s/relays/proxies/ The proxies are tough to find since they can run on any port. Some of them even pick random ports, then "phone home" to tell the spammer which IP/port was just created as one of their open proxies.
my idea; a DC network that actively scans for active relays and tests them, it compiles a list on a daily basis of compromised IP addresses (or even addresses that are willingly allowing the relay) making this list freely available to ISPs via a secure and tracked site.
