As you can see, at your domain registrar, the IP for one of the Cloudflare DNS is wrong.
It should be: 108.162.193.91
And the MX.
Where to start with that.
Domain name is Invalid. Missing .com, .net, etc.
IP is missing.
Priority is usually either 0 or 10. 10 being the most common.
Also is showing not PTR setup. Which is OK, usually this is set to the hostname, and not the mail server.
