Two interesting behaviors in 1.8b: First, we have several nested lists. LISTSERV is now generating a Received: and Return-Path: header for every level of the list causing an explosive jump in the length of mail headers. Second, LISTSERV has taken it upon itself to determine what constitues a "SPAM" and disables the offending userid for 48 hours. I have had several complaints from our users about the above changes. My question how can I turn these 'enhancements' off? If I can't then I'm dropping back to 1.8a. Maynard
