Fwd: please stop the spam on php-webmaster

I need someone to turn off the php-webmaster mailer, like now. I tried to change author info on commits i've made - which worked fine - but then blew up the mailer. I tested this on other github repositories and was like a transparent change, all is fine, unless clearly there's a mailer connected to your repo and it goes nuts. Can someone please help!, I'm literally sitting here watching all the emails rolling in and can't do anything about it :-( Many thanks, Paul
