Hello people; A colleague of mine who runs the Sinatra list here has received numerous complaints lately in which postings to the list are being rejected on the basis that they were previously posted even though they were not. Does anyone have any idea about what would cause this and how it can be stopped? I checked the archives for lstown-l and saw nothing relating to this problem there so I guess this is a new issue.
