You can't, unless you can find a list of IP's of the servers it uses and block those.

I had a brief look at this.  I use squid to proxy the http traffic so I can see more of what is going on than just the firewall logs.  The messenger client connects to login.live.com to authenticate and then to a server by IP address.  I don't know if it consistently goes to the same IP, so I suggest that you get a sniffer on your machine and run some tests to see where it is connecting to.

If you use a proxy you should be able to block user agent MSN Messenger in HTTP requests, which will block it.
