I'm sorry, apparently I wasn't very clear with yesterday's posting about our recent problems. Here's the sequence of events: 1. A subscriber posts to the list. 2. Subscriber receives confirmation from listserv that posting has been processed and sent. 3. Posting is sent to the list. People *do* receive it. 4. Original poster receives message from our listserv saying the posting has been rejected because it is a duplicate posting. The message saying the posting is rejected shows it has gone through a mailer at ccmail.wiu.bgu.edu. We have been in touch with the acting postmaster to no avail. (The regular postmaster is on vacation.) Any guesses on the problem? We have set all users at that site to nomail and the problem has gone away, but since it is not the fault of those users, I'd like suggestions for a solution. ---Tim
