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:

STATUS

version 5.5.
MORE INFORMATION
After you apply the fix, if an input/output error occurs while the Internet
Mail Service is attempting to forward a message using the EHLO command, the
Internet Mail Service does not stop unexpectedly, and attempts to resend
the message using the HELO command.
