Keith, it seems to me the crux of the issue is really with the listserv itself. I'm sure folks post to other lists (Yahoo, Google, etc.) using a wide range of email clients, yet I've never seen the same issues with those services. I would guess those other services automatically translate the encoding to UTF8 or some other standardized encoding prior to distributing the messages. Would it be possible for the list owners (I know that's you for EvFit, but I'm not sure about this list) to contact ICORS and see if there's a setting that could be changed, or possibly some other solution?
