I'm all for protecting copyright-holders and all of that, but YOU'VE GOT TO BE KIDDING ME! This has to be the dumbest school rule EVER! Monitoring university email addresses to check for LINKS? What's wrong with links? The university said it's to protect copyright infringement, but it's obvious what they're doing: looking for another way to make money!
That's right; they're charging people $27.50 per year for the right to do what the Canadian government already allows them to do for free.
Here's the link if you want to read the article: http://boingboing.net/2012/02/20/canadian-universities-sign-bon.html.
Don't try to charge people for things they can get for free somewhere else, unless you can prove that your services are FAR superior to the free option. In the case of inalienable rights, I think these universities are actually breaking the law, which is a whole other level.
But, in general, make sure you can convince people in your marketing endeavors that the services or products you provide are worth paying to receive.
