A classic O'Reilly title since 1993, sendmail now covers Versions 8.10 through 8.14 of this email routing program, including dozens of new features, options, and macros. This edition also takes a more nuts-and-bolts approach than its predecessors. It includes both an administration handbook and a reference guide that provide you with clear options for installing, configuring and managing sendmail's latest versions and companion programs.The sendmail program has withstood the test of time because of its ability to solve the mail-routing needs of all sites large or small, complex or simple. But it's also difficult to configure and even more difficult to understand. That's why this book has proven valuable since the dawn of email. With it, you will be able to configure the program to meet any need, so that you never again have to call in a sendmail guru to bail you out.sendmail includes the following sections:Some Basics is especially useful for people new to the program. It covers the basic concepts underlying mail delivery and the roles sendmail plays in that deliveryAdministration covers all aspects of handling sendmail, from downloading and installing new releases to managing mailing lists and aliasesConfiguration Reference contains a heavily cross-referenced guide for configuring and tuning sendmail. Every arcane detail of sendmail is listed alphabeticallyAppendices contain more detail about sendmail than you may ever needThis edition also includes new material on SSL and AUTH and a new chapter on Mitlers. If you're interested in what has changed since the last edition, one appendix categorizes the many improvements of sendmail's intervening versions by chapter, complete with references to the appropriate sections and page numbers in the book.With sendmail, system administrators, programmers, network engineers, and even inexperienced users will be able to match this challenging but necessary utility to the needs of their network.
Reliable, flexible, and configurable enough to solve the mail routing needs of any web site, sendmail has withstood the test of time, but has become no less daunting in its complexity. Even the most experienced system administrators have found it challenging to configure and difficult to understand. For help in unraveling its intricacies, sendmail administrators have turned unanimously to one reliable source-the bat book, or sendmail by Bryan Costales and the creator of sendmail, Eric Allman. Now in its third edition, this best-selling reference will help you master the most demanding version of sendmail yet.
The new edition of sendmail has been completely revised to cover sendmail 8.12-a version with more features and fundamental changes than any previous version of the Unix-based email routing program. Because the latest version of sendmail differs so significantly from earlier versions, a massive rewrite of this best-selling reference was called for.
The book begins by guiding you through the building and installation of sendmail and its companion programs, such as vacation and makemap. These additional programs are pivotal to sendmail's daily operation. Next, you'll cover the day-to-day administration of sendmail. This section includes two entirely new chapters, "Performance Tuning" to help you make mail delivery as efficient as possible, and "Handling Spam" to deal with sendmail's rich anti-spam features. The next section of the book tackles the sendmail configuration file and debugging. And finally, the book wraps up with five appendices that provide more detail about sendmail than you may ever need. Altogether, versions 8.10 through 8.12 include dozens of new features, options, and macros, and this greatly expanded edition thoroughly addresses each, and provides and advance look at sendmail version 8.13 (expected to be released in 2003).With sendmail, Third Edition in hand, you will be able to configure this challenging but necessary utility for whatever needs your system requires. This much anticipated revision is essential reading for sendmail administrators.

Rezension zu „Sendmail “
"Für dieses Buch sollten Sie sich eine Menge Zeit und noch mehr Gehirnzellen reservieren, denn dieses Buch ist wieder einmal ein OŽReillisches Meisterwerk, was dem Leser einiges abverlangt. Ich denke man kann es schon als die Referenz im Bereich Sendmail bezeichnen, was auch die Mitarbeit eines der Sendmail-Entwickler belegt. Dieses Buch enthüllt einem mit seinen fast 1000 Seiten jedes Geheimnis von Sendmail und hilft einem die Sendmail.cf-Datei besser beziehungsweise überhaupt zu verstehen. Trotz seiner vielen guten Eigenschaften, hat dieses Buch natürlich auch seine Nachteile. Für Anfänger und/oder Fortgeschrittene ist dieses Buch nicht zu empfehlen. Allerdings sollten es Profis und Experten lesen, wo es in jedes Regal eines Systemadministrators gehört, auch wenn diese ein anderes Mail System administrieren, wie zum Beispiel Postfix. Sollten Sie allerdings über nicht ausreichende Englischkenntnisse verfügen, dann sollten Sie sich die fast 50 Dollar besser sparen. Das Buch verdient es gelesen zu werden und viele werden dieses auch ein zweites Mal tun. Hat man die Hürde geschfft und es durchgelesen, so eignet es sich danach auch wunderbar als Nachschlagewerk. Man sollte dann in der Lage sein, eine komplette Mail Domain einzurichten. Wörter wie sendmail.cf, Aliases oder .forward werden keine Fremdwörter mehr für Sie sein. Den Umfang dieses Buches kann man mit ruhigem Gewissen als `erschlagendŽ bezeichnen, denn diese Bezeichnung ist wirklich nicht übertrieben. Ich habe für das Durcharbeiten gute 2 Monate benötigt und denke, die sollte man auch veranschlagen. Darüber, ob der Preis von $ 49.95 / 59,92 Euro gerechtfertigt ist, kann man geteilter Meinung sein. Für Sendmail Administratoren ist es eine unersetzliche Hilfe, aber diejenigen, die sich noch nicht für ein Mailsystem entschieden haben, sollten die Rezension von `Das Postfix BuchŽ lesen, um eine Entscheidungshilfe zu haben. BuchTest.com-Fazit: Ein Buch für lange Winterabende!" -- www.BuchTest.com, 01/2003, Timo
