Hi @PeterVentura, the MX records you should be using with your domain would depend on where your email server is hosted. Additionally, the issue with Wordpress not sending emails may be related to the plugin you're using, or the destination email address that you've configured. It would require a bit more research to determine what is actually causing the problem you've described. Your best bet for getting this resolved would be to reach out to our live support teams so we can review your account to see what you've got configured and where your email is hosted. Please give us a call at your earliest convenience: https://www.godaddy.com/contact-us.aspx. Thanks!
