Mail Host (SSL): mail.root

On my cPanel server, I noticed that users where being given the incorrect FQDN (Fully Qualified Domain Name, e.g example.com) for mail.root as the SSL address for the mail server. This is odd, since there is no where to actually configure the SSL host address. After a bit of poking around, it seems it sets the address based upon the address of your SSL cert. In my case, I was using a Wildcard SSL certificate from CACert (free SSL certificates). However, as the certificate was a wildcard certificate, it had no idea what the actual FQDN you wanted was! After purchasing a cheap RapidSSL cert for £10 and installing it, the SSL Host FQDN displayed correctly for users. Plus they won’t get any certificate warnings any more!
