8.2.1 Transmission of Messages

You can proceed sending operation for mail/news messages while you are off-line, then it will be reserved for sending (if you are using `im-wl.el', it is irrelevant). Messages reserved for sending while off-line are accumulated in the queue folder, `+queue'. These messages are transmitted at once when Wanderlust becomes on-line.

You can visit `+queue' in the off-line state and confirm content of messages in the queue. You can also remove messages. Removed messages are not transmitted even in the on-line state.
