To deliver mail to a specific ip address a matching must be configured in the DNS system.?

To deliver mail to a specific IP address, the Domain Name System (DNS) must be configured with the appropriate mail exchange (MX) records. These records direct email traffic to the server responsible for handling messages for a domain. Additionally, the DNS should also include A records that map the domain name to its corresponding IP address. Proper configuration ensures that emails are routed correctly to the intended recipient's server.
