AOL requires a reverse DNS, I can't imagine anyone legit wouldn't have reverse DNS just because of this. See http://postmaster.info.aol.com/errors/421dnsnr.html

We tried to institute it a couple of weeks back.  It appears that the Spammers have learned to setup their DNS correctly.  We got more reverse DNS failures on legitimate mail than we did with spam.  We are finding the same holds true for SPF as well.

Are most people doing a reverse DNS check now on incoming email?
