MSE weekly email registration.

Dakota_2

I've had to change my email address as the spammers have got hold of the old one. I own my own domain, lets say I tried to register [EMAIL="dakota@joeblogs.co.uk"]dakota@joeblogs.co.uk[/EMAIL] (made up name). The registration process declares this to be an invalid email address. It would appear that the registration process rejects perfectly valid private email addresses. Can anyone at MSE towers shed any light on this please?
