You have two mail servers on your network named Mail1 and Mail2. You want clients to access Mail1 unless it’s unresponsive, and then Mail2 should be accessed. What should you configure?
The MX recoerd has a priority value that can be configured when you are using two mail servers on a network. The MX record has a preference system that can be used to prioritize the MX records of multiple mail servers on a network.
The mail server with greater preference number will be used first so in this case, we should configure the priority value of MX records to access Mail1 and then Mail2.
