A side note about email. It seems you have To: email header empty which may increase chances to get these messages into spam. Again, I recommend to look at the implementation of my script [1] which I use on daily-basis and re-use it or taking an ideas how to send patches to the Linux kernel mailing lists. Alternatively you may study `b4` tool, it also has something like that in recent versions.
