Abstract
Abstract A way of synchronizing the contents of commonly-owned mailboxes (108, 111) in disparate messaging systems, such as an e-mail system (100) and a multimedia system (101), networked via the Internet (102). The e-mail system uses the existing auto-forwarding feature (115) of the Internet e-mail community to send a copy of every message arriving at the e-mail mailbox to the other system's synchronized mailbox. The other system applies a 3-part synchronization rule (113) to every message (200) arriving at its synchronized mailbox. If it detects a syncmark (204)--an identifier--of its own mailbox in the header (201) of the message, indicating that the message was previously copy-forwarded from this system, it just deletes the message. If it detects a syncmark or a pivot address of (any address resulting in message delivery to) the e-mail mailbox in any header field of the message other than the "From" field, indicating that the message is a new message copy-forwarded by the e-mail system, it stores the message in the synchronized mailbox but does not copy-forward it back to the e-mail mailbox. Any other message is a new message and is both stored in the synchronized mailbox and copy-forwarded, with the syncmark of the synchronized mailbox, to the e-mail mailbox. State changes of messages stored in each synchronized mailbox are detected and reported to the other synchronized mailbox, where like state changes are effected on corresponding messages.

Claim 6
Dependent Claim
67 words
The method of claim 2 wherein: the step of storing the received message in the first mailbox comprises the step of in response to determining that the received message includes an identifier of the second mailbox in a header field of the received message other than a message-source field, and does not include the identifier of the first mailbox, storing the received message in the first mailbox.
Claim 7
Dependent Claim
76 words
The method of claim 3 wherein: the step of storing the received message in the first mailbox comprises the steps of: in response to determining that the received message includes either a syncmark of the second mailbox or a pivot address of the second mailbox in a header field of the received message other than a message-source field, and does not include the syncmark of the first mailbox, storing the received message in the first mailbox.
Claim 8
Dependent Claim
23 words
The method of claim 6 wherein: the pivot address comprises any address that results in delivery of the message to the second mailbox.
Claim 9
