If you're talking about how an individual client handles this, that's strictly up to the client. LISTSERV can send a "Reply-To:" header till the cows come home, but if the client doesn't recognize it and uses the "From:", "Sender:", or even the RFC821 MAIL FROM: as the reply address, there's not much LISTSERV can do about that. I thought the complaint was that LISTSERV wasn't setting the Reply-To: header correctly to begin with, which you can test by simply looking at the list's archives. I <know> <that> works properly. You might want to try IETFHDR in these cases where it doesn't seem to work on a given client. Nathan
