Mohan, AFAIK, you can deny outgoing connection by its TCP/UDP port number.
Here is how you specify the simple firewall rule
----------------------------------------- Rule SrcIP Srcport DstIP DstPort Action -----------------------------------------
Blocking MSN by blocking port 1863 for outgoing connections iptables -A FORWARD -p TCP --dport 1863 -j REJECT
Blocking MSN by IPaddress pool for outgoing connections
iptables -A FORWARD -d 64.4.13.0/24 -j REJECT
I hope you get the idea.....
See this list of Famous Application which you would consider to block
