The problem is actually a bit larger than just yahoo addresses, it seems to be any domain that yahoo actually hosts. It seems the problem is caused by the listserver not sending emails as itself, but instead it sends email as the user that sent the email, but from a different server than the original sender. That is what yahoo servers detect and reject based on my reading of their info at http://postmaster.yahoo.com/errors/postmaster-28.html
