perhaps qconfirm is what you are looking for: http://smarden.org/qconfirm/ generally you should ignore all mail which sets the Precedence: bulk header. as this is non-standard you should also check for some other stuff explained here: http://www.rfc-editor.org/rfc/rfc3834.txt IMHO, though, concepts like you describe are a bad idea... kind regards Thilo
