Well, the default msn port is 1863 to block this port use iptables. However msn is port-agile, see: http://www.technicalinfo.net/papers/IMSecurity.html

Most of the messengers talk in html language; so you just got to do a packet log while they try to connect & then after recording those html queries; block them with url_regex filterring with squid or with iptables. (Depends on the way you do the name resolutions)

This way of blocking is actually done prior to the name resolutions. So having this thing in mind; go ahead & do it on your own, its easy.
