I have wondered what locked account actually means in context of the mail and its configuration being "active". E.g. I have setup email forwarding in my Gmail so that I always get a copy at another address. When my account is locked, I know I can't connect to Gmail but what happens to the above "workflow"? Does Gmail stop receiving messages / forwarding rules no longer work?
