthusiasts’ spaces? Nobody here is suggesting that you should go and self host email. Nobody is making it sound easy. In fact if you look at posts talking about email, almost every time the subject of email comes up you have a significant portion of the community saying it’s outright not worth self hosting email. It’s such a time consuming and opaque process to figure out why email isn’t being sent or received that few do so.

Do you really think a self hosting community has no idea how difficult and time consuming self hosting email is?
