Bookreview: The qmail Handbook

Abstract:

"qmail Handbook" is a book written by Dave Sill, the author is well known for the "Life With Qmail". The book was published by Apress. The price is something about 45 Euro, not too expensive and I think it is worthwhile the money.

Introduction

What's qmail ?
What's a MTA ?
What's a MUA ?
qmail was written by Whom ?

Can you answer all the questions above? If you can I believe you are an experienced user (probably an sysadmin or a consultant). If not don't get worry, because this book will explain these things and a lot more.
The book is suitable for both kind of users, the experienced qmail user and the newbie (like me). The book focuses on readers who want to learn how to administrate a qmail system. The author mentions this in the introduction chapter (XXI)
The language used in the book is very accessible, and in my opinion does not confuse the reader with "difficult technical terms", they are well explained and the images support that explanation.
Another good thing, before I forget it: The author does not assume that you have a specific distribution like Slackware or SuSE, but e.g. in the installation he details the differences between different versions of Unix (Linux, FreeBSD).

The book's organization

Here I could detail all the chapters of the book and tell my opinion about them, but I won't do it for two reasons:

My experience can't be compared against the Dave's experience (something like 2 years compared to 15 years).
At the time of writing I could not talk about all the chapters since I haven't read them all. Forgive me for this!

I write about the chapters that I have read and describe them in my own words.

Conclusion

The book is what the title says, "qmail handbook". It really is the handbook of qmail. So if you are an administrator of the mail system and you use qmail then this is for you. No matter if you are an experienced user or not. The book can be on your desk all the time, if any problem occurs, search in the index. It's easy to use. Some blank pages are included for (who knows) any annotation.

Probably the reader, when sending an email to anyone, e.g. a person in Dallas sends an email to his French friend in Paris, may wonder what happens to the email? What route does it take? ...
Well, the book can help you answering these questions, since it gives a technical description of qmail but also, gives theoretical explanations about the processes that qmail handles, and so on...

You can find other peoples opinions if you search for the book at amazon.

The final decision is always up to you...
