Fire Fighter Mail Notification

Hi Gurus,

I have an issue with fire fighter....if i am not wrong...When i add a firefighter id to a user id ...it should send a mail...Fore Fighter controller and owner with a link to approve and then they approve the access...then it will send the user access to the user.The above process is not happening with the fire fighter we using..

The fire fighter owner and controller are just getting the logs...Please let me know how to config the initial mail notification.
