It seems to me after a quick check of the LISTSERV doc on header keywords that a setting of Reply-To= List,Respect is wrong. For example Info-Nets, which seems to be a big problem; I would set it to Reply-To= "[log in to unmask]",Respect Comments? This will at least remind people of where the contribution address really is, although it still doesn't solve the problem of people posting to the BITNET redistribution instead of the Internet contribution address. I'm still thinking about that one. How about this: (1) LISTSERV adds something like: X-LISTSERV: InfoNets (2) LISTSERV checks incoming mail for a header line of X-LISTSERV: InfoNets and if it's present, discards that piece of mail. (3) It might then be (relatively) safe to add [log in to unmask] as a subscriber to INFONETS@BITNIC . Or maybe LISTSERV could add a 'Received: ... by LISTSERV' header line, and check for that, as above? I think some technical solution is necessary because education of users can never be 100%. /Leonard
