Exim, The Mail Transfer Agent

I was kinda curious what all these configuration options on the mailer agent on my Linux box were for. That mailer agent is Exim, and Philip Hazel, it’s author, happened to just have written a book about it.

The books offers a brief, but complete introduction of how Internet e-mail works.

Exim works like a true Unix toolkit that can be configured in many ways by its system administrator. This books describes all features in complete detail. It does that without turning into the boring books that most references are.

If I were to be the administrator for a corporate mailhub, I would rather have a copy of this book and an Exim installation than Exchange or Sendmail.
