Hi @sermorg. Thanks for being part of GoDaddy Community! Our cPanel interface has changed a little and our documentation hasn't quite caught up yet. Sorry. What was previously labeled MX Entry is now called Email Routing. If you click there, you should be able to select your domain and local or remote routing based on what you're using. Local = email is hosted on cPanel, Remote = email is hosted anywhere else. Hope that helps.
