Why is Mail Delivery System resend messages that I never sent to people, I don't know?

My Inbox has more than 15 messages from mail delivery system resend messages for me to people I've never heard.
I think this one is disturbing:
We were unable to send your message to [email protected]
I didn't send anyone to the address indicated in the message

Probably not be overly concerned. Sounds like a spammer used your email from: address to send spam messages, and now those which could not be delivered back to you. It is called backscatter.

She stops at a given time. Until then, you can create a filter to remove immediately.
