Well, how does the current version of DCC that only works on unique messages
work so well?  Clearly, they must be avoiding the poisoning issues
effectively.  We see very little spam coming though our commercial anti-spam
gateway which heavily relies on the current DCC.  If I can get a DCC that
will identify abusive SenderID domains, that would be awesome.
