Like just about everyone else in the known universe, your e-mail address is being spoofed to send out spam, and when the spam hits a non-existant mailbox, YOU are getting the bounce-back error.

Nothing you can do except tune up your spam filter to delete these as the come in.  I get literally hundreds of them every day.

Okay, thanks Brian. That’s what I wondered. I’ve told my spam blocker to throw the return messages in the trash. But still. That’s my address, darn it.

Yup, what Brian said. I get hit with these on my various domain names occasionally, and all you can do is weather the storm.

Ditto.

I was outraged the first time this happened to me, particulalry since they were brazen enough to send them to one of my other email accounts using that return address.

My ISP said there was nothing they could do, that they weren’t coming from either of my accounts.

Still irritated me that someone could steal my name and use it that way.
