Surely the question makes sense. But we can't answer it. Only the customer service of mail.com (or the help information on their site) can tell. So back to them.
Probably you'll have to proof that you are you indeed. If the hacker could do the same if you can (call them, have them unblock it and change the password) he would have the full account and you would have nothing.
Here is a rich question.
mail.com has locked me OUT, of my account. (Due to hackers sabotaging my content, across the internet).
Here is the fun part.
mail.com says that in order to recover my mail.com password, or change it, I must first, log into the account, which I am blocked from.
Now, my question is:
If I am barred from accessing my account, HOW do I access the account, in order to reset this password?
Does this question even make sense?
