Of course, usual logic applies there. If you set up a subdomain, make sure there's an MX for it, make sure it answers, make sure it's got an answered abuse box. Make sure your info really IS opt-in (as a college I don't imagine you're a big spammer, but I need to mention it anyway). Make sure CYA has done with regard to sale or alternate use of your intellectual property. > The second alternative may be better from a reputation > perspective.
