I'm trying to setup a new email address on my dedicated server (looks like I hadn't sorted this in the past for this domain and server). So I have the following
1. Domain registered with 123-reg
2. Using FreeDNS for the name servers
3. FreeDNS is pointing the main domain to the dedicated server IP as an A record (selected subdomains elsewhere)
4. Dedicated server is running ISP config and has an email server running
What do I need to setup on FreeDNS? MX records? Subdomains?
