abstract:In the Internet's standard e-mail protocol SMTP, a bounce message, also called a Non-Delivery Report/Receipt (NDR), a (failed) Delivery Status Notification (DSN) message, a Non-Delivery Notification (NDN) or simply a bounce, is an automated electronic mail message from a mail system informing the sender of another message about a delivery problem. The original message is said to have bounced.
Indeed, one of the little-noticed reasons that Kerry did not get a bigger bounce from the DNC was that day after day and night after night, Republicans got out their message into both national and local media: that he was avoiding a liberal Senate record and is a waffler.
