XFOR: PCMTA Tries to Dial Up Asynchronous Connection for Downstream Postoffices

MORE INFORMATION

Given the following setup:

The Exchange Server computer has two Microsoft Mail (PC) postoffices connectedly directly to it, one via the LAN, the second one via an asynchronous connection. The first Microsoft Mail (PC) postoffice also has a direct connection to a third Microsoft Mail (PC) postoffice via a direct asynchronous connection.

1. Create a Microsoft Mail connection from the Exchange Server computer to PO1 and PO2.
2. On the MSMI properties page of the Exchange Server computer, select "Upload Routing" for PO2 to establish PO3 as indirect by way of PO2.
3. Create a Microsoft Mail (PC) MTA instance of type "Async and LAN" to service the Exchange Server computer, PO1, and PO2.
4. Send an e-mail message from the Exchange Server computer, destined for PO3.

Result

The Microsoft Mail (PC) MTA instance will attempt to send the mail using a dial-up connection to PO3, even though no information for reaching that postoffice is defined in Exchange Server.

Expected

The Microsoft Mail (PC) MTA instance should deliver the message to PO2 by means of the LAN connection, and not attempt to send it directly to PO3.
