I disagree.

Hosting your own email is really easy. I've been doing that for decades and I rarely need maintenance other than regular updates and backups. Minutes a month at most, usually.

That said, setting up your own email hosting is rather involved, although you can limit that to a certain extent with platforms like mail-in-a-box[0] and a raft of others.

If you're comfortable with basic Unix/Linux CLI tools and shells and you are able to follow explicit instructions, it's not too difficult to set up -- but it will take some time as there are a lot of moving parts

You may think I'm splitting hairs. But I don't mean to do so. Once it's set up properly, hosting your own email is incredibly easy.

The "Email Authentication (server-to-server)" section shouldn't be under "extend". In 2025, if you actually want others to receive your email, setting these up is not optional.
