Postfix: The Definitive Guide

Image
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 too

Professional Linux Programming

Image
As Linux continues to grow in popularity, there has never been more of a need to understand how to develop for this platform. Rather than focusing on a particular language or development technique, Professional Linux Programming looks at the different development environments within Linux - the kernel, the desktop, and the web - and then demonstrates best practices, tools, and techniques for integrating applications with the OS as a whole. This book is essential for understanding the nuances that differentiate programming for Linux from programming for any other platform. After beginning with simple shell scripts, the reader quickly moves on to the more advanced topics like software drivers and the graphical interface. The wide variety of tools that you can use to build application software, utilities, and even the Linux kernel itself are covered. You'll also explore the unique components of a Linux system and delve into the inner workings of the system. And you'll find

Sams Teach Yourself Regular Expressions in 10 Minutes (Sams)

Image
RegEx is supported in all major development environments (for use in editing and working with code) and will thus appeal to anyone using these tools. In addition, every JavaScript developer should be using RegEx, but most don't as it has never been taught to them properly before. Developers using ASP, C#, ColdFusion, Java JSP, PHP, Perl, Python, and more can (and should) be using RegEx, and so every one of them is a potential reader too. The reader of this book will learn how to: Match characters sets Match repeating characters (using minimums and maximums if needed) Match (or ignore) based on case Build sub-expressions Use all of the special characters Work with excape sequences Use POSIX classes to simplify complex expressions Use back-references Use look-behind operators Sams Teach Yourself Regular Expressions in 10 Minutes is a tutorial book organized into a series of easy-to-follow 10-minute lessons. These well targeted lessons teach you in 10 minutes wh

Beginning Regular Expressions (Programmer to Programmer) [Wrox]

Image
This book introduces the various parts of the construction of a regular expression pattern, explains what they mean, and walks you through working examples showing how they work and why they do what they do. By working through the examples, you will build your understanding of how to make regular expressions do what you want them to do and avoid creating regular expressions that don’t meet your intentions. Beginning chapters introduce regular expressions and show you a method you can use to break down a text manipulation problem into component parts so that you can make an intelligent choice about constructing a regular expression pattern that matches what you want it to match and avoids matching unwanted text. To solve more complex problems, you should set out a problem definition and progressively refine it to express it in English in a way that corresponds to a regular expression pattern that does what you want it to do. The second part of the book devotes a chapter to ea
