My school is rolling out (heavily monitored) student email. All inbound and outbound messages are screened by humans at our IT dept. We're also responsible for what we receive, which is completely wrong because that's beyond my control, and I can't delete anything before it goes through the gateway.
As a result of this, they're blocking all external webmail (at least the ones they can find, but if you visit a new site they don't approve of but they haven't found yet, it's blocked within minutes).
My question is what addresses does the iGoogle Gmail gadget request (excluding images in HTML email, obviously). I'm not looking to start a flamewar on the ethics of circumventing filters; to be fair, our IT department is brutal and relentless and even block sites that are useful for research.
