I agree with Om on this, as spam keeps growing in proportion to emails sent, we need a new way to send email.

A new mechanism to verify the sender, to quickly blacklist and abolish spam and other erroneous messages needs to be created and implemented.  The existing email protocols don’t have anything within the messaging sending/receiving structure to validate a message.

Who’s up for the challenge!?!
