The message goes on to ask you to login to your e-mail account to ensure your account information is up to date, due to an upgrade to an "advanced server" to prevent spam from reaching your inbox. A link is provided, with a URL that has mit.edu included in it. This message is not from MIT!
Many members of the MIT community are aware that such messages are fraudulent and will ignore them. But it is important to spread the word to those who may fall for such messages. If a user clicks the link, his or her username and e-mail password could be compromised. Within minutes, the hackers will be able to login to the user's e-mail account and use it to send out the spam they claim in their message they are trying to prevent.
