It does nothing to the From: field. Note that with "Reply-To= List" you are also implying "Reply-To= List,Respect". If you don't want LISTSERV to respect the existing Reply-To: header on an incoming posting, the you must explicitly set "Reply-To= List,Ignore". >Therefore, If a "bad" client ignores the "Reply-to:" field, wouldn't it use >the "From:" field, and still send the "out-of-office" message back to the >list? Sure, it uses the From: field, but you haven't changed the From: field. The only way to change the From: field is to change it in your mail client when you post to the list. There is no way to force LISTSERV to rewrite it for you. Nathan
