Mail delivery failure notices

Answered

Hello, I have been receiving hundreds of emails per minute from 'Mail delivery System' advising of email delivery errors.  What is going on? Please help.

Re: Mail delivery failure notices

Sounds very much like your email address has been hacked or what is known as Spoofed. It would appear that emails have probably been sent out with your email address.

Spammers frequently spoof the From sender on the email they send. They just substitute their real email address with a random email address found on a mailing list or one just randomly made up. Some poorly configured email gateway products don't distinguish between the manually editable "From" address and the actual sender origin, so they simply send any undeliverable messages to the spoofed From address.

 

First thing I would be doing is changing my email password, but if at all possible change both you email address and password.

 

This might only last for a day, could end up a week might go on for a month, it's hard to say.

Hey Tankbuster,

 

I think DEANJA has gotten most of the issue covered! The only thing I would suggest is check your email settings. Sometimes when this happens and the email has been compromised, forwarding settings can be made in the email itself. If you pop into Webmail, you can check over the internal settings.

Thanks very much, managed to change my password.  Email address has to stay the same though.  Emails still coming.

Re: Mail delivery failure notices

I am having the same problem and have to keep my present email address. It makes me feel somewhat vulnerable to know someone is using my email address without my knowledge.

 

Any further advice would be appreciated

Thank you

Hi Danara,

 

The posts by Deanja and Brodie pretty much covers it off. 

 

Have you performed the steps they suggested?
