Query: Beats the bat

Until the O'Reilly "Bat Book" is updated and expanded, this book should become the standard sendmail reference book, for linux as well as other unicies...The information is cleanly laid out, explored and described. The author presents not only broad knowledge/information, but in depth experience with the MTA and related technologies.I found this book quite helpfull when stuck with the minutia of a sendmail.cf file, and the information in the beginning of the book in great for those new to sendmail and/or linux.
