2017-09-11 09:29:57,373 5220 WARNING BB1 odoo.models: mail.message.create() includes unknown fields: email_cc

I am getting this warning and email cc functionality is not working. Can someone suggest should i use different keyword for email cc?? or Is there any other way to add cc service for mail??
