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.

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.
