The correct answer is: Check the Raw WHOIS information for the original record

The correct approach to check the old value of an MX record that was changed on a client domain is to examine the Raw WHOIS information for the original record. WHOIS databases contain registration details about domains, including their DNS settings, and any changes made are often recorded within those records. When an MX record is modified, the previous configuration can sometimes be traced back through the historical data available in the WHOIS records. This option provides a reliable method to verify what the MX record was set to before the change occurred. It's important to note that the availability of this historical data may vary based on the WHOIS service provider and the specific domain's registration history. While checking prior revisions can provide past configurations, it may not always include detailed DNS settings, making Raw WHOIS a more direct source for historical MX record values.
