Review by Billy Barron

"Sendmail Desktop Reference" by Costales & Allman (O'Reilly; ISBN 1-56592-278-6) is a 68 page pamphlet on Sendmail. By no means, is it designed to teach you sendmail. The purpose of this desktop reference is for the person who already knows Sendmail, but does not have all the little details memorized and doesn't want to carry around the massive tome Sendmail.

It contains the command-line flags, configuration macros, options, rules sets, database elements, and other such information. Though I am generally not a fan of these small reference type books, this one shines above most of them by covering enough material in enough detail to actually be useful. System administrators who move around a lot will find this a useful addition to their library.
