    A property of the latest virus_du_jour is that it grabs a domain name and
    sticks on a random user id. For example, it will use something like
    john@redhat.com, fred@redhat.com...and so on.

    There is nothing that you can do about this. It is completely out of your
    control. As Reuben stated the real stupidity results from those misguided
    sysadmins who are bouncing these messages to poor innocent folks
    (sometimes with the virus attached).
