Receiving message server by another subscriber by subscription from Openfire server

Dear developers, there is a question.
There is an openfire server, with connected clients (each has its own jid).
There is a client A with a roster list, which receives subscriptions from client B, C.
We start a new client D, who receives a subscription from the client C.
Whether it is possible so to make, that client D, received all message which come from client C.
So far it is not possible to do so through subscriptions (installed in the roster and from, to, both - nothing).
Maybe somehow still possible?
