But I'm on Campus!

That's right, blocking spammers should not affect you at all if your machine is on the UIC campus network. So what's up?

We determine whehter a machine is on campus by checking your registration in the DNS (Domain Name Server). If the DNS says you are in the uic.edu domain, that counts as on campus. If, despite Internet regulations and campus policies, you are somehow using a computer that is not registered in the DNS, it will appear to be off-campus for this purpose. You can the machine you are using now:

If you need to get registered, ask your department's REACH representative. If you can't find your REACH rep, send a note to network@uic.edu.
