Incorrect email validation in feed validator

I'm trying to validate http://www.yapc2011.us/yn2011/atom/en.xml at http://validator.w3.org/feed/ but it says my email address is invalid. As the given email address is used on a daily basis to organize an upcoming open source conference, I know it to be valid. I would file a bug in the tracker, but it's full of spam and seems to be unmaintained.
