I'm trying to think of ways to stop the bounce mail from stupid mail systems to the list I run. I think this will do it but I'm not sure and wanted to run it past you. If I change the SEND=PUBLIC to SEND=PRIVATE that should stop listserv from distributing mail from persons not subscribed to the list, right? Since mailers don't normally subscribe to lists they wouldn't be able to bounce crap back to the whole list. Will this work? Is it that simple? Are there any complications for legitimate subscribers that you forsee? =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Tom Cervenka - Univ of Il at Chicago, Info Cntr, Phone 6-7739 Internet: ctct100icvmc.aiss.uiuc.edu
