Information about the .bdr (bdr) file type

This is one of two possibilities that we have on file for the .bdr file extension, follow this link to view both possibilities.

Below is all the information we have available on file about the .bdr (bdr) file type.

Bad mail report file. A .bdr file is a text file that contains a report on the reason for the non delivery of a message (i.e. typically the reason why the mail is held in the Badmail folder). It can be opened using notepad (or any text editor). It contains the body of the NDR, the error code, message sender and mail recipient information. cf .bad for more information.

If the .bdr file is located in a folder called "Badmail" then see .bad for further information.

Where this is available we would like to include file format information on .bdr files, as well as information on how to view or open files of type .bdr. If you know of any information which we have missed then please let us know.
