For MSN I've successfully used these three rules:
iptables -A FORWARD -p tcp --dport 1863 -j DROP
iptables -A FORWARD -d 207.46.110.0/25 -j DROP
iptables -A FORWARD -d 207.46.104.20 -j DROP
For Yahoo IM, you need to block access to ALL servers. The list below
is probably no longer complete, if it ever was, but:
/sbin/iptables -A FORWARD -d 63.216.136.22 -j DROP
