To address MX record misconfigurations, implement the following:

* **Correct Record Format**: Ensure all MX records follow the exact 'priority hostname.domain.tld' format.

     - Example:
     
          - `10 mail.example.com.`

* **Validate Priority Values**: Set integer priorities within the 0-65535 range, with lower values for preferred servers.

     - Example:
     
         - `10 primary-mail.example.com.`
         - `6553 secondary-mail.example.com.`

* **Manage Duplicate Records**: Ensure there are no duplicate records.

     - Example:
     
         - Incorrect:
             - `10 mail1.example.com.`
             - `10 mail1.example.com.`
         - Correct:
             - `10 mail1.example.com.`
             - `20 mail2.example.com.`

* **Verify Hostname Resolvability**: Confirm all MX hostnames resolve to valid IP addresses of active mail servers.

     - Example:
     
         - For `10 mail.example.com.`, ensure the domain is resolvable to a valid IP address, e.g.:
             - `mail.example.com.  IN A   203.0.113.1`

* **Align with SPF Records**: Include all MX hostnames in the domain's SPF record.

     - Example:
     
         - The MX record `10 mail.example.com.` should be included in the SPF record, e.g.:
             - `v=spf1 MX ip4:203.0.113.1 -all`, where resolving the domain in the MX record would give us the ip `203.0.113.1`.
