Blocking free mail services

[Richard.Griffin at orst.edu]

We want to be able to block access to Hotmail and other free mail services
on our public PCs and we already have a proxy server loaded for other
purposes.  Does anyone know of any software that would allow us to block
mail without using a proxy server?
