Tell me why I'm getting failure notices when I have not sent an email?


First of all, you CAN get a delivery failure notice for emails which you did not send. More than likely a spammer is sending spam emails to multiple recipients and your email address is used by the spammer as the sender. They don't need access to your email to do it - they can spoof any address they like. The bad news is, you really cannot do anything to stop it. The good news is, it usually goes away after several weeks as the spammer stop spoofing your sender address and move on to others.

Tip

Bounced email


In computer jargon, a bounced <a href="http://www.webopedia.com/TERM/E/e_mail.html">e-mail</a> is one that never arrives in the recipient's inbox and is sent back, or bounced back, to the sender with an error message that indicates to the sender that the e-mail was never successfully transmitted. But what happens when someone sends an e-mail out into cyberspace, and why do e-mails sometimes bounce back?<br /> When a <a href="http://www.webopedia.com/TERM/U/user.html">user</a> attempts to send an e-mail, he is telling his e-mail system to look for the <a href="http://www.webopedia.com/TERM/D/domain.html">domain</a> of the recipient (for example, webopedia.com) and the domain's mail <a href="http://www.webopedia.com/TERM/S/server.html">server</a>. Once the e-mail system makes contact with the recipient's mail server, the mail server looks at the message to determine if it will let the message pass through the server. If the recipient's server has predetermined that it is not accepting e-mails from the sender's address (for example, if it has blocked the address for <a href="http://www.webopedia.com/TERM/S/spam.html">anti-spamming</a> purposes), the server will reject the message and it will subsequently bounce back to the sender. The message will also bounce back to the server if the mail server on the recipient's end is busy and cannot handle the request at that time. When an e-mail is returned to the sender without being accepted by the recipient's mail server, this is called a <a href="http://www.webopedia.com/TERM/H/hard_bounce.html">hard bounce</a>.

Check the validity of the e-mail address. Bell net has no record for that e-mail account.

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

This is an indication that someone is using your e-mail address to spam people, it is called "Spoofing".

Spammers usually use legitimate e-mail addresses to spam lots of people. But some of those e-mail addresses that the spammers trying to spam are invalid. Because they're just guessing it.

Spammers usually gets a legitimate e-mail addresses by hacking the server of some stores. From the server, they could get legitimate e-mail addresses.

People's email addresses are being registered to the store server once you purchase something online. But there's no need to worry because your e-mail address will never compromise.

Here's what you need to do:
1. Access your e-mail.
2. Open the Mailer Daemon (bounced-back message).
3. Click on Submit as Spam button.

The server of your e-mail will try to locate the real sender via the IP address that the spammer's used in sending e-mails. Then the server should trace and block the sender.

But the most effective one is to create a new e-mail account and inform all your friends about your new e-mail address. And try to avoid buying things online.

Good luck and have a great day!
