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)
“Let us pardon him his hope of a vain apocalypse, and of a second coming in great triumph upon the clouds of heaven. Perhaps these were the errors of others rather than his own; and if it be true that he himself shared the general illusion, what matters it, since his dream rendered him strong against death, and sustained him in a struggle to which he might otherwise have been unequal?”
—Ernest Renan (1823–1892)
