Secure XMPP on CentOS

Hello all, I have a problem with my XMPP server at security tests result that sslv3 must be disabled and RC4 also weak ciphers on 112 and 128 bits...

OS: CentOS
XMPP platform: ejabberd 2.1.13

Security test result

https://xmpp.net/result.php?domain=hackyard.net&type=client

ejabberd use openssl and I really don't know how to disable sslv3 tlsv1 rc4 and weak ciphers..

I do not have nothing in ejabberd.cfg regarding this.. and I would like somehow to secure my server.
