WotLK I want to somehow enter my old account!

[manor250]

So the thing is that I created my account many years ago (probably 5-6), as I'm checking now account name is still active but when I entered the password it said that the password had expired and a new one is sent on e-mail, but sadly I'm not receiving any mail for that account, I'm thinking maybe I have used old e-mail, but I don't know which one, so is there a way to find out which e-mail is attached to my account?
