Nesting mail attachments annoyance

Despite all my efforts to thwart their practices, some people forward me mail that has been forwarded many times. (Usually from AOL-ers) When opening it with Outlook Express (yeah, I know this is an XP forum) the mail shows up nested as attachments within attachments, sort of like http://russian-crafts.com/nest/history/first.jpg . I usually delete these messages without reading them, but sometimes I like to read them. It is impossible to train some newbies to correct their e-mail e-tiquette. My question is, why does OE nest the mail, while other mail clients list them as one long e-mail. More important, is there a work around?
