Reverse DNS seems to be possible - http://btbusiness.custhelp.com/app/answers/detail/c/1995,2003,2946,2997/a_id/8763
Don't know if you need to have the domain with them though or they can do it for all business customers. If you find out, can you post back as I'm interested in having it set up sometime in the future.
TTFN

Reverse DNS is possible, you don't need to have the domain with BT - if you go to reverse DNS this explains how to get this setup
