MX records (or A mail exchanger) are DNS records used to specify the mail server responsible for accepting incoming mail sent to a domain name. They must always point to a domain, never an IP address. You will only receive emails if your MX records point to the correct location.
A typical MX record contains the domain name, Time to Live (TTL), record type, priority, and the mail server hostname as shown respectively:
The record with the lowest priority value will be given the highest preference when you have multiple MX records. For example, an MX record with a value of 2 has a higher priority than an MX record with a value of 7. A “0” (as seen from the example above) represents the highest priority possible. If you only have one MX record, any value is acceptable for priority.
