I am assuming the majority of the machines in this case are Windows boxes. Your best bet would be to simply block these applications by modifying the hosts file, and blocking the webmail sites and the msn/yahoo chat sites as well.

Hope this helps

I am very new to the firewall and network security world. I have a situation wherein I need to block webbased email access and the ability to upload attachments to web-based email. I also need to ensure that MSN/yahoo chat is disabled and quotas are established for web surfing.

Is there an Open Source solution to this problem. The network comprises Cisco Routers and 500 series firewalls.
