Looking up MX records...
MX records are DNS entries that tell sending mail servers which host should accept email for a domain. Without them, inbound mail has nowhere to go — domains that only send mail or skip MX entirely will not receive replies.
This domain has no MX records and cannot receive email.
The records above are listed in priority order. Sending mail servers try the lowest priority number first; equal priorities distribute load. The hostnames must themselves resolve to valid IPs — broken glue-records here are a common silent fault source.
Zero records means inbound mail is not configured. Multiple records at one priority give cheap redundancy. Vanity hosts (mail.<domain>) work as long as their A/AAAA records exist; verify them via the MX result page of those secondary domains if needed.
