For example, if a header line asks for confirmation, the mail agent tells the recipient that s/he has a 'registered letter' from user@host.domain, and would they please sign for it? "Just typing will be fine, thank you." Once it has been delivered (to the user's mailbox), a confirmation is sent to the From:/Sender: address. If the message isn't picked up within a certain period of time (Confirm-Timeout: ?), it is marked as 'unanswered' and returned to the sender. ..Bob -- UUCP: wanginst!ulowell!page Bob Page, U of Lowell CS Dept VOX: +1 617 452 5000 x2976 Lowell MA 01854 USA
