Patent ID: 7206815

Claim:
A computer-readable storage medium carrying one or more sequences of instructions for synchronizing email between multiple computers, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform a method comprising the steps of: reading a first set of messages from a portable electronic device into a first personal computer; identifying an outgoing message in the first set of messages to be delivered from the first personal computer to a mail server; identifying on the first personal computer a second set of messages previously retrieved from a server, the second set of messages having, at least once prior to a previous event, a first message that matched a corresponding message in the first set of messages; comparing the first set of messages with the second set of messages to identify if at least the corresponding message in the first set of messages that matched the first message in the second set of messages was deleted or modified after the previous event; and automatically signaling the outgoing message to the mail server.
