Explanation:
The mail exchanger (MX) resource record shows the DNS domain name for the computer or computers that process mail for a domain. If multiple mail exchanger (MX) resource records exist, the DNS Client service attempts to contact mail servers in the order of preference from lowest value (highest priority) to highest value (lowest priority).
