I have never understood the precived connection between reverse DNS and spam. I have seen some go as far as if the reverse DNS does not match the senders domain they will kick it.
Mostly because a trojaned machine on a broadband connection spewing SPAM will not have a valid reverse DNS entry.
By forcing a policy of accurate reverse DNS, most of the home-broadband- SPAM factories are shut down.
Most ISPs will reject mail if the DNS doesn't reverse correctly, AOL being one of the largest.
