Description
An NDR could not be sent. This is most likely because the original message had a blank originating address. In most cases this is normal behavior, although it can sometimes  indicate a local or remote server configuration problem. If archiving was enabled at the time of failure, you should be able to find the failed message in the file: <file name>.
Comments

1. Open the Exchange 5.5 Administrator program.
2. Open the properties of Internet Mail Service.
3. Click on the "Diagnostics Logging" tab, and increase the logging level of "Message Archival" to maximum".
