Do we have any estimates how many emails github sends every day? 400k might be a rather unnoticable increase on a global level? Edit: Of course if dozens or even hundreds of replies "Why am I on this list?", "Please (do what I say not what do) stop replying" go to 400k again then it gets "interesting". Could not see from the submission or discussion whether that happened. I think it should not happen by default or what kind of Reply-To: those messages have?
