Some years ago, I subscribed to an email forwarding system by the name of forevermail.com. This allowed me to change the ISP without changing my address. However, forevermail itself appears to have gone out of business. It has obviously left the forwarding addresses functioning on a server somewhere because the few users’ emails from users that have not changed to my address still arrive in my Outlook system. Do you know how I can remove this old address? I’ve tried mailing the domain owner, but I get no reply. With your advice, I have purchased my own domain and therefore, I control of my own address now.
In your scenario, there’s practically nothing that can be done. If a service that you rely on goes away, you’re basically out of luck. There really isn’t any protocol or particular leverage that you or I might have to do something with a company, website, or service that disappeared.
But I do have some suggestions on what you could do.
