Does openfire 3.10.2 support XEP-0191? How to block a contact?

I am developing chat application in android and using openfire xmpp server? I am trying to block the user using XEP-0191: Blocking Command but getting error in result.

D/xmppConnectionService(24373): block result type ERROR result string:

I also tried with the another protocol XEP-0016: Privacy Lists but not succeed. Getting the result from server but blocked user able to send the message.

If anyone have idea. please reply.

Thanks in advance… @
