aol.com		OK

would also work if you did not include the friends in delay checks :)

SORBS is very good, but it's also by nature a non forgiving RBL
as we all know of the half a dozen MX's hotmail have, there are 4 or so 
ip's per MX, and one of the ip's associated with an MX is all it takes to 
upset people and its hard to explain to non techies that thats why when 
you do an rbl test agaisnt mx1.hotmail.com mx2... and so on and it shows 
them nothing that there is a problem. whitelisting it at MTA was best 
solition and its not bene a problem since.

I was asked to do same with yahoo, but all the yahoo stuff *is* spam that 
i've seen, so to hell with them :)
