    AFAIK, I think that the only way to block web-based e-mail would be
    through a proxy or host file, as to block it through a firewall, one
    would have to block port 80, used for all web viewing, which isn't
    very practical. For MSN and Yahoo chat, you'd have to find the ports
    for which they are typically used and block them (I don't know them
    off the top of my head), and prevent users from installing said
    applications.

    Good luck, and I hope this was helpful.
