You need to:

1. Emulate the lookup on the server using dig

2. Get the proper error message from the exim mainlog when you send

root@***** [~]# ping hotmail.com
ping: unknown host hotmail.com

So that would suggest that your server doesn't have a reverse DNS PTR record for your servers IP address and that it doesn't have any operable DNS resolvers in /etc/resolv.conf
