    All MX Servers are unavailable for domain ...

      Hi guys, hope I can harness the vast knowledge that the forums have to help me with a problem. We have Mcafee email security SaaS, through a vendor. Our vendor hasnt been helpful with our issue. With a series of about 4 different domains, we keep getting the following message bouncebacks:

       

      This message was created automatically by mail delivery software.

       

       

      A message that you have sent could not be delivered to one or more recipients.  This is a permanent error.  The following address failed:

       

       

        <[redactedemail]@uswulocal74.org>: 0 All MX servers are unavailable for domain uswulocal74.org

       

      I am an IT guy for a law firm and this is becoming problematic as the attorneys firmly believe its on our end while I'm not sure it is. A quick search of the forums mentioned something about Roadrunner and TWC emails not liking McAfee, but also said that was resolved.

       

      Any ideas?

       

      Thanks!
