bounced email


bounced email

An email message that is returned to the sender by the receiving mail server. Called a "non-delivery receipt" (NDR), "non-delivery report" (NDR), "non-delivery notification" (NDN) or "delivery status notification" (DSN), messages are bounced because the recipient does not have an account on that mail server or the recipient's address is misspelled. Email can also be bounced back by either the outgoing or receiving mail server if file attachments exceed a maximum limit. See email and backscatter spam.
