A BDP - Exchange Diagnostic Message is a diagnostic file that is created by MS Exchange. This occurs when there is a problem delivering an email message. One of the reasons for an issue when delivering an email message is that the local .EML file contains a report that houses files that weren't delivered, or NDR. BDP files are, in turn, stored in the a folder designated for undeliverable mail (Badmail).
