Assuming your domain isn't already in some list someplace on the internet you might be able to keep people from successfullly getting a reverse IP match on your domain by ensuring that your PTR record does NOT match your A record. If you have control of your DNS you should be able to change this on your own, otherwise it might be difficult.
I'm not 100% positive if this will prevent a reverse lookup, however I know that in order to send e-mail to certain hosts (AOL for instance) you need to have your PTR record match your A record so that AOL can do a reverse lookup before delivering your e-mail to one of it's subscribers.
