I’ve lost my master email password – how can I retrieve it?
Due to the encryption, your passwords cannot be retrieved. However you can reset the master password : postmaster@your-domain.com in your control panel. You can then use the new password to administer/change/view/etc. all your other email accounts.
When you first login to the control panel, choose the link:
Password: change
this will bring you to a page to set a new password. It will set the new password for several parts of you account – including the postmaster@your-domain.com password. After you change the password, go to the Email section and select “Configure your email accounts”
