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 delivery
- Administration covers all aspects of handling sendmail, from
downloading and installing new releases to managing mailing lists and
aliases
- Configuration Reference contains a heavily cross-referenced guide
for configuring and tuning sendmail. Every arcane detail of sendmail is
listed alphabetically
- Appendices contain more detail about sendmail than you may ever need
This 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.
