Editorial Reviews

From Barnes & Noble
The Barnes & Noble Review
Over the last few years, the venerable Sendmail has been challenged by new open source competitors that aim to be simpler, more secure, and/or more scalable. One of the most popular is Postfix, which began life in an IBM lab (and, when discovered by Lou Gerstner, set in motion the forces that led to IBM's open source strategy). Postfix's fast-growing user community will be thrilled to have Richard Blum's comprehensive book on running it.

If you need to know where to start (or how to migrate from Sendmail), you'll find exactly what you need here. If you're already running Postfix and want to fine-tune it for maximum performance or scalability, Blum shows you how. Whether you're an ISP serving corporations, or a business serving internal mail clients, you'll find content that's relevant to you. There's also an extensive section on advanced topics: supporting mail lists, configuring PPP servers, supporting dial-in clients, troubleshooting common Postfix problems, and more.

If you can make your way around a Linux box, you can have enterprise-class mail without the pain, or the cost. The software's free, and with the advice in this book, you can do it yourself -- no consultants needed.(Bill Camarda)

--Bill Camarda is a consultant, writer, and web/multimedia content developer with nearly 20 years' experience in helping technology companies deploy and market advanced products and services. He served for nearly ten years as vice president of a New Jersey-based marketing company, where he supervised a wide range of graphics and web design projects. His 15 books include Special Edition Using Word 2000.

    A book . . .A resource . . . A Real Find!

    I am the webmaster of a .COM that issues stock alerts--a great many alerts. Not being a programmer in depth, this book allowed me virtually an overnight understanding of what we were using and how to troubleshoot problems. Unfortunately, I never got to use it. Seems that the developers found out I had the book and it has not made it back to my desk in over a month! EVERY developer who deals with our alerts has had a chance with this book!
