How to Review MX Records Before Changing Email Delivery Priorities

Changing MX priorities can alter failover behavior or route mail to a server that is not ready to accept it.

Checks to make

Confirm each target is active, correctly configured, and intended as primary or fallback. Review TTL and provider guidance, validate TLS and mailbox handling, and test controlled inbound delivery before making priority changes.
