Indeed it does - the only way to truly validate is to get that confirmation email through. On the flip side I do think there's some value in a service which provides a check on the domain - that way you can prevent someone typing in username@gmail.con by accident. But you'd have to actually implement it correctly. Would people be interested in something like this as service?
