Postfix is a Mail Transfer Agent (MTA): software that mail servers use to route email. Postfix is highly respected by experts for its secure design and tremendous reliability. And new users like it because it's so simple to configure. In fact, Postfix has been adopted as the default MTA on Mac OS X. It is also compatible with sendmail, so that existing scripts and programs continue to work seamlesslyafter it is installed.Postfix was written by well-known security expert Wietse Venema, who reviewed this book intensively during its entire development. Author Kyle Dent covers a wide range of Postfix tasks, from virtual hosting to controls for unsolicited commercial email.While basic configuration of Postfix is easy, every site has unique needs that call for a certain amount of study. This book, with careful background explanations and generous examples, eases readers from the basic configuration to the full power of Postfix. It discusses the Postfix interfaces to various tools that round out a fully scalable and highly secure email system. These tools include POP, IMAP, LDAP, MySQL, Simple Authentication and Security Layer (SASL), and Transport Layer Security (TLS, an upgrade of SSL). A reference section for Postfix configuration parameters and an installation guide are included.Topics include:
- Basic installation and configuration
- DNS configuration for email
- Working with POP/IMAP servers
- Hosting multiple domains (virtual hosting)
- Mailing lists
- Handling unsolicited email (spam blocking)
- Security through SASL and TLS

I would have liked a little more detail on setting up POP/IMAP with some examples for dovecot, but then again that is not what this book is about.
Why not five start? Well I almost never give anything five stars. This book is maybe 4 1/2 starts though.
You know that an O'Reilly book is at least going to be half-decent, and possibly excellent. In this case Mr. Dent's work has hit the mark spot on, and to my mind earns an excellent rating. Why ? Well, first of all his writing style is clear, concise and easy to read. Secondly he's covered everything you'd want to know about Postfix, rather than an easy feature subset. And third, he's avoided the common pitfall with software guide books where the writer simply presents a jazzed-up version of a reference guide---lists of configuration parameters and their explaination making up the bulk of the book.
Kyle takes the time, and it's much appreciated by the way, to explain how Postfix features work, why they exist (very important), and when they should be used (or not used). I was particularly overjoyed to see that he has covered the configuration of the server to support both SASL and TLS. I'm sure that those chapters will save me _days_ of hair pulling in crypto-hell.
In summary: If you already run Postfix, and you're not Wietse Venema (well, I'm sure he has a complimentary copy already), then RUN out and buy this book. If you don't run Postfix, but were thinking of changing to a better MTA, then consider your options again because now that this book exists, Postfix is a more attractive choice for many admins. Even if you don't ever plan to run Postfix, this book is a pretty good read for those who are just plain interested in e-mail technology.
