Sebastopol, CA--Reliable, flexible, and configurable enough to solve
the mail routing needs of any web site, sendmail has withstood the test
of time. In the process, however, it has achieved what many sendmail
administrators would argue was impossible: it has grown even more
complex. Even the most experienced system administrators have found it
challenging to configure and difficult to understand; its configuration
file has been called positively frightening. 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 (O'Reilly, US $59.95). Now in its
third edition, this best-selling reference will help readers master the
most demanding version of sendmail yet.
The new edition of "sendmail" has been completely revised to cover
sendmail 8.12. "Version 8.12 has more features, options, and
fundamental changes than any other release has," explains Costales. "To
understand all that is new, and how valuable these new things are, the
sendmail administrator will need a reference like this." The third
edition represents a massive rewrite of this respected reference.
"This edition omits the tutorial that the prior two editions had,"
notes Costales. "This was done because sendmail has moved away from a
human-editable configuration file and towards a macro-based
configuration. The old tutorial parts have been folded into the
relevant reference chapters so that a gentle startup is still
"sendmail, Third Edition" begins by guiding the reader 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, the book covers the day-to-day
administration of sendmail. This section includes two entirely new
chapters, "Performance Tuning" to make mail delivery as efficient as
possible, and "Handling Spam" to deal with sendmail's rich anti-spam
The next section of "sendmail" tackles the sendmail configuration file
and debugging. And finally, the book wraps up with five appendices that
provide more detail about sendmail than readers 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 an advance look at sendmail version 8.13
(expected to be released in 2003).
With "sendmail, Third Edition" in hand, the sendmail nightmare is over.
Readers can confidently configure this challenging but necessary
utility for whatever their systems require. This much anticipated
revision is essential reading for anyone facing the task of
