Hm, that's really weird, I've been using <stable@...nel.org> for years and 
the commits do get picked up. I also never saw such a mailer failure.

In any case I've changed my pre-cooked alias to <stable@...r.kernel.org>, 
but still I'm wondering why <stable@...nel.org> seems to be working in 
practice - maybe Greg is picking up such commits as well, not via an email 
flow but via scripting?

Thanks,

	Ingo
