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.
