Not according to the documentation at the referenced URL:

spammer at aol.com			REJECT
cyberspammer.com		REJECT
TLD				REJECT
192.168.212			REJECT
IPv6:2002:c0a8:02c7		RELAY
IPv6:2002:c0a8:51d2::23f4	REJECT

would refuse mail from spammer at aol.com, any user from cyberspammer.com (or any host within the cyberspammer.com domain), any host in the entire top level domain TLD, 192.168.212.* network, and the IPv6 address 2002:c0a8:51d2::23f4. It would allow relay for the IPv6 network 2002:c0a8:02c7::/48.


bets regards,

Steve
