The O'Reily _sendmail_ book is the most comprehensive about writing  
and debugging rulesets, although it is also rumored to have caused the  
deforestation of a small country due to it's size and page count.  Of  
course, the online documentation and FAQ available right there is  
probably enough for most people to get started.

[ Note: Having paid my dues and done my own share of sendmail ruleset  
hackery in the misty days of yore, I'm not sure I'd be willing to  
repeat that level of effort in the modern era where Postfix exists.... ]
