Running your own mailserver

Email is a basic service we all tend to take for granted. Many big companies provide email as a service, for free, to customers ,and to the general public. Why do they do this?

Personally I'd rather not depend on the (dubious) generosity of Google, Microsoft, Apple, or the like; I'd rather have email that's under my control as far as possible. I can't control what they do with email sent from or to such domains; but I _can_ control where my email is stored, who can access it, and where and when it is sent.

So what does it take to run a mailserver? I'll go into the detail of my own setup (which involves working around my ISP's firewall), explaining the difficulties I keep running into to ensure that email keeps getting to its destination, and that my own family isn't drowned in spam.
