You'll receive this snac when another client send you a message on channel 4
thru server. ICQ clients use this snac to send messages to an old/offline/invisible
clients if message type != 1 or message flags != 0 (for example plain-text
multi-recipient message to an offline client) but this doesn't mean that you
will never receive usual channel 4 plain-text message. See also
