Godaddy Email Server being blocked by Spectrum

I am having problems sending any email from my GoDaddy Domain email ( to any email associated with Spectrum ( aka roadrunner. 

The message I am getting when sending to one of these addresses is


Delivery to the following recipients failed permanently:


Reason: There was an error while attempting to deliver your message with [Subject: "Test Email No. 2"] to MTA received this response from the destination host IP - - 552 , 552 5.2.0 ESMTP server temporarily unabailable AUP#I-1510

Of course when I contact Spectrum, their help desk says there is nothing they can do but suggested that I tell recipients to put the domain in their allowed email addresses in the advanced settings.  I tested that with one recipient and it still didn't work.   Even so, how do I get my Godaddy domain off Spectrum's blocked list.


I have the same problem. Whenever I want to send to a address, I have to use my gmail account.
