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.
