LWN recently reviewed a new self-published book, "run your own
mailserver": <https://lwn.net/Articles/998153/>
The review (worth reading) opens with "The most common piece of advice
given to users who ask about running their own mail server is don't."
I'd pretty much concur with that advice, despite running my own email
servers since the 20th century. I persist partially out of inertia. I
did recently outsource SMTP outbound delivery (only) to Mythic Beasts,
a small UK ISP with a good reputation, and that has proved to be a
success. I may follow up by moving more of the infrastructure over to
them, in time.
With that out of the way, the book looks pretty good.
