    I've noticed that they *ALL* have their From:, To:, and Subject: written in
    uppercase. So it's really easy to filter them out depending on the tools used.
    If a mail header either matches ^FROM:, ^TO: or ^SUBJECT: then it has high
    chances to be a spam/virus. I checked all my recent mails and a few months
    back in LKML and did not found anything except spam/viruses which match this.
    At least, we should be lucky that these virus writers don't fully respect
    protocols...

    HTH,
