I think there's a wrinkle here to do with @googlemail.com, which was the original domain name for users in the UK where 'Gmail' was trademarked by another company. I've seen some fairly convincing evidence to suggest that different people have been able to register fnamelname@googlemail.com and fname.lname@gmail.com and, for them, the usual rule that you can add a '.' anywhere before the @ doesn't hold true.
