I'm trying to run the installer for iRedMail to setup a mail server on my DigitalOcean droplet. I've set up a mail server before, but not through this application. I am trying to setup the server to read off of mail.domain.com (an A name exists in CloudFlare's DNS records). There is also an MX record for "mail" as well.
The problem right now is that the installer will not let me continue as I need a FQDN, and it's saying I do not have it setup correctly.
Sorry about linking to pastebin, but CloudFlare would not let me post the content in here directly.
