I have a server on 12.04.1 with ISPConfig3 and a few domains. Each of the domains forwards to my WAN IP which then forwards to my server on my local network. I am trying to get the MX records for the domains sent to my IP address.
My problem is my server doesn't have a FQDN, so I can't forward the MX records to my IP address. Any ideas on how to go about this? Also, in most tutorials you see the server hostname (/etc/hosts) as server1.example.com.
Should I use a FQDN here as well or could I call it server1.randomname? Any advice would be appreciated. Thank you so much for your time in advance.
