That is not a complete port list - in the versions of Messenger from 7.5 up - if you are blocking ports, they WILL default to http/https.

If you already allow tcp 80/443 - it will work. That is what makes it so difficult to block in the first place. If you want to block in the future - at layer 4 is not enough, you have to block at layer 7.
