Really? Because I have found that many of these messengers now use port 80
or scan for another open port when the default port is blocked. I used to
have them all blocked at our firewall until they started using 80 and
scanning for other ports. If you're blocking them successfully....is there
somehow you could find it in your heart to let me know which ports you are
blocking exactly? That would be greatly appreciated!!
