I would like to build a program in PHP to let both buyers and sellers communicate with each other via encrypted e-mail addresses. It is just like what Amazon does in its Buyer-Seller Messaging Service. Below is part of the description.
"By using the Buyer-Seller Messaging Service, both buyers and sellers communicate with each other via encrypted e-mail addresses. For example, if a buyer wants to contact a seller, the Buyer-Seller Messaging Service will assign an encrypted alias, such as "a222d34b3891234b@marketplace.amazon.com," instead of displaying the seller's real e-mail address. E-mails are routed to the seller via this encrypted alias."
Is it possible that the buyer replies emails to the encrypted email address of the seller, and the seller is able to receive these emails in the inbox of his real email address, vice versa?
Can anyone give me some suggestion on how to achieve it? Thanks a lot!
