Ping the sender automatically | |||||||||||||||||
I'm not a techie, but why can't the major email programs ping the listed email address of all incoming email, and flag those that don't have a valid email address? By valid, not one that is pointed elsewhere, but is in fact who it claims to be? We could then filter out those who fail the ping, and eliminate much (but never all) spam with very few "false positives".

Email addresses function as accounts on a server, therefore, sending packets to an address would just result in a ping echo from the server. Spam accounts can be set up on hotmail, which is a valid email service, if you were to ping an address that sends out spam for hotmail, all you would really be doing is flooding hotmail with packets. Besides, even if you were to send packets to email addresses, I don't really see how that would determine if they were valid or not, it would just tell you whether or not the server is up.
