This was happening to my list, too, but I think I found the source of the problem (at least for my list). WMST-L has two subscribers from SAUNIX.SAU.EDU, wherever that is (I couldn't find it), and it appears that the SAUNIX mail system is/was malfunctioning. Messages sent from WMST-L to those subscribers would be sent back to the list; the LISTSERV software recognized the message as one that had already appeared and so sent a message back to the original poster "rejecting" the message as a duplicate. Most posters didn't understand what had happened, and so they sent the message yet AGAIN to WMST-L, sometimes changing enough so that it got posted again. Sigh. Anyway, I solved the problem temporarily by setting the two SAUNIX.SAU.EDU subscribers to NOMAIL. I tried contacting the postmaster there, but my message was returned with the explanation that the postmaster was "user unknown." I then tried writing to the two subscribers; a day or so has gone by, but I haven't yet heard from either of them. I'm not sure whether your problems have the same origin, but I thought you might find the above explanation useful. Joan Korenman, WMST-L Listowner KORENMAN@UMBC Univ. of MD.
