While it's true that a c/r system which whitelists senders is spoofable, that's not a characteristic of all c/r systems. For example: a c/r system which only lets a single message through for each c/r a c/r system which whitelists pgp keys (allowing through messages signed by them). Both of these require a significantly higher commitment to dealing with incoming email than current spammers have exhibitted. -- Raul
