MX records changed; still not working

Our domains are hosted at GoDaddy.
We changed priority 10 and 20 MX records, and deleted priority 0 (which was set to smtp.secureserver.net). Settings are now as reflected in the screen capture attached/below.

Emails are still not being delivered to our account. We are receiving this error message:

Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain ............com by smtp.secureserver.net. [68.178.213.37]. 

What's going on?
