Right! But I'm afraid I can't fix that. When I receive an email, I associate it with the address that GMail reports to me,, and when you sign in as something+something@gmail.com, the email address differs (as you might already guess). I know that I can safely remove +something but I can't be sure that it will work the same for every email service and ensure security. Please use something@gmail.com, I won't send you anything unless you explicitly ask for it.
