We are using Exchange 2003 with the latest service packs. Internal emails are not being delivered whenever an external email address is in the TO: or CC; fields along with the internal email address. The external email get delivered but not the internal. If just multiple internal addresses are used, everyone gets the mail but if one external address is included, nobody gets the internal mail. Message tracking doesn't indicate a problem, nothing in the event logs, nothing in the queues.

And your internal domain name (right side of @) is marked as an Authoritative domain in Exchange?

Authoritative and nonauthoritative domains in Exchange 2000 Server and in Exchange Server 2003

Yes it is marked as authoritative Jesper. We are using Google's Postini as our spam filtering service and with their DNS server entered in our external DNS server list. What may be happening is that our internal emails may be getting routed through Postini and not re-injected back and have contacted them about this problem as well. I would think Exchange should know when to route externally and internally based on the domain name (hence your question) and no internal emails would be sent through Postini.

What does Message Tracking say about a message that does not get delivered to internal recipients?
