Acknowledgments

Bob Amen, Justin Mason, and Matt Riffle served as technical reviewers for this book. Any remaining errors, of course, are mine.

I have once again had the pleasure of collaborating with an excellent O'Reilly editor, Jonathan Gennick. The O'Reilly production crew for this book included Darren Kelly, Ellie Volckhausen, and Nancy Crumpton.

This book is dedicated to the developers and user community of SpamAssassin, for their fine work in helping to stem the flood of unwanted email.

Never-ending thanks to M.G. and Ari, who make it all worthwhile.
