yes, as with PTR, AOL forced a lot of mail servers to get PTR (even in the 
IMail list).  But afaik, yahoo, msn, hotmail, earthlink have not followed 
the leader.

So 1 or 2 years later,  we still cannot wholesale reject because of no PTR.

SPF has two aspects:

1.  AOL's SPF records allows other MXs to fight forgeries of AOL 
senders.  This is what AOL is doing (simple DNS records)

2. The other aspect is AOL's MXs checking other senders DNS for their 
sender domain SPF records (like AOL's MXs check for PTR records). I would 
not be surprised if AOL is not doing this, and won't be for some time, if 
ever.
