We have a server which needs to receive mail to a subdomain of ours. Our main domain is altarum.org and the new server which needs to get mail is quickplace.altarum.org. Being new to DNS configuration, I'm not sure of all that I am missing.
The servers web page is able to be accessed but mail does not seem to be routed to it.
Here are the relevant zone entries:
quickplace.altarum.org. IN MX 10 quickplace.altarum.org
quickplace.altarum.org. IN A 184.108.40.206.
We can send fine outbound from that server, just inbound is the issue. So, it seems that the SMTP process is working fine on the server, it's just the DNS which is not configured right.
In my limited knowledge of DNS, I assumed that if a server is unable to resolved a name, it would go eventually to the root server, which would send the request to the proper name authority. Does this work for subdomains also? Or do I need to register this new subdomain?
