Abstract: A method is described comprising: receiving an e-mail containing an original attachment at a data service, the e-mail addressed to a data processing device to which the data service is communicatively coupled, the data processing device having specified processing capabilities; converting the original attachment based on the specified processing capabilities to a format which the data processing device can process; receiving an e-mail response from the data processing device intended to include the original attachment; locating and reattaching the original attachment; and transmitting the e-mail message with the original attachment to its destination.

Abstract: A system for distributing electronic messages to a wireless data processing device is described comprising: a dispatcher to maintain a communication channel with the wireless data processing device, the dispatcher comprising a short term message queue for temporarily storing e-mail messages addressed to the wireless data processing device while the dispatcher attempts to transmit the e-mail messages to the wireless data processing device; and a long term message queue for receiving the e-mail messages from the dispatcher if the dispatcher is unable to deliver the e-mail messages to the wireless data processing device after a specified period of time or a specified number of attempts.

Abstract: A method for coordinating messages between an internal e-mail account and an external e-mail account is described comprising: retrieving specified e-mail messages from the external e-mail account and storing the messages in the internal e-mail account; mapping internal identification (“ID”) codes assigned to the e-mail messages by the internal e-mail account to external ID codes assigned to the e-mail messages by the external e-mail account; detecting that an operation has been performed on a particular e-mail message on the internal account; determining an external ID code for the particular message based on the mapping; and transmitting an update to update the external account, the update including the external ID code to identify the particular e-mail message and an indication of the operation performed in the internal account.
