This book refers to Exim 3.x, which you really should not be using now. Exim 4.x has been out for several years, and configuration is quite different - even conceptually. Don't buy this book, buy the second edition of "The Exim SMTP Mail Server: Official Guide for Release 4", by the same author.
I'm reluctant to give this book such a low score, because it really was an excellent book when it was current.

This book shows just about every configuration one might wish to use when setting up Exim, and it proved very easy to find a configuration that pretty much matched my needs.
What this book lacks is a reference section, so it was not that easy to fine tune the configuration - there was a lot of going backwards and forwards to try and locate where in the book a particular feature had been discussed. Everything is there, and nothing was left out, but finding where it was may at times be a problem.

Exim is a very flexible messaging server for unix/like platforms.
The book is a comfortable reading, and an essential guide/reference to anybody looking at setting up exim. Together with a printout of exim's FAQs I got a system to handle mail for a number of domains with some fancy forwardings and configurations in no time at all (after giving up on configuring sendmail).
