Book Description
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.

Book Description
After 10 years of development the Dovecot IMAP server is now a benchmark in terms of stability, range of features and performance. Whether you need a single IMAP server for small user groups, a cluster system with high availability for enterprises with several thousand employees, or a complex infrastructure with directors, caching proxies and active/active setups for Internet Service Providers, Dovecot offers concepts and solutions for all kinds of requirements without becoming too complex. Based on extensive experience of many Dovecot projects, this book supports administrators during the conceptual design phase, helps avoid errors and strategically wrong decisions, and shows how to implement different configurations by means of concrete and reproducible instructions.

Book Description
Linux consistently turns up high in the list of popular Internet servers, whether it's for the Web, anonymous FTP, or general services like DNS and routing mail. But security is uppermost on the mind of anyone providing such a service. Any server experiences casual probe attempts dozens of time a day, and serious break-in attempts with some frequency as well. As the cost of broadband and other high-speed Internet connectivity has gone down, and its availability has increased, more Linux users are providing or considering providing Internet services such as HTTP, Anonymous FTP, etc., to the world at large. At the same time, some important, powerful, and popular Open Source tools have emerged and rapidly matured--some of which rival expensive commercial equivalents--making Linux a particularly appropriate platform for providing secure Internet services. Building Secure Servers with Linux will help you master the principles of reliable system and network security by combining practical advice with a firm knowledge of the technical tools needed to ensure security. The book focuses on the most common use of Linux--as a hub offering services to an organization or the larger Internet--and shows readers how to harden their hosts against attacks. Author Mick Bauer, a security consultant, network architect, and lead author of the popular Paranoid Penguin column in Linux Journal, carefully outlines the security risks, defines precautions that can minimize those risks, and offers recipes for robust security. The book does not cover firewalls, but covers the more common situation where an organization protects its hub using other systems as firewalls, often proprietary firewalls. The book includes: Precise directions for securing common services, including the Web, mail, DNS, and file transfer. Ancillary tasks, such as hardening Linux, using SSH and certificates for tunneling, and using iptables for firewalling. Basic installation of intrusion detection tools. Writing for Linux users with little security expertise, the author explains security concepts and techniques in clear language, beginning with the fundamentals. Building Secure Servers with Linux provides a unique balance of "big picture" principles that transcend specific software packages and version numbers, and very clear procedures on securing some of those software packages. An all-inclusive resource for Linux users who wish to harden their systems, the book covers general security as well as key services such as DNS, the Apache Web server, mail, file transfer, and secure shell. With this book in hand, you'll have everything you need to ensure robust security of your Linux system.
