Actually, I added the IP to the MX record out of desperation. I have changed it back to the domain name and you can dig or do a dnsreport and see that it is fine. However, I am still getting the same error. I have pasted the full header at the bottom of the tickt.
For Jedito, I can ping kanatasmokehouse.com (domainname1.com) from marketing.ca (anotheruser.com) and I can also complete a tracert. They are on different servers but in the same data center.
