I am trying to find how long Listserv can keep track of postings to prevent duplicate posts from being distributed. I looked through the archives at UGA and I am not finding it. I have had a complaint that a posting was improperly rejected by Listserv. The duplicate (listserv claims) arrived 7 hrs after an other copy was posted (maybe 50 messages between the two messages). How long or how many messages can Listserv keep track of?
