Question > I have just received an email from "redmail" saying that "the login page has changed" or "my account has been compromised" or similar. Is this genuine?
In short, NO .. Probably NOT. We will never email you randomly / out of the blue like this and if there is a problem / we have had to contact you, then we will be directing you to a support ticket in the web interface which you access from the "Billing" link within webmail. Never ever click on links in an email unless you are 100% certain you can trust the sender.
