The Virtual Bookcase Reviews of 'Sendmail (nutshell handbook)':

Sendmail might not be the heart of UNIX mail and communications services, but
it certainly is a good portion of the autonomic nervous system. Although
considered venerable by some, it is also extremely widely used. This book
hopes to make sendmail administration not only easy, but fun. Quite a task.
Part one of the book is tutorial in nature, starting with background
information in chapter one. We are given a brief history and philosophy of
sendmail, plus some description of the component parts, and the related
Internet RFCs (Request For Comment) and technologies. (RFCs, the name to the
contrary, are the descriptions of how Internet functions should work. In a
sense, they are the standards of the Internet.) Chapter two gives us some
examples of how "subnetworks" of machines within the Internet handle mail among
themselves, and introduces routing, very briefly. It takes its tutorial
function seriously: there are questions at the end of the chapter for you to
think about or try out. The questions get harder in chapter three, and start
requiring more knowledge of both UNIX and the RFCs, in order to deal with
headers and "envelopes". (Actually, the text is easy. Only the questions are
hard.) Chapter four introduces the various related programs that sendmail
calls and the functions it performs.
So it continues up to chapter fifteen. The tutorial covers the invocation and
switches, the configuration file, mail delivery agents, macros, rules, rules
and more rules, class macros, options, headers, and miscellaneous topics.
Part two deals with administration and management, and runs you through the
process of configuring, compiling and installing sendmail. It also has
specifics of V8 and IDA, as well as DNS (Domain Name Server). Topics covered
include security, the queue, aliases, mailing lists and forwarding logging and
Part three is the reference, and chapters twenty-three to thirty-three list the
options for delivery agents; defined, class and database macros; options,
headers, the command line and debugging. Finally, seven appendices deal with
queue file intervals, obscure error messages, the "define" macros in the
confi.h file, the client.cf file from the tutorial, V8 and IDA configuration
macros, and a bibliography.
Because of the nature of the book, you will find a fair amount of material
duplicated (for example between the tutorial on delivery agents, and the
reference sections). However, the duplicated material, and the short
chaptering make this an excellent reference work overall. The material is
generally clear and well laid out. The tutorial section is definitely for the
technically advanced: I suspect the authors have a ways to go before many
people find sendmail "fun".
