you don't describe why this is is a problem, and hence why it should be
considered for backporting to stable kernels.

SOB doesn't match your From address. So you either need to change your SOB,
update your From address in your e-mail agent, or add a From: tag to you patch
so that From == SOB

your e-mail subject doesn't reflect that this is a v2, and it was threaded
instead of being sent as a separate e-mail thread.

when you send a v3 that addresses the above please make sure to use a properly
versioned subject and send as a separate thread.
