I've got a server with several ip's on eth0. I want to block all traffic

eth0:2 is www.xxx.yyy.hhh
I've tried
-A RH-Firewall-1-INPUT -p tcp -d www.xxx.yyy.ggg --dport ! 80 -j DROP
-A RH-Firewall-1-INPUT -p tcp -d www.xxx.yyy.hhh --dport ! 80 -j DROP
and restarted (and several variants of this). iptables-save displays
*filter

:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [769:48207]
:RH-Firewall-1-INPUT - [0:0]
-A INPUT -j RH-Firewall-1-INPUT
-A FORWARD -j RH-Firewall-1-INPUT

-A RH-Firewall-1-INPUT -d www.xxx.yyy.hhh -p tcp -m tcp ! --dport 80 -j DROP
-A RH-Firewall-1-INPUT -p icmp -m icmp --icmp-type any -j ACCEPT

and I notice it puts the ! in front of the --dport, but has no complaints.
However, I can telnet to www.xxx.yyy.hhh 443. What's wrong with the rules?
