Can a person successfully subscribe to a listserv list when their From: and Sender: line are slightly different? If so, which flavor shows up in the list? For example, what if my headers looked like: From: [log in to unmask] Sender: [log in to unmask] What would happen? I suspect that once I got subscribed it wouldn't matter since listserv seems to be more forgiving about headers in mail to lists as opposed to mail to the server itself containing commands. ---------------------------------------------------- Bill Verity - 814-865-4758 Fax: 814-863-7049 Postmaster & Listserv maintainer Center for Academic Computing, Penn State University At the office - on my Mac, of course ;-)
