    Hello:
    First, please excuse me for just popping in like this.

    Can anyone here tell me if it is possible (and/or realistic) when a
    person receives forwarded information via an email, then simply
    forwards that information to another person, who forwards... yadda
    yadda yadda...

    for there to be an "IP Trail" of all of those who receive/forward that
    information that can be identified and used to spam any or all of those
    in the trail?

    Thanks.
    William

    That's one of the reasons that spam is always labelled "forward this urgent
    message to everyone you know"
    Every forwarder's address is added to the email source
    If the original creator wrote the mail to find an image on their server when
    the mail is opened, they can extract a lot of information from each
    receiver.

  3. Depends on wether the mail was forwarded using the forward-button
    (which creates a new mail with just the text attached) or by creating a
    new mail with the complete old mail attached (with all the headers).

    In some mail clients, the From-information of the forwarded mail will
    be included even in the former case, though - so the final recipient
    might be able to harvest email adresses from the complete mail body.

  4. How, if the message isn't sent back to the spammer?
    Nope, that's not how it works.

    The image has a special name that allows the spammer to verify that the
    recipient has seen the mail - but if that mail is forwarded, the link
    to the picture remains the same, so the spammer would only see multiple
    hits to the same image, which would still only tell him that the
    original mail address was valid.
