So  I have had one my original accounts hacked and email changed on it recently I have a question in regards to the email part.

I got an email off support saying I need to send email from original email on account. Is this the one that the account was originally made with when open or the one that it had on it before it got compromised as I had had a few email address changes made to the account over the years.

Can someone tell me if wanting one that was current on account before hacked or original opening email address used to open account with?
