But if you telnet from an IP that is not registered, you would be denied. Thus at least eliminating many of the erroneous email servers out there on the DSL, dial-up and other broadband connections, this has been tried in the open with such things as MABS RBL, etc by blocking common spamming IP's and mail servers. But since it is not mandatory, it falls apart too easily.

I agree with you it's a hard problem to solve. But unless there is mandatory cooperation within mail server software (which can be monitored) to interface with a registry of acceptable/registered sites, then this model could work.

I can telnet to a mailserver and send mail to that host without much thought. What good will a registry do? What will solve spam is getting some of these virus writers to actually write some code that will trash disks of poorly patched (if a at all) hosts. Let Darwin take over. -Joe
