Doesn't use SPF?

Maybe you just meant they are not adding any headers to their inbound 
mail stating whether or not you passed an SPF check? There is nothing 
that requires anything be added to headers for SPF.

Working for $MAJOR_ISP (measured in millions of messages processed each 
day), we have not received a significant number of complaints about 
undeliverable mail to AOL. I am intimately familiar with AOLs mail 
blocking policies, having been on the wrong end of them several times, 
and I have not heard through any channels of excessive failures.
