SYMPTOMS
When the Microsoft Exchange Internet Mail Service is configured to refuse connections based on IP addresses, the Internet Mail Service issues Event ID 220 rather than Event ID 521. The message originator will not receive a non-delivery receipt (NDR) immediately with the message:   521 access denied Instead, the message delivery will be retried until it times out, and then an NDR is returned.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server, version 5.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
