I'm checking the imc module and it appears that imc sends all messages with hard-coded content type header so if client sends an application/im-iscomposing+xml message, other clients receives the message with content-type text/plain which is very confusing.

I think the right behavior is to take the content-type header from the original message and use it in the messages imc sends.

Is there a workaround that might help me achieve that?
