Another idea:

Read from which ports have to be opened to what hostnames.

Block the entire IP classes of those hosts for the respective ports (be aware,
a hostname usually point to several IPs).

This is how i managed to allow yahoo messenger (by allowing that traffic).

Don't forget to check from time to time is any of the host has a new IP.
They usually do that relatively often :|

Good luck.
