How do I configure my DNS MX (Mail Exchange) records?

To receive email you must publish public records to the Internet stating where mail should be delivered. This is no different than publishing your address or phone number.
Typically the company ABC.com might publish records like "mail.ABC.com", but due to your managed email security and compliance you're first telling would-be mailees to drop of your mail at these servers where it's processed for spam, security, and compliance THEN these servers deliver it to your mail server safe and sound.
Take special note that these above records end in a period ("."). Depending on the means used to configure your DNS this may or may note be very important! Many configuration services may automatically append "ABC.com" to every record that doesn't explicitly end with a period. This would then publish web-kong.com.s8a1.psmtp.com.ABC.com which is entirely different AND INCORRECT. This will prohibit you from properly receiving email.
