Linux: Iptables # 17 Allow secure POP3S incoming request?

Secure POP3S uses the tcp port 995 by default. Following iptable rules will allow server POP3S incoming client request (open port 995) for server ip address 202.54.1.20:
iptables -A INPUT -p tcp -s 0/0 --sport 1024:65535 -d 202.54.1.20 --dport 995 -m state --state NEW,ESTABLISHED -j ACCEPT

iptables -A OUTPUT -p tcp -s 202.54.1.20 --sport 995 -d 0/0 --dport 1024:65535 -m state --state ESTABLISHED -j ACCEPT

Following rules allows POP3S outgoing client request from firewall host 202.54.1.21 (open port 995):
iptables -A OUTPUT -p tcp -s 202.54.1.21 --sport 1024:65535 -d 0/0 --dport 995 -m state --state NEW,ESTABLISHED -j ACCEPT

iptables -A INPUT -p tcp -s 0/0 --sport 995 -d 202.54.1.21 --dport 1024:65535 -m state --state ESTABLISHED -j ACCEPT
