So, server-name.domain-name.org is not your customer's server? If that is the case, the problem is on the recipient's side. There isn't anything you can do on your end. Your customer would have to contact the recipient and have the recipient's IT department investigate.

This error came from the sender of the e-mail.  The e-mail was not recieved by one of my users.  Sorry if i was not clear about that.

The investigation is going to have to take place on the sender's end. The sender should send the message again and the IT admin should watch the message queues to see what connection error is being thrown.

From what I can tell looking at that header, the message is never leaving their server. So if they ask if you have any record of the mesage getting to your server, the answer is most likely no. However you might search your firewall logs for their server's external IP address just to be sure.

The other question to ask would be does this happen for any address in your company, or just a specific one? Again, it points to more of a global problem on their end.

The error sounds like the message is never able to be delivered from their server's queue. This is different than an NDR indicating your server had rejected the message. So really, the troubleshooting has to be done at their server.
