The cost of spam is escalating for enterprises asthe amount of unsolicited e-mail being sent continues to reach new heights.Analysts estimate businesses lose up to $10 billion each year in lost productivityand services.Slamming Spam is an administrator's "how to" stop spam book. It is very handson,with none of the "why people spam" or other topics that are found in otherbooks and usually only peripherally interesting or useful to a mail administrator.Most books out there now are for end-users; this book is for in-the-trenchessys admins. The authors examine how anti-spam methods are implemented onthe client-side (covering Outlook, Outlook Express, Eudora, and UNIX mailclients), server side (covering Exchange and Lotus Notes), and outsourcedoptions including Brightmail and Postini. There is also coverage ofSpamAssassin, a widely deployed open source mail filter which uses a set ofrules to decide how probable it is that a piece of mail is spam.
