This sounds too good to be true, because it kind of is. There is no escaping the cloud (because of email trust) or the requirement of sysadmin’ing this setup (sending/receiving email is critical). If you slack on the details or upkeep, it’s your email.

I have been on an ongoing quest to free myself from cloud services for years now. During this time, I have hosted my personal email (@bloomqu.ist) on a Google Apps G Suite Google Workspace account, which, while convenient, also means that my personal emails are at the whims of one of the world’s most privacy-hostile companies.

Don’t get me wrong – what Zach shared is quite possible, but it’s still too time consuming and difficult to host your own email. It’s untenable long-term. There’s a billion dollar business there waiting for someone to seriously compete with Google on email, and not be evil. Fastmail comes to mind. I could be wrong, but I would characterize them as being an alternative, not seriously competing with Google.
