I knew this was going to happen. As noted before, a message was sent using an outdated list with the LIST name in the “reply to” field. I use Thunderbird, which shows this field, but my informants tell me that Exchange does not show it by default, which may explain part of the problem. Complaints about not belonging on the list go to the whole list, then complaints about getting the complaints go to the whole list. A wise head (an econ prof) sends to the list telling people to stop sending to the list, to direct concerns to the original sender (whom he names) but people don’t get the message. After four days, the original sender sends a note to the whole list (once again with the LIST in the “reply to” field!!) telling people to contact her directly if they want off the list and giving her email in the text body. More people hit “reply” to say they want off the list, and then more people hit reply to complain about getting all the replies. Then a guy announces to the list that he is tired of getting all the messages, so HE is going to reply to the list to complain every time anybody else sends to the list!! He persists in arguing that this is a good plan even after I send him a private message telling him why this will do no good. Several other people adopt the practice of hitting reply to echo his complaint every time he complains. At this point, about 20 messages an hour are being sent to the list, with no end in sight. The original sender is not on the list.
