No morewading through pages of dense documentation and tutorials andcreating your own custom solution--just go directly to the recipethat addresses your specific problem. Each recipe in thesendmail Cookbook outlines a configuration problem, presentsthe configuration code that solves that problem, and then explainsthe code in detail. The discussion of the code is critical becauseit provides the insight you need to tweak the code for your owncircumstances. The sendmail Cookbook begins with an overviewof the configuration languages, offering a quick how-to fordownloading and compiling the sendmail distribution. Next, you'llfind a baseline configuration recipe upon which many of thesubsequent configurations, or recipes, in the book are based.Recipes in the following chapters stand on their own and offersolutions for properly configuring important sendmail functionssuch as:
