Abstract
A method and system for the secure transmission of electronic mail from a sender device to a recipient device, where at an e-mail server an e-mail sent from a sender device is received, where the e-mail may be encrypted with a sender personal key, or transmitted over a secure communiation channel. The e-mail server may then, if the e-mail from the sender device has been encrypted, decrypt the sender encrypted e-mail with a sender server key to produce a server decrypted e-mail, and then encrypts the server decrypted e-mail with a recipient server key to produce a server encrypted e-mail. The e-mail server then transmits the server encrypted e-mail to a recipient device where the server encrypted e-mail is decrypted with a recipient personal key.
