I am looking for some clarification on some DNS settings as I'm not a genius when it comes to this.
I'm specifically interested in what the @ record does and how it works.
Does this record supercede all records?
More specifically I have a site that I need to set an DNS entry in for both the www. and mail. settings. there is an @ record for these DNS settings as well. Each will go to a different server location and IP.
It seems that when I put a forward on for the www IP, it also affects the MX or mail. record as well. It's the darndest thing in that when forwarding gets put on, the MX record remains the same in DNS and when pinged, but their mail goes somewhere else (don't know where).
I'm wondering if the @ record is somehow superceding the MX record and sending both?
Open for input.
