Hi Welcome
The reason why you received a Mailer Daemon Notice is because the e-mail address may no longer be valid, or there may be a problem routing the message to the appropriate mail server

If you didn't send any of those emails, you might have spyware or a virus infecting your computer. Run a virus scan if you have anti-virus software installed, and hopefully it will find and remove the infection. If you don't have anti-virus software, you should definitely download and install a program. Avast and AVG both offer free anti-virus scanners. If you have the Yahoo! Toolbar, you can run CA Yahoo! Anti-Spy directly from the toolbar, which should be able to detect most spyware and some viruses.

The server could of been down. If the email address is correct try again at a later time

Open a new email account elsewhere, such as on Google's FREE Gmail.com send your message from that new account.

When you get mail from a "MAILER-DAEMON" or a "Mail Delivery Subsystem," with a subject similar to "Failed Delivery," this means that a message which you sent was undeliverable and has been "bounced" back to you. These messages are produced automatically and usually include a reason for the delivery failure. Bounced messages normally consist of two parts. The first contains the reason for the bounce; the second contains your original message.
The most common reason for a failed delivery is that the email address you entered is not valid. If the Mailer Daemon says that the account does not exist, double-check the spelling of the address you entered. A single mis-placed letter can be enough to cause a failed delivery. If the message continues to be bounced back to you, you may want to verify that the account has not been closed or moved.
If there is a different reason given and you would like us to investigate it, If you can copy and paste the reason given for the failed delivery into the message you send us, it will be very helpful as we attempt to determine why your message bounced.

the address to wich you are try to send email that address is wrong so you check the receipients address because of this you get failuer notice from yahoo....
check your each contacts ...

I think there's no other way except contacting your yahoo support. In free email, no important setting you can set.
