Part III, Appendixes, contains topic not directly germane to any particular chapter.
Audience and Assumptions
This book is primarily intended for system administrators who also administer email.
But not all Unix systems are managed by administrators. Many are managed by programmers,
network engineers, and even inexperienced users. It is our hope that this
book satisfies all of you, no matter what your level of experience.
The true beginner should begin with Chapter 1, skipping ahead as needed.
The beginning system administrator should probably start with Part I to learn how to
build, install, and administer sendmail, then skip ahead to topics of interest.
The experienced system administrator who wants to install and manage V8 sendmail
should read Part I first to gain the needed background. Then explore Part II to discover
further topics of interest.

xx | Preface
Unix gurus and sendmail specialists should find Part II to be of value (even Eric keeps
a copy on his desk). In it, every arcane detail of sendmail is listed alphabetically. For
example, in Part II you??™ll find a single chapter dedicated to options, with every
option listed and explained.
No matter what your level of expertise, the sheer size of this book forces us to
assume that you are familiar with the day-to-day system workings of Unix.
