Unless it blocks or filters *all* access (WebSense for example), you might try tunnelling out via ssh. This assumes you've got a reachable host somewhere outside the firewall that is running sshd and has port forwarding enabled.
I use this setup myself, and forward all traffic (pop, smtp, IM, web proxy) through the ssh tunnel. I run the ssh daemon on a non-standard port, and have had very good luck getting out through firewalls that block common ports.
