Abstract

A scheme for redirecting e-mail messages and message attachments from a mail system to a mobile data communication device. In one embodiment, a method comprises one or more of the following: automatically detecting a data item including an e-mail message and a message attachment by a redirector component associated with the mail system; processing the data item for sending a first portion of the data item to the mobile data communication device via a wireless network; receiving a command message from the mobile data communication device at the redirector component requesting more of the data item; and sending a second portion of the data item including the message attachment to the mobile data communication device via the wireless network in response to the command message.

Claims

1. A method of redirecting e-mail messages and message attachments from a mail system to a mobile data communication device, the method comprising:

automatically detecting a data item including an e-mail message and a message attachment by a redirector component associated with the mail system;

processing the data item for sending a first portion of the data item to the mobile data communication device via a wireless network;

receiving a command message from the mobile data communication device at the redirector component requesting more of the data item; and

sending a second portion of the data item including the message attachment to the mobile data communication device via the wireless network in response to the command message.

2. The method as recited in claim 1, wherein the processing the data item further comprises separating the e-mail message and the message attachment.

3. The method as recited in claim 2, wherein the sending a first portion of the data item further comprises sending a portion of the e-mail message and information about the message attachment to the mobile data communication device.

4. The method as recited in claim 3, wherein the sending a portion of the e-mail message and information about the message attachment further comprises sending at least one of file name, file size and file type of the message attachment to the mobile data communication device.

5. A system for redirecting e-mail messages and message attachments from a mail system to a mobile data communication device, comprising:

means for automatically detecting a data item including an e-mail message and a message attachment upon arrival of the data item at the mail system;

means for processing the data item in order for sending a first portion of the data item to the mobile data communication device via a wireless network;

means for receiving a command message from the mobile data communication device requesting more of the data item; and

means for sending a second portion of the data item including the message attachment to the mobile data communication device via the wireless network in response to the command message.
