SYMPTOMS
When a user sends a message to an invalid or non-existent SMTP user, the originator of the message receives an NDR from postmaster%s_%g@site.org.com Where the %s_%g matches the wildcard used for the Microsoft Exchange Site's SMTP proxy address.



CAUSE
When the information store initializes, it queries the Directory Service for the SMTP proxy address. The information store keeps this address, in whole, in a global variable that is to be used with the Postmaster address. The information store incorrectly populates this variable with the entire SMTP proxy address rather than just the SMTP domain.



WORKAROUND
To avoid this problem, do not use wildcards in the site's global SMTP proxy address.



RESOLUTION
Apply the fix described in the "Status" section. In the fixed version, the information store was corrected to parse any characters to the left of the @ sign in the SMTP proxy address store in the Directory. The global variable is now populated with just the SMTP domain.



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.
