We have noticed, and clients have also reported, a huge increase in a cPanel phishing email that looks genuine, but is far from it. The email suggests that your domain name has reached a quota which could affect your files and emails. It then entices users to click on links supposedly to auto extend your disk capacity for free as soon as possible in order to prevent the loss of any files and future emails. This is a SCAM EMAIL - do not click on any links!
