3. The method of claim 2 , further comprising, prior to obtaining the reduced first email message:

receiving the preference data for the first mobile communication device from the first mobile communication device, the preference data for the first mobile communication device including the preferred format for the user of the first mobile communication device;

storing the preferred format for the user in the database.

4. The method of claim 1 , wherein the versions include a version in an HTML format and a version in a plain text format.

9. The method of claim 1 , wherein the reduced first email message includes a single version.

10. The method of claim 1 , wherein the reduced first email message includes the version that is a preferred version.

11. A server for optimizing the delivery of email messages to mobile communication devices, the server comprising:

a controller comprising at least one processor for controlling the operation of the server;

an email service, connected to the controller, for receiving email messages containing at least two versions of content, each version being in a different format, the email service being configured to:

for a first email message, destined for a first mobile communication device, the first email message containing a first version of first content and an alternative version of the first content, the alternative version of the first content being in a different format than the first version of the first content:

obtain a reduced first email message from the first email message, the reduced first email message containing the first version of the first content and having fewer versions than the first email message; and

send the reduced first email message to the first mobile communication device;

for a second email message, destined for a second mobile communication device, the second email message containing a first version of second content and an alternative version of the second content, the alternative version of the second content being in a different format than the first version of the second content:

select the alternative version of the second content based on preference data for the second mobile communication device;

obtain a reduced second email message from the second email message, the reduced second email message containing the second version of the second content and having fewer versions than the second email message; and

send the reduced second email message to the second mobile communication device.

12. The server of claim 11 , further comprising a memory, having the preference data for the first mobile communication device stored therein.

13. The server of claim 12 , wherein the preference data for the first mobile communication device is stored on a database on the memory.

14. The server of claim 12 , wherein the email service is configured to:

receive the preference data for the first mobile communication device from the first mobile communication device over the wireless network, the preference data for the first mobile communication device including the preferred format for the user of the first mobile communication device; and

store the preference data for the first mobile communication device for the user in the database.

15. The server of claim 11 , wherein the versions include a version in an HTML format and a version in a plain text format.

16. The server of claim 11 , further comprising a memory, and wherein the email service is configured to save the versions of the email message that are not included in the reduced first email message to a memory.

17. The server of claim 11 , wherein the reduced first email message includes alternative version information indicating the format of versions not included in the reduced first email message.

18. The server of claim 17 , wherein the email service is further configured to:

receive a request for a format of the first email message that was not included in the reduced first email message;

retrieve the alternative version of the first content from the memory; and

transmit the alternative version of the first content to the first mobile communication device.

19. The server of claim 17 , wherein the reduced first email message includes size information indicating the size of at least one of the versions that was not included in the reduced first email message.
