A system and method for transmitting content such as electronic mail from a sending electronic device to a recipient electronic device. When content is to be sent, it is first determined whether the sending electronic device possesses a reference content item that has redundancy with the current content item. If so, it is determined whether the recipient electronic device includes a copy of the reference content item. If the recipient electronic device possesses a copy of the reference content item, a compression algorithm is used to compress the current content item, with the compression being based upon the reference content item existing in both the sending electronic device and the recipient electronic device. The compressed current content item is then transmitted to the recipient device, where it is decompressed and made available.
