Feckin' spam!

My spam filter keeps catching bounce emails telling me messages I haven't sent cannot be delivered.
The email address that the spam that's bounced was supposeldy sent from is [some random string of letters]@richardwinskill.co.uk.
What I want to know is, are these addresses being used to spam people, and failing, or are the bolunce messages themselves the spam directed at me to try an trick me into responding to the "original" message or replying saying, "What the hell," and thus demonstrating that my address is real so they can commence spamming in full?

  1. I don't know the answer to your question, but I've got the same thing happening to me at the moment and I've reported it to my ISP (which has just completely ignored me as far as I can tell). It happened to me once before, I reported it, my ISP said they couldn't do anything about it, but it stopped a few weeks later.

    Probably both But I think at the moment they are mainly spam messages posing as bounces. You can often tell by the from address of the bounce message, the return address should be to prevent bounces bouncing.
    Its because of these sorts of messages that I had to change my mail configuration so my server now rejects all unknown email names, one advantage of running your own mail server, you can block spam at an earlier stage.

  3. You were right the first time, a spammer is forging your address (or addresses from your domain) to send people spam. Some of these people are bouncing back the spams in the mistaken belief that a) it will convince the spammer their address doesn't exist, and he will then remove the address from his list (as if), and b) that the spam actually came from the address on it. http://en.wikipedia.org/wiki/Joe_job

    This is why you should never bounce spam back to the sender, it's almost never going to be from who it says it's from. All it does is inundate the domain owner with rubbish.
