Hello I added my  MX Records i the right way , the the panel says I  the are wrong, as you can see I added th same values you gave m, but I dont not why I'm getting the error  : " Error de verificación de MX  /  Error in MX verification"  I follow your steps to add MX records on hostgator.  (of cour i'm also getting the  "  553 Relaying disallowed. Invalid Domain" I guess because de MX are no verified)
