Delivery Errors
Errors may occur at multiple places in mail delivery. A sender may sometimes receive a bounce message from the sender's mail server, and other times from a recipient's mail server. Bounce-back messages from the recipient's mail server are required when a mail server accepted a message that was undeliverable; when a server accepts a message for delivery, it is also accepting the responsibility to deliver a DSN in the event the delivery fails. With the rise in forged spam and e-mail viruses, users now frequently receive erroneous bounce messages sent in response to messages they never actually sent. Modern servers try hard to ascertain that a message can be delivered before they accept it.

Famous quotes containing the words delivery and/or errors:
“There was no speculation so promising, or at the same time so praisworthy, as the United Metropolitan Improved Hot Muffin and Crumpet Baking and Punctual Delivery Company.”
—Charles Dickens (1812–1870)
“There are two equal and opposite errors into which our race can fall about the devils. One is to disbelieve in their existence. The other is to believe, and to feel an excessive and unhealthy interest in them. They themselves are equally pleased by both errors and hail a materialist or a magician with the same delight.”
—C.S. (Clive Staples)
