A bounce message is a form of auto-response sent to the sender of an email when the email cannot be delivered to the intended recipient. Although informally referred to as a bounce message, the message is technically known as a Non-Delivery Report (NDR). The message typically contains the date and time the original email was bounced, the identity of the mail server it bounced at, the reason for the bounce (e.g. mailbox full, user unknown, etc.), the headers of the bounced message, and a full or partial reprint of the original bounced message.
