Are reverse lookup files compulsary ??

[Marc Storck]

Reverse DNS is used to resolve IP addresses to names, a reverse DNS file 
for your domains does not exist because reverse DNS isn't just the reverse 
of your domains!! The reverse DNS for your IP address(es) is delegated to 
the company from where you get your hosting from, or even their provider.....

And for the next time use a real -mail-address.... so we can reply to you 
directly!!! And perhaps you should by the book DNS & BIND 4th Edition from 
O'Reilly!!
