XADM: NDR from Postmaster Incorrectly Formatted by IS
Article ID: 166501

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. For information on
obtaining the Service Pack, query on the following word in the Microsoft
