Dave,

The program rbldnsd is an open source program used to publish 
reputations.  Unfortunately, inputs used to establish reputation provide 
nonlinear relationships when used to grant "forgiveness".  Forgiveness 
has become increasing important when dealing with the many compromised 
accounts.  Some simply now use a strategy of white-listing larger 
providers, but if everyone took that approach, email would quickly 
become useless as a service.  What can be said is that reputation is 
slow and as a result fairly ineffective at dealing with bot-net activity 
being emitted from otherwise "respectable" sources.
