HI dave, You are perfectly correct that this is indeed a rDNS issue. If you are host all your own dns then you need to get your hosting company to delegate the IP to your server, if not then you may be able to create the entry in your hosting providers interface.
I hope this helps. But if you require further information, particularly with DJBDNS then please feel free to email.
