It is just a message sent by an email server. Whenever it fails to deliver any email to a particular receipts, then it sent an email in the form of " Mailer-Daemon ". That mail gives you the idea that the following mail is undelivered to a particular receipts.

A daemon is a program that works behind the scenes on a server, doing useful things.

A bounce message, or (failed) Delivery Status Notification (DSN) message, alias Non-Delivery Report/Receipt (NDR), 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.


In other worrds you ca say that an errors can 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. That happens because when a server accepts a message for delivery, at the same time it takes the burden to send a DSN in case 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. Sometimes they type in the wrong receiver's username and they get an e-mail from that, too.

Software in a mail server that delivers messages to recipients. When you get a [email protected] message in your inbox, the server at that company is informing you that it is returning your message because of some failure. The "to" e-mail address may no longer be valid, or there may be a problem routing the message to the appropriate mail server. Your domain name may be on a blacklist, and the server is refusing all incoming messages from it.
