MX record IP address instead of hostnames
Can anyone tell me why my MX record for the coop-uspto.gov domain are IP addresses instead of hostnames?

Re: MX record IP address instead of hostnames
I suspect a operator error that has now been fixed. If you put IP addresses in the MX records, instead of hostnames, the current $ORIGIN will be appended which is born out by looking at the address records for the mail exchangers.
