What is a .BDR file?

A .BDR file is a type of file known as a Publisher Borders File. It is mainly used to store information about emails that couldn't be delivered. When an email fails to reach its destination, a report called a non-delivery report (NDR) is created. This report is saved as a .BDR file. It includes important details such as why the email wasn't delivered, an error code that explains the problem, who sent the email, and who was supposed to receive it.

To open a .BDR file, you would typically use Microsoft Exchange Server. This is a program that manages emails, calendars, and tasks for businesses. It helps in handling emails that couldn't be sent properly by storing them in a special folder called the Badmail folder. Alongside .BDR files, you might also find .BAD and .BDP files in this folder. These files are related and help in managing emails that encountered delivery problems.
