There seems to be a problem with the SMTP server that the end user is using. He might need to use a smart host to correct the problem. Your Email server sees it as spam and rejects it.

I read the question wrong. Kindly check if the sender is using Exchange at their end. They might have listed the email as a contact which causes the loop back problem.

Does it happen with all email addresses or just one?

Either ways, its an issue from the senders side most likely. You can mail them the below link to verify the issue. The would first need to check every possible instance where your domain is listed.
