Can you tell me why I am getting this message when emails are sent out? It doesn't do it to all emails, just some of them. We have Exchange 2003. Here is the message:

You do not have permission to send to this recipient. For assistance, contact your system administrator.

To determine if your exchange server is an open relay, look here:

I would pay particular attention to the "SMTP authentication and relaying" section. It is possible your system has been "flagged" as being an open relay. If so, then you may be on many block lists.
