I was trying to find a book with clear instructions about how to configure sendmail under 7.2. Unfortunately this is the only book right now available in the market, and honestly I don't like it. I found more specific procedures on internet than in this book. For example, the Essencial Configuration section Part 2, should specifically indicate how to configure sendmail in order to make it work. Instead it wastes the time walking around one thousand things and not clearly. We need something more specific like Step 1 do this, Step 2, do this...., Usually the books after to complete a subject go over the details, that is better for the learning process.Regards...Piyux
