A fast-paced and easy-to-follow, step-by-step guide that gets you up and running quickly

qmail has quietly become one of the most widely used applications on the Internet today. It's powerful enough to handle mail for systems with millions of users--Like Yahoo! Mail and Hotmail, while remaining compact and manageable enough for the smallest Unix- and Linux-based PC systems. Its component design makes it easy to extend and customize while keeping its key functions secure, so it's no wonder that adoption of qmail continues at a rapid pace.The downside? Apparently none. Except that qmail's unique design can be disorienting to those familiar with other popular MTAs (Mail Transfer Agents). If you're coming from sendmail, for instance, you might have trouble recasting your problems and solutions in qmail terms. qmail first helps you establish a "qmail frame of mind," then explores the installation, configuration, administration, and extension of this powerful MTA. Whether you're installing from scratch or managing mailing lists with thousands of users, qmail provides detailed information about how to make qmail do precisely what you wantqmail concentrates on common tasks like moving a sendmail setup to qmail, or setting up a "POP toaster," a system that provides mail service to a large number of users on other computers sending and retrieving mail remotely. The book also fills crucial gaps in existing documentation, detailing exactly what the core qmail software does.Topics covered include: Installation and configuration, including patching qmail Moving from sendmail to qmail Handling locally and remotely originated messages Managing virtual domains Logging qmail activity Tuning qmail performance Running multiple copies of qmail on the same computer Mailing list setup and management Integrating the qmail MTA with POP and IMAP delivery Filtering out spam and viruses If you need to manage mailing lists, large volumes of mail, or simply find sendmail and other MTAs too complicated, qmail may be exactly what's called for. Our new guide, qmail, will provide the guidance you need to build an email infrastructure that performs well, makes sense, and is easy to maintain.

The qmail Handbook is designed to guide system and mail administrators of all skill levels through the installation, configuration, and maintenance of the qmail server. Author Dave Sill, a longtime qmail user, system administrator, and technical support agent (as well as the author of the popular online tutorial "Life with qmail”), provides you with the practical tools to work with this popular mail server. Sill begins with a discussion of qmails architecture and features, and then delves into a thorough investigation of the installation and configuration processes. You'll learn how to install qmail on several operating systems, and gain valuable insight into proper configuartion, testing procedures, and performance tuning. You'll also learn how to administer users and mail, install filters, and oversee daily qmail operation and maintenance. Throughout, Sill focuses on topics essential to all mail administrators, elaborating on such subjects as configuring mailing list managers, controlling spam, secure networking, scanning for viruses, hosting virtual domains and users, and creating dial-up clients.

Fast, reliable, simple, safe - it's Qmail. Every Internet user knows how important electronic mail is. The role of the administrator is securing the mail server against possible attacks. This micro-course describes the basics of installation, configuration and managing the Qmail electronic mail server. The server was created as a safe alternative to the SMTP Sendmail server. Keywords: qmail, smtp, /var/qmail/alias, alias, /var/qmail/control

This edition offers both new and thoroughly updated hacks for Linux, Windows, OpenBSD, and Mac OS X servers that not only enable readers to secure TCP/IP-based services, but helps them implement a good deal of clever host-based security techniques as well.

You could think of Setting Up LAMP as four books in one, but it's actually something much more valuable: a single volume that presents the open-source technologies known collectively as LAMP—Linux, Apache, MySQL, and PHP—as tightly dovetailed components of today's most affordable and effective platform for building dynamic web-based applications. Each technology has uses outside of this context, of course, but within it they form something greater than the sum of their parts. This book shows you how to take full advantage of this power, walking you through all the steps required to lay your Linux foundation, install and configure your Apache web server, and then begin using PHP to access content stored in MySQL. Here are a few of the specific topics you'll find covered inside: Installing and configuring qmail with support for IMAP, POP3, SMTP, virtual domains, spam filtering, and antivirus Managing system users and groups Configuring your network Creating a custom firewall script using IP tables Recognizing when a system is in distress Handling MySQL database replication Configuring virtual domains Writing a basic PHP script that integrates with MySQL If you're new to all of this, you'll quickly get to where you need to be to start developing and deploying the higher-level pieces of your web application. Even if you have experience with one or all of these technologies, this book—including its quick-start installation appendix—is a resource you'll want close by whenever you're setting up or fine-tuning your LAMP system.
