I trying to set up MX and A record for a list server on another host, but not quite got it right somehow. Currently the main domain is on JH. I need a subdomain address to work for the listserv; this has no website, it's just a mail server.
So if my main domain is mydomain.com the DNS for listserv.mydomain.com needs an A record to their IP, and a MX record to that subdomain name.
A record: listserv.mydomain.com>IP address
MX record: listserv.mydomain.com>listserv.mydomain.com
Should I create the subdomain on JH and change those DNS records in the subdomain DNS, or simply add listserv.mydomain.com A and MX records to the DNS for mydomain.com?
