Theymos, the email I have setup now is the one I use daily, it is protected with two factor auth, so if the hacker somehow got in, they must have bruteforced or somehow got the password other ways. I have a copy of every single email on that email forwarded to a second account which has an even longer password then the first and is also two factor auth'd.
And to answer your question, yes it is under my control to the best of my understanding. (Not sure if old sessions still exist)
