Abstract:
An e-mail system is disclosed that overcomes many deficiencies of, but is backward compatible with, existing e-mail systems. Embodiments of the system may include various features, including but not limited to: (1) secure transfer of e-mail messages, without the need for users to replace existing e-mail clients or to change e-mail addresses; (2) tracking of all actions performed in connection with an e-mail transmission; (3) the ability for a recipient to view information about an e-mail message, optionally including information about how other addressees have responded to it, before deciding whether to retrieve the e-mail message; (4) the aggregation of entire e-mail conversations into a single threaded view; (5) the ability to include both private and public messages in a single e-mail communication; (6) sender control over downstream actions performed in connection with an e-mail message; (7) flexible control over cryptographic methods used to encrypt emails messages for storage.

Claim (Index 4):
A secure messaging system comprising:\n a server system which provides a secure messaging service; a sender computing device running a messaging client; and a recipient computing device associated with a recipient address of a recipient; wherein the secure messaging system is configured to: intercept a message composed and sent by a sender via the messaging client running on the sender computing device with a messaging client plug-in running on the sender computing device, such that an ordinary transmission of the message to the recipient address is blocked; send the message in unencrypted form via a secure communications protocol from the sender computing device to the server system for storage thereon in encrypted form; send an introductory message in unencrypted form via an SMTP protocol to the recipient computing device, said introductory message including a key for retrieving the message from the server system in unencrypted form via the secure communications protocol, the key including a message identifier identifying the message and a service host identifier indicating to the recipient a network accessible address of the server system at which the message is stored, wherein the key does not serve as an encryption or decryption key, the key being further usable with the recipient address to programmatically register the recipient with the secure messaging service upon access of the introductory message by the recipient, wherein the introductory message lacks at least some message content of the message.
