What should be XMPP_INTERNAL_MUC_DOMAIN for latest docker JVB version?

Hey guys, I was moving to Docker Jitsi and noticed little difference with the configuration.

I had MUC_JID set as below in my sip-communicator.properties for previous JVB versions:

With Docker, what should be the value of XMPP_INTERNAL_MUC_DOMAIN?
internal.auth.my_domain or internal.my_domain

@damencho / @saghul / @emrah any response here?

Depends on your prosody config.
