Auto-Reply does not work

I have som issues with the booking calander.

– The autoreply does not work and it is enable. I have also checked the spam. When a booking is made, the person that booked are not receiving any email.

– I am not receiving any emails to my mail when a person sends a booking request. I have to always go in to the admin to check if there are any pending requests.

– Is it possible to send a automatically e-mail to the person when a booking has been accepted and confirmed.

– Is it possible for the client to cancel the booking from the booking confirmation that has been send?
