You can do that on different places... on your edge router, assuming its a
cisco:

ip route 66.249.96.0 255.255.240.0 null0

Or simply in iptables something like:

-A ETH0-INPUT -s 66.249.96.0/20 -p tcp -i eth0 --dport 25 -j REJECT

Like that.

A nullroute on the network edge is most of the time easiest ...

Bye,
Raymond.
