I noticed when I create a new virtual server that it creates all the DNS records, such as ftp, mai,webmail, etc.
I host my DNS on a 3rd party so I have to do that manually on their end if I want to replicate the same stuff Virtualmin comes up with automatically…
Now here’s my question, what’s the advantage of using for example: “mail.domain.com” instead of just setting up an MX record on my root domain? here’s my current set up: on my root domain, I have an MX entry going to “mydomain.com.” which works like a charm.
Should I instead add the MX record to “mail.domain.com” on my root domain and create another host called mail.domain.com pointing to my IP? I guess is double work? unless there’s a good reason for creating a host named mail.domain.com?
