How to recover email

Hi, I wanted to play some games with my old character here, but couldn´t log ingame. For reason unknown to me, you reset our passwords every so often and send it to linked email. As it happens I believe with many people, I only created the email (gmail) for the purpose of creating an account here and I forgot what the email is. So now I can´t log my account because my password was for some reason reseted and I have no idea what email I used.
Is there any way I could get my email adress? I know every other info, my old pass, acc, you can check ip and whatever, I´d just like to play ..thanks
