Rejection notices should contain the text of the rejected mail. If I get a piece of mail saying "Your mail could not be delivered because (...)" and nothing else, I'm not really informed about what has happened. I want to know WHICH piece of mail was not delivered. If you include a copy of the original mail in the rejection notice LISTSERV will recognize it as such, and that's all. Now a question: let's assume that I change the Sender: field to point to the moderator. You'll get an ERIC MAIL in your reader whenever someone mails to LSTSRV-L. If I had set it to Reply-To= Sender, you would not even know that this came from LSTSRV-L. MAILBOOK would think it came from me, and would log it in the notebook associated with [log in to unmask] You will have no way to know what comes from *me* and what comes from a list of which I am the moderator, unless you looked at it closely. This means you couldn't read "important" mail in the morning when you arrive at work, and keep distribution lists mail for later on. I doubt more than 10% of people would want that. And those who want are those who work with a poor mail user agent which doesn't allow them to make any useful use of the contents of the Sender: field. Now if the next day I move you to another server, you're going to get some MEYER MAIL or EARNMAIN MAIL instead of ERIC MAIL. Still for the very same distribution list. Eric
