What looks like a mail file to me was sent to one of our lists. It arrived as a CLASS M punch file and was called TANDERSO @THUMAIL. I've included the first part of it below. Our normal software would consider this a mail file since it is class M. However listserv treated it as a file and rejected it since the list won't accept files. What's wrong?
