Postfix: The Definitive Guide, 9780596002121 (0596002122), O'Reilly, 2003
Postfix: The Definitive Guide eases readers from the basic configuration to the full power of Postfix. It discusses the 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.

Postfix has an advantage in that it was built with an awareness of the scope and hostile environment it would have to face. In fact, its creation was motivated by the need to overcome some of the problems of software written in a more innocent age. What a difference a little hindsight can make.

I first started using Postfix when I was working with systems in a security-sensitive environment. The promise of more flexibility and better security caught my interest as soon as I heard about it. I was not disappointed. It didn't take long before I was hooked, and preferred using Postfix everywhere. This book is my attempt to create a reference and a guide to understanding how Postfix works. Its main goal is to explain the details and concepts behind Postfix. It also offers instructions for accomplishing many specific tasks.

Documenting a piece of software that is still under active development is a bit like trying to stop running water. Sadly, this book will be incomplete even before it is out. I've tried to structure the information in the book in such a way as to exclude things that might become irrelevant or quickly out-of-date, so that what you find in the book will be good information for a long time to come. However, you may have to supplement this book with online documentation, web sites, and the Postfix mailing list for coverage of the latest features.

Viruses and Nanotechnology (Current Topics in Microbiology and Immunology)
Viral nanoparticles (VNPs) serve as excellent nanobuilding blocks for materials design and fabrication. The main advantages are their nanometer-range size, the propensity to self-assemble into monodisperse nanoparticles of discrete shape and size, the high degree of symmetry and polyvalency, the relative ease of producing large quantities, the...
