Set the policy on the chain to DROP and then add ACCEPT rules for the
IPs you want to allow. Example:
iptables -P INPUT DROP
iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A INPUT -s 1.1.1.1 -p tcp -m tcp --dport 25 -j ACCEPT
iptables -A INPUT -s 1.1.1.2 -p tcp -m tcp --dport 25 -j ACCEPT
...
You get the idea.
