Abstract

Improved techniques for synchronizing different electronic mail mailboxes (accounts) of a user are disclosed. The user is able to effectively see and interact with only a single “virtual” mailbox, which is the synchronized combination of the two different electronic mailboxes. The electronic mailboxes are used to receive, store, read and send electronic mail over a network to electronic mailboxes associated with recipients. The electronic mail can include electronic messages that contain text, graphics or video. The synchronization of the two different electronic mailboxes can be performed automatically in a two-way manner without user interaction. The synchronization can also be performed securely even though electronic messages are transmitted over a public network.

Claims

1. A method for synchronization of a second mail system and a first mail system, the second mail system communicating with the first mail system through a public network, said method comprising:

maintaining a first inbox for the first mail system, the first inbox having a first message list associated therewith;

establishing a secure connection between the first mail system and the second mail system through the public network;

requesting a second message list from the second mail system over the secure connection, the second message list being associated with a second inbox for the second mail system;

comparing the first message list with the second message list to identify missing messages, the missing messages are those messages that are identified as being present in the second inbox but not also present in the first inbox;

requesting the missing messages from the second mail system over the secure connection;

receiving the missing messages from the second mail system over the secure connection through the public network; and

inserting the missing messages that have been received into the first inbox of the first mail system;

deleting at least one of the messages from the second inbox that are known to be present in the first inbox.

2. A method as recited in claim 1, wherein said method further comprises:

receiving at the second mail application over the secure connection, subsequent to said deleting, at least one message from the first inbox that is not already with in the second inbox; and

inserting the at least one message from the first inbox into the second inbox.

3. A method as recited in claim 1, wherein following said deleting and said inserting, the message list associated with the second inbox matches a least a first set of the messages in the message list associated with the first inbox.

4. A method as recited in claim 2, wherein the number of messages deleted by said deleting equals the number of messages inserted by said inserting.

5. A method as recited in claim 1, wherein said method further comprises:

subsequently receiving at the second mail application over the secure connection at least one message from the first inbox that is not already within the second inbox; and

subsequently inserting the at least one message from the first inbox into the second inbox.

6. A method as recited in claim 5, wherein following said subsequently inserting, the message list associated with the second inbox matches a least a first set of the messages in the message list associated with the first inbox.

7. A method for synchronizing a first inbox of a first electronic mail application with a second inbox of a second electronic mail application, the first electronic mail application and the second electronic mail application being connected through a public network, said method comprising:

obtaining an action entry from an action list, the action list indicating changes that have occurred at the second inbox since last synchronization;

preparing a synchronization action message based on the action entry;

sending the synchronization action message to the first electronic mail application through the public network so that the first electronic mail application is able to perform the synchronization action of the synchronization action message to render the first inbox more consistent with the second inbox;

receiving an acknowledgement from the first electronic mall application that the synchronization action has been performed; and

thereafter removing the action entry from the action list when the acknowledgement has been received.

8. A method as recited in claim 7, wherein the second mail application provides mail services to mobile devices in a wireless manner.

9. A method as recited in claim 8, wherein the mobile devices are mobile telephones with a display screen for viewing the second inbox.

10. A method as recited in claim 9, wherein the public network comprises the Internet.

11. A method as recited in claim 7, wherein the first inbox and the second inbox include messages, and

wherein said method further comprises:

deleting at least one of the messages from the second inbox that is known to be present in the first inbox.

12. A method as recited in claim 11, wherein said method further comprises:

receiving at the second mail application, subsequent to said deleting, at least one message from the first inbox that is known not to be present in the second inbox; and

inserting the at least one message from the first inbox into the second inbox.

13. A method as recited in claim 12, wherein following said deleting and said inserting the messages within the second inbox match at least a first set of the messages in the first inbox.

14. A method as recited in claim 12, wherein the number of messages deleted by said deleting equals the number of messages inserted by said inserting.

15. A method as recited in claim 7, wherein the action entry is one of READ, DELETE, SEND, INSERT, MOVE and MARK.

16. A method as recited in claim 7, wherein the first electronic mail application operates on a first mail server, and the second electronic mail application operates on a second mail server.

17. A method as recited in claim 16, wherein at least one of the first and second applications provides electronic mail services to wireless devices.

18. A method as recited in claim 16, wherein said sending and said receiving communicate between the first and second electronic mail applications over a dedicated connection through the public network.

19. A method as recited in claim 18, wherein the dedicated connection is a secure connection.

20. A method as recited in claim 19, wherein the communications over the dedicated connection use a network protocol chosen from the group consisting of HTTP, HTTPs and FTP.

21. A method as recited in claim 7, wherein the synchronization action message instructs the first electronic mail application to perform the synchronization action of one of READ, DELETE, SEND, INSERT, MOVE and MARK.
