WTF? How did we get on that? AFAIK, the only e-mail is if you tell the forum to do notifications, and I guess the wiki registration. I'd consider turning off the forum notification e-mails, I don't know why we have that.
The PBL blocks all hosts that it believes "should not" be sending mail, without any regard for whether it's actually spamming. Whoever owns the bitcoin.org IP address can request removal
