The way to specify the content type of emails is using the  
'content_type' accessor within your "create" method:

   def confirm(reservation)
     content_type "text/html"
     ...
   end

   ...
   ReservationMailer.deliver_confirm(reservation)

Unfortunately, documentation for ActionMailer is still sadly lacking,  
and I apologize for that. I'll do something about that soon.
