Thank you. It turned out that the domain we were sending to did not have their MX records set up correctly. Their primary mx record was resolving to an IP address and not an A record..
As they did not want to fix this I had to add all their 6 mx records and addresses to our hosts file and then we were able to send successfully.
Thanks.
