Receiving a ton of emails titled "Undelivered Mail Returned to Sender". Have I been hacked?

[jungleexplorer]

Well, woke up this morning to find my inbox packed with hundreds of emails titled "Undelivered Mail Returned to Sender". The headers say they were sent from my email address and most of the emails were about women trying to find love. They had an "EML" attached file as well. So, either my computer has been hacked, my webmail account has been hacked, or my email address has been targeted for a spoofing spam email campaign. So I have changed my webmail log in password and I am running a full system scan on my system with Norton 2014. This is most likely as spoofing thing and I am wondering what I can do (probably nothing. I know!)? The address that is being attacked (I have many) is my most important address. I really don't want it to get blacklist. Is there anything I can do?

Yes you have been hacked. Contact the email provider and notify them so that they can detect where the hack came from.

your email account was likely hacked.
-change your password to something more secure
-notify your contacts that they may have received spam.

thats all you can really do on your end. you could contact your email provider as suggested above and they may be able to do something or they may not.

Talked with my webmail service and they confirmed that my email address has not been hacked, it is has been spoofed. They have identified the IP address of the sender as someone other then me. Thanks for the help guys.

You don't have to be hacked. Most probably, your e-mail address was lifted from somewhere, and used as sender e-mail for spam from somewhere. That's why it's you getting NDRs.
