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
can't send usual plain-text message on channel 4. TLV(0x03) and TLV(0x06)
is optional.
