Not quite.  If you do not whitelist AOL, you'll get fewer messages from 
them.  The "common pool" note beside the AOL entries indicates that AOL 
uses SMTP server pools for retries.  The retry is not sent from the same 
SMTP server as the original try was sent from.  Without AOL on your 
whitelist, greylisting will cause AOL to eventually give up trying to send 
the message because greylisting expects ip address to be the same on retries.
