All exchange server alerts are sent to my blackberry. I need a way to find out which computer keeps sending this e-mail that's undeliverable. I looked into the logs on my exchange server 2003 but was unable to find the ip of the computer that initially sent the e-mail. Does anyone know how I can find out which computer on my network is sending this e-mail?

The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.
