Pink flamingos, of the plastic kitsch lawn-decoration kind and not the real live item, are the official bird of the city of Madison, Wisconsin; the plastic lawn ornament was so designated in response to a lighthearted prank in 1979 wherein students covered the University of Wisconsin’s Bascom Hill with over one thousand of them.
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.
