Message Carbons (XEP-0280) is not sending copy (Openfire 3.10.2)

I am trying to implement carbons feature on my xmpp client, Which consist in the chat for a web app, and a chat for a new window, in a new connection, using a same login.

I am enabling carbons in Those clients in the Following way:

Client sends:

<iq xmlns='jabber:client' from='supervisort1@multisales/beb10458' id='enable1' type='set'><enable xmlns='urn:xmpp:carbons:2'/></iq>

Server sends:

<iq xmlns="jabber:client" type="result" id="enable1" to="supervisort1@multisales/beb10458" />

Message:

<body rid='2463514845' xmlns='http://jabber.org/protocol/httpbind' sid='beb10458'>
     <message to='sac.1@multisales' from='supervisort1@multisales/beb10458' type='chat' id='41' xmlns='jabber:client'>
     <body>Test</body>
     <active xmlns='http://jabber.org/protocol/chatstates'/>
     </message>
</body>

I think the message carbons is enabled, but outhers client don’t receive the message.

Can you help me?

Thanks.

Have these other clients enabled Carbons as well?

Yes. It is enabled in all.

I tested it with Openfire 3.11.0 Alpha (which should be the same as 3.10.2 with regards to Message Carbons, nothing has changed there) and it works as expected. Also tested with BOSH, same result.
