In this situation, your mail server has refused the e-mail because it cannot identify the sender's domain (e.g. example.com) as a valid registered domain name. This is a common practice across most mail servers.

There may be a problem with the senders domain. More likely, there may be a DNS issue at your site.

Sometimes this sort of thing occurs when domains are moved from one ISP to another. You can get an inconsistent view of DNS where the Internet as a whole has one view of DNS, while a particular ISP (and all it's clients) get another view.

I recommend speaking with your technical support team. Get them to see what happens if they try DNS resolution for the senders domain on their e-mail server.

Also, this may have been a temporary issue that has since been resolved. If that's the case the technical support team won't see anything wrong. Try sending the message again to see if the issue has been resolved.
