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.

Claims

1. A computer-implemented method of providing different versions of an e-mail message to different recipients, the method comprising:

detecting a send event of an e-mail message composed by a sender on a sender computing device, said e-mail message being addressed to at least a first recipient and a second recipient, wherein the e-mail message includes a non-private message portion that is not private to any particular recipient, and includes a private message portion that is private to the first recipient;

securely transferring the e-mail message to a server system, and storing the e-mail message on the server system such that both the non-private and private message portions are stored in association with a common message identifier; and

providing restricted access to the e-mail message as stored on the server system such that the first and the second recipients have access to the non-private message portion, and such that the first recipient but not the second recipient has access to the private message portion.

2. The method of claim 1, wherein the step of securely transferring the e-mail message to the server system is performed with an e-mail client plug-in running on the sender computing device.

3. The method of claim 2, wherein the e-mail client plug-in blocks an ordinary transmission of the e-mail message from the sender computing device.

4. The method of claim 1, wherein the step of securely transferring the e-mail message to the server system is performed via a web-based e-mail interface.

5. The method of claim 1, wherein the method comprises communicating the e-mail message from the sender computing device, via the server system, to at least the first recipient without using a store-and-forward model.

6. The method of claim 1, wherein the step of providing restricted access to the e-mail message comprises presenting the non-private and private message portions to the first recipient in a single logical e-mail message.

7. The method of claim 1, further comprising receiving reply messages from at least some of the recipients, and storing the reply messages on the server system in association with the common message identifier.

8. The method of claim 7, further comprising representing the reply messages collectively as a single inbox entry presented to the sender.

9. The method of claim 7, further comprising combining the reply messages into a single logical e-mail message presented to the sender.

10. The method of claim 1, further comprising sending notification messages to the first and second recipients with information for accessing the e-mail message as stored on the server system.

11. A computer-implemented method of providing different versions of an e-mail message to different recipients, the method comprising:

detecting that an e-mail message being composed by a user via an e-mail client program is addressed to at least a first recipient and a second recipient; and

in response to detecting that the e-mail message is addressed to the first second recipients, supplementing an e-mail message composition user interface of the e-mail client program to include a first private message entry area for entering a private message to the first recipient, and a second private message entry area for entering a private message to the second recipient.

12. The method of claim 11, further comprising displaying, as part of said user interface, a first tab that is selectable to access the first private-message area, a second tab that is selectable to access the second private-message area, and a third tab that is selectable to access an area for entry of a message that is not private to any particular recipient.

13. The method of claim 12, wherein the e-mail message is additionally addressed to at least a third recipient, and the method further comprises, in response to the user dragging and dropping the first tab onto the second tab, generating a fourth tab that is selectable by the user to access a private-message area for entry of a private message to the first and second recipients.

14. The method of claim 11, wherein the method is performed by an e-mail client plug-in that runs in association with the e-mail client program.

15. A computer-readable medium having stored thereon an executable computer program capable of causing a computer system to perform the method of claim 11.
