Messenger will also use port 80. You'll need to do l7-filter for that. Or using squid, setup acls for the messenger mimetype which will catch it if it's coming through port 80, and then also block port 1863.
I believe that's been covered before in this group so you may want to search the archives. Sorry, but I don't have the exact details in front of me. Thomas J.
