SYMPTOMS
When you send a message from your Exchange 5.5 Server computer to an MSMail recipient, you may receive a Non-Delivery Receipt (NDR) that is similar to the following:

The following recipient(s) could not be reached:  - 055SAO00 on

The recipient could not be processed due to congestion in the message transfer service MSEXCH:MSExchangeMTA:ACNUSSCH:ACNILMSX02

(091ACN08) on

The recipient could not be processed due to congestion in the message transfer service MSEXCH:MSExchangeMTA:ACNUSSCH:ACNILMSX02

However, you can send messages to and receive messages from other Exchange 5.5 Server users.



CAUSE
This issue may occur when you move mail from another mail server to this Exchange server, and then replay the mail. This issue occurs if mail is backed up on the bridgehead server so that it cannot replay and handle incoming mail at the same time.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. To resolve this issue, edit the registry on the bridgehead server to reset the   value to 0, and then stop and restart the Message Transfer Agent (MTA) service:  Click Start, and then click Run. In the Open box, type regedit, and then click OK. Click the following registry key:

 

 Click Parameters, and then double-click Dispatch remote MTA messages in the right pane. In the Value data box, delete the current value, type 0, and then click OK. Quit Registry Editor.</li> In Administrative Tools, click Services.</li> Right-click Microsoft Exchange Message Transfer Agent, and then click Stop.</li> After the service stops, right-click Microsoft Exchange Message Transfer Agent, and then click Start</li></ol>
