DSN (“Delivery Service Notification” or “bounce” message)
DSN (aka “Delivery Service Notification” or “bounce” message)
Once a mail server has accepted a message for delivery and cannot deliver the message to its final destination, it MUST generate a non-delivery report DSN to notify the sender that the message could not be delivered.
This can cause problems when a mail server accepts forged messages – see also backscatter.
