Removal of an mx record

[darth.bob.rules59]

My email is not working properly, it bounces back emails people try to send to me, I phones support for my email provider and they said that my hosting site needs to go into my mx records and remove one of the three records. The only two that should be in there are smtp.secureserver.net and mailstore1.secureserver.net. having the third one in there is causing emails to bounce.

cPanel --> Mail section --> MX Entry icon

Scroll down to the bottom of the resulting page to the list and you have a 'Delete' link.
