Technical Forgotten e-mail address

Greetings Warmane staff members.

I have another account that i don't remember the e-mail. Last i played both my accounts was around august/september 2016. Then i stopped playing for 2 years and when i came back, both the passwords on the accounts were reset. I retrieved the password from this account because i knew the e-mail address but for my other account i could not do it. So i would like to ask you to help me retrieve the account or at least tell me the e-mail. To prove that the account is mine i can provide the account name, last used password, some of the IP addresses that the account was logged from, last name of the main character + the name that i changed it too. I can provide other information about the account too if needed.

Please contact me, i am waiting for your respond
