Gene, I keep a group of people that I can contact whenever I get a duplicate messages complaint. If they aren't receiving dupes then I know that the problem has to be something with the network connections between the listserv and the person receiving dupes...I cordially refer them to their own computer services people and cc the postmaster at their site. I have to say that almost every time the postmaster at the local site was able to trace the problem and satisfy the subscriber. Cordially, 8) Diane dkovacs@kentvm [log in to unmask]
