Absolutely,
WHITELIST REVDNS
.declude.com
You can also can create your own RDNSBL zone in your
DNS server (that's what I did) and create one for SPF domains that spammers set
up to reliably reject mail based on reverse DNS (thank you for them adhering to
SPF!).
Then
you set up a WhiteList zone for known "good" reverse DNS, which you use to
subtract weight or combine with a filter to whitelist
outright.
