Someone hijacked Nora's email address and sent a bunch of dirty email out in mass. Not to anyone in her address book - simply to a lot of email addresses. We know, because we got about 15 mailer-daemons (spam) back with the subject, and in some cases more info.
So, they did not get into her computer. We have changed passwords. Our McAfee is up to date and current, and a scan shows no infections, etc.
Apparently, they chose her email for some reason as the "from" address. I have communicated with AOL and they assure me there is nothing wrong with her account, and the "sent" folder shows only messages she has sent.
Is there any way that one (or someone) can tell from the Mailer-Daemons and other returns who was the culprit who sent the emails??
I suspect a neighbor down the street as a result of a recent unpleasantness.
