This isn't something that's specific to this device, it's something that any device with a controller transfer size limit will benefit from so it should be done at the subsystem level instead. Please fix your mail client to word wrap within paragraphs at something substantially less than 80 columns. Doing this makes your messages much easier to read and reply to.
