I try to secure my ejabberd by configuring openssl ciphers like this for s2s communication:
{s2s_use_starttls, required}.
{s2s_certfile, "/etc/ejabberd/mycert.pem"}.
{s2s_protocol_options, ["no_sslv3", "no_sslv2"]}.
{s2s_ciphers, "HIGH" }.
However the test shows the server still serves RC4 and sslv3. Why do these settings not show any effect?
