SYMPTOMS
Messages sent from a foreign system to an MS Mail user via the MS Mail Connector of an Exchange Server computer are not valid address types for reply when they are received at the MS Mail postoffice. Foreign address types are any address type that the MS Mail postoffice does not have a gateway or access component installed for routing.



CAUSE
When the MS Mail Connector receives a message with a foreign address type, it will convert the address to an X.400 address with DDA (domain defined attribute) type and DDA value. The problem is that the X.400 address does not include the GDI (Global Domain Identifier) from the Exchange Server computer. When a client replies to the address, the MS Mail Connector will generate an non-delivery report back to the client as a non-routable address.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:

191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5.
