Depends on your exim and patches;

on mine:
    host_accept_relay = localhost : 192.168.0.0/16 : [2001:470:1f00:368::]/64 :
*.aol.com


or on others:
    host_accept_relay = localhost : 192.168.0.* : 2001::470::1f00::368::::0/64 :
*.aol.com


And, note, this is for people who receive on YOUR network, and send FROM your
network. So, unless you're setting up an AOL exchanger, do NOT put *.aol.com
in your config, rather, put *.nepasolutions.com or somesuch instead.
