I've gotten a couple of these emails this week purporting to be from university webmasters. They come from gawab.com which seems, according to a few webforums, to be home of lots of spammers. Universities use the .edu domain, not the .com domain and have no reason to change domains.
Dear Webmaster of http://www.southalabama.edu , I´m the webmaster of indiana.edu and and I want to inform you about the changing of our domain name. Old name: http://www.indiana.edu New name: http://indiana-edu.com
