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 tools that round out a fully scalable and highly secure email system. These tools include POP, IMAP, LDAP, MySQL, Simple Authentication and Security Layer (SASL), and Transport Layer Security (TLS, an upgrade of SSL). A reference section for Postfix configuration parameters and an installation guide are included. Topics include: - Basic installation and configuration
- DNS configuration for email
- Working with POP/IMAP servers
- Hosting multiple domains (virtual hosting)
- Mailing lists
- Handling unsolicited email (spam blocking)
- Security through SASL and TLS
From compiling and installing Postfix to troubleshooting, Postfix: The Definitive Guide offers system administrators and anyone who deals with Postfix an all-in-one, comprehensive tutorial and reference to this MTA. |

Colophon Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of Postfix: The Definitive Guide is a dove. Doves belong to the class Aves (birds) and the order Columbiformes (doves and pigeons), to which the now-extinct dodo bird (Raphus cucullatus) also belonged. Their family, Columbidae, includes over 300 species of pigeons and doves, including the common rock dove or feral pigeon (Columba livia). In 1679, the French astronomer Augustin Royer discovered the dove-shaped constellation Columba. A constellation in the southern hemisphere, located near Puppis and Caelum, Columba's stars were originally part of the constellation Canis Major. Reg Aubry was the production editor and copyeditor, and Matt Hutchinson was the proofreader for Postfix: The Definitive Guide. Colleen Gorman and Claire Cloutier provided quality control. Mary Agner provided production assistance. Ellen Troutman-Zaig wrote the index. Ellie Volckhausen designed the cover of this book, based on a series design by Edie Freedman. The cover image is an original illustration created by Susan Hart. Emma Colby produced the cover layout with QuarkXPress 4.1 using Adobe's ITC Garamondfont. David Futato designed the interior layout. This book was converted by Joe Wizda to FrameMaker 5.5.6 with a format conversion tool created by Erik Ray, Jason McIntosh, Neil Walls, and Mike Sierra that uses Perl and XML technologies. The text font is Linotype Birka; the heading font is Adobe Myriad Condensed; and the code font is LucasFont's TheSans Mono Condensed. The illustrations that appear in the book were produced by Robert Romano and Jessamyn Read, using Macromedia FreeHand 9 and Adobe Photoshop 6. The tip and warning icons were drawn by Christopher Bing. This colophon was written by Leanne Soylemez and Reg Aubry. |
