Along with the previous post, I would be careful with trying to by pass network regulations. I used to work as a network admin and I have had to give severe penalities to people for by-passing regulations (basically at first I made them lax because 99% of the people were trust worthy, when a new employee came in she ruined it all). This resuleted in a 3 day downtime on the network as the T-1 was shut down, the WAN got shut down etc...
Although you may be able to read your email, do you want to be the person resonsible for everyone else's losses?

PS. There is a REALLY easy way to get around it, just use a Proxy. There are lots of free ones floating around, you just need to look for them.
