Sendmail

If you take care of Sendmail servers, you should have this book. I've been using this application for almost 10 years, and I still learn new things all the time, and this book is primarily where I get my answers. Highly recommended.

If you are a mail admin and don't use this book, you are either doing it wrong or are a genius.Anyone who is serious about sendmail administration and configuration must use this book.sendmail is far to complex to be used w/o a great reference such as this.

Without a doubt, this is the best reference book there is on Sendmail. No other books come close.

Excellent update from the 2nd edition. Anyone who administers a Sendmail server needs this "reference" includes SMTP Auth, libMilter etc.I would suggest to the negative reviewers here to stick with a zero configuration solution such as iMail, this isn't a hold your hand setup text, it's reference. Sendmail requires some dedication, the learning curve is steep, but the rewards are great.

BUY THIS BOOK! If you have an earlier edition, throw it away and buy this book! If you looked at earlier editions and decided that they were not for you, forget the past ! Buy this book!The third edition is more than a new edition; it is a complete re-write that vastly improves the sendmail book. The second edition had 38 chapters spread over a 1,000 pages. All of the details were there, but they were so hard to find, the index was the most used section of the book. Not anymore! Despite adding 200 more pages of material, the book has been reduced to 25 logical, organized chapters. Each chapter describes an important function and covers that function in a step-by-step manner.The book is well organized, beautifully written, and a joy to read.
