内容説明
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 want qmail 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.

Authoritative and complete - everything you need for qmail
2004/6/17
形式:ペーパーバック
Although sendmail is installed in more Internet mail servers than any other Mail Transfer Agent (MTA) it has come under scrutiny for being a large awkward program by today's standards. More and more new MTA servers are moving to a modular program like qmail that has a multitude of smaller programs for each function instead of one huge program that does everything. This allows for greater speed and flexibility. John R. Levine's new book "qmail: Managing Unix-Based Mail Systems" examines the qmail program in depth from installation to configuration to troubleshooting. While qmail is fairly straightforward and you can achieve great results on both small and very large systems, it is a very different way of thinking if you are moving from sendmail and are already familiar with it. The author recognizes this difficulty of changing the way you think and spends a good portion of the beginning of the book detailing qmail and how it works so you understand the "qmail frame of mind". I've never setup a sendmail server and so I did not have the obstacle to overcome but I have setup and configured the postfix MTA which is also a modular type program. With that background the book was a breeze to follow along and I was even able to download a copy and configure it correctly for my system. The coverage was excellent and the installation and configuration information provided all the information I needed to get it up and running. If you are thinking of building a qmail MTA you will find "qmail: Managing Unix-Based Mail Systems" absolutely indispensable and the only reference you need to get it done right the first time.

The handbook that is long, long overdue...
2004/4/11
形式:ペーパーバック
For years, any system administrator running Linux who was worth his paycheck knew that Qmail was the defacto standard for running a mail server (heck, even Yahoo uses it!). Sendmail has always been ripe with security holes and headaches -- something Qmail has went to great lengths to correct. However, the problem has always been there was no easy reference guide to Qmail. You had to be either a Linux-geek, or know someone who was, to get it installed and working correctly!
Now, thanks to O'Reilly, even us non-geeks can get our Qmail systems up and running in no time. This book covers everything you need to know in an easy-to-follow format. From installation, to making the switch from sendmail, even how to tune and setup third-party components with Qmail to help control spam, scan for viruses and run your own mailing list server.
One of the great things about this book is it, for the most part, is not dependent on any particular flavor of Linux. The author does a good job of making it generic enough that you can follow along no matter what distribution you use.
Granted, you will need to know a bit about Linux to use read and fully understand this book. It is geared towards system admistrators and not the end-user of a Qmail system. However, you don't need to be a Linux Guru to understand it -- it has just enough detail to satisfy without overwhelming.
Overall, this is the handbook for Qmail that has been long overdue -- a one-stop technical manual that puts the final touch on Qmail.
