How to stop email spam:

One unique feature of spam: The sender is almost always spoofed. This
solution works in that case (If it is not, we can always trace it back to
its sender, so there are easier ways to deal with that)

1) Before the email gets sent from the server , it must record {sender
email address, hash, recipient email address} for each email to be sent.

a. hash -> Just a hash of the email to (relatively) uniquely identify
the contents of the email

2) The server sends the email

3) When receiving server gets the email, it must:

a. Generate a hash for the received email

b. Send a CONFIRMATION back with the {sender email, hash, recipient
email} information.

i. If the server
recognizes the set, it will return a message saying that it was a valid
email, and email is delivered to recipient. -OR-

ii. If server does
not recognize the set, it sends a message back saying that the email was
spoofed, and the email is deleted and never delivered to destination

The beauty of all this is that you don’t need to worry about valid messages
being accidentally deleted. Even in the case where a server crashes and
loses it’s {sender email, hash, recipient email} list, you can actually
still ensure no messages are lost.

Now, this algorithm would need to be incorporated into a protocol.

It’s all pretty simple. The problem with this solution is that ALL email
servers must implement this in order for this to work, so it must be made
part of a new protocol, such as the next version of POP or SMTP, for
example. So it would take a few years before it could destroy spam. But what
a wonderful day that would be, for all of us.
