We're small shop, but our policy is not to accept email from addresses without PTRs. And we have a long list of pool/dhcp/dyn/resnet PTRs we don't accept mail from as well.
I tried SpamRats a few years ago, but found them to have too many false positives. Then, they were trying to be early detectors of spam orginiating from static IP cable/DSL customers. Good idea, but poorly executed in operation.
