Jeffrey told Beartooth, | I've never seen that done.
I was once on a list running under MDaemon (which is apparently primarily an MTA with list management as an afterthought). Every three months I got a renewal request that needed to be answered, or my subscription would expire. After my first month or so, the renewal requests were the only mail it sent me; it never had any posts any more. That went on for maybe a year and a half, when the renewal notices stopped coming. I asked the listowner, and he said he had closed the list without telling the remaining members.
