XFOR: Internet Mail Service Stops when Routing Messages

ID: Q197142

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

If the Internet Mail Service is configured to forward messages to another Microsoft Exchange Server computer, and an input/output (I/O) error occurs while the Internet Mail Service is attempting to forward a message using the EHLO command, the Internet Mail Service may stop unexpectedly. For example, if the Internet Mail Service sends an EHLO command to the second server, and then the second server ends the connection before sending a response, the Internet Mail Service may stop unexpectedly.

CAUSE

When an I/O error occurs under these conditions, the Internet Mail Service may not recognize that routing is being performed. As a result, it may use an incorrect address that is NULL.

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:
