.bdr - Microsoft Exchange Non-Delivery Report Body

The BDR data files are related to Notepad. The BDR file is a Microsoft Exchange Non-Delivery Report Body File. When an e-mail message cannot be delivered, Exchange generates a non-delivery report (NDR) delivery status notification message and then delivers this NDR message to the original message sender. If the NDR message cannot be successfully delivered, the NDR message is put in the Badmail folder. A .bdr file is the body of the NDR. The Notepad seems to be no longer supported.
