SYMPTOMS

If you configure the Internet Mail Service on two Microsoft Exchange Server computers to use Secure Sockets Layer (SSL) without authentication, you may receive a non-delivery report (NDR) when you attempt to send mail from one server to another through the Internet Mail Service. The text of the NDR includes a 505 error and indicates that authentication is required for the message to be delivered.

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.5.
