This book is just so-so.

The best book on this subject is "The Book of Postfix: State-of-the-art Message Transport" by Ralf Hildebrandt and Patrick Koetter, from No Starch Press. If you can't get that one, then my second choice would be the O'Reilly book "Postfix: The Definitive Guide" by Kyle Dent.

This one is definitely behind those two. ( )

Switching from Smail to Postfix on my Linux mailserver I just worked through this book: meant for an intermediate to advanced level (book cover) I found this book very well suited for someone of my level of computer knowledge (whis is certainly only just approachiung intermediate). The book is written in an easily understandable prose wchich is fun to read, and tries to cover almost anything necessary to set up an email server with postfix (even some Unix/Linux fundamentals are very well explained - although you should really have some expirience in that area before trying to mess with an email server). Apart from some details like virus scanning which are just shortly touched this is a very complete book - the only "but" being that like all technical books it is and will be aging rapidly as the software develops and additionally turning to online-manuals and software package documentation is a must (but who did not really know that?)
I like this book and my server seems to be working very very well now :) ( )
