Are you receiving dozens of emails each day? Feeling overwhelmed? Do you want something that will make your life easier? That will separate personal email from work email? Then Procmail Companion will show you how to control your email rather than your email controlling you. Procmail is a program that can automatically process electronic mail. It is small, fast, secure and free! It runs on Unix and Unix-like systems and is growing in popularity. It kicks in after the mail arrives on your machine and before you read the mail. With a few simple sets of instructions, or recipes, Procmail puts all messages from a photography mailing list into one mailbox and all mail from a particular set of friends into another. Emails that tell you how to 'make money fast' or asking if you would like 'to buy a time share' are thrown away and don't waste your time. This book provides pain free explanations about how to use and get the most from Procmail. Using case studies, explanations and examples this book will teach new users how to use Procmail and give advanced users tips and tricks on the more esoteric features of Procmail.
