For now, said Linaker, nothing will change for existing users of Google's Gmail service in the U.K. and Germany, and even new users will be able to receive e-mail sent to addresses ending @gmail.com. That's because Google is using a single name space for the gmail.com and googlemail.com domains, so if someone registers the name [email protected], they also reserve the address [email protected], and vice versa, she said. Mail sent to [email protected] and [email protected] reaches the same mailbox, even for users outside the U.K. and Germany.
