Packet filtering is implemtend in 'ip firewall filter', 'ip firewall filter' does not include special matchers for MSN or Yahoo traffic. Most probably you need to block by protocol/port.

MSN Messenger uses TCP ports 1863 and 5190


add chain=forward protocol=tcp dst-port=1863 action=drop comment="MSN Messenger" \
disabled=no


add chain=forward protocol=tcp dst-port=5190 action=drop comment="MSN Messenger" \
disabled=no

If your trying to block MSN Messenger Live you might want to try the following ports: 6901& 6891-6900

When you block port 1863, msn will use connection over HTTP
In logs it looks like
1170741586.866 1049 195.X.X.X TCP_MISS/200 433 POST http://207.46.107.35/gateway/gateway.dl ... 3619.XXXXX - DIRECT/207.46.107.35 application/x-msn-m

So you have to do ACL on proxy also, to close let's say /gateway/gateway.dll

This is what i did, based on a couple of posts in the forums:
14 X ;;; MSN Messenger
     chain=forward protocol=tcp dst-port=1863 action=drop

15 X ;;; MSN Messenger
     chain=forward dst-address=207.46.110.0/24 protocol=tcp action=drop

16 X ;;; MSN Messenger
     chain=forward protocol=tcp dst-port=5190 action=drop

17 X ;;; MSN Messenger
     chain=forward protocol=tcp dst-port=6901 action=drop

18 X ;;; MSN Messenger
     chain=forward protocol=tcp dst-port=6891-6900 action=drop
Worked for me so far.
Regards!
