However, what spammers are really doing is adding SPF records to their
own throwaway domains. This in itself show that spammers are feeling
the pressure. It then requires yet another layer of complexity to track
reputation of domains once the forgeries are eliminated.
If you track reputation of domains, you still have the open decision how
to handle domains which have no data yet. I.e. how to detect and handle
spammers who register *new* domains for each spam run.
