PIN Secured Email and IM for Spam Elimination

1. A user chooses a PIN code (or codes) for their email/IM address.
2. The user gives out the PIN code with their email address to individuals that are acceptable correspondents (friends/family/etc)
3. The mail/IM server, stores the PIN code with the email/IM address and handles the authentication.
4. When an outside originator wants to send an individual an email/IM, they enter the user's email/IM address, followed by the PIN code.
5. The mail/IM server receives the email/IM along with PIN code and verifies that the email/IM address and PIN code are authenticated.
6. If the PIN code/email/IM address combination is invalid, the email/IM is either returned or denied/dumped.
7. If the PIN code/email/IM address combination is valid, the email/IM is processed and sent to the email/IM address.
8. With the use of multiple PIN codes/single email/IM address combinations, a user will know if someone has given out the PIN code fraudulently.
9. A single PIN could be given out to trusted family and friends, but a different PIN code could be given to merchants. If a user gives a unique PIN code to Merchant A, but Merchant B sends an email to the user with the same PIN code, the user knows one of two things, either Merchant A sold the PIN code or there was a compromise of the Mail server or other infiltration.
10. Management of PIN codes is handled on the client side, much like an address book.
