You can try the following, on Linux with IPTABLES:

iptables -A INPUT -j DROP -p tcp --dport 25 -s 209.165.224.0/20
...

In other words, take the first field (cut -f 1 droplist.txt) of every line
and then do an "iptables -A INPUT -j DROP -p tcp --dport 25 -s " plus the
netblock they list.

You can look up the same info for ipchains (if you're still using it) or for
BSD's firewall. You only need to block port 25 from those netblocks, unless
you're really paranoid and want to block any kind of traffic from there (on
Linux w/iptables that would be done by eliminating "--dport 25" and "-p tcp"
from the line, so that *no traffic whatsoever* from those networks can reach
you).
