What is this strange message from OIT at the top of the email that I just recieved?

Email Phishing Warning


 

Many of the phishing attacks that we see
on campus continue to use the same hosting sites to house their online forms over and over again - the web sites that they are trying to get people to visit, so that the attacker can con the person into giving away their credentials. We have setup a warning system that checks for these commonly-used URLs and, when it finds a match, the system appends a warning text to the beginning of the email, warning the recipient that the message is probably a phishing attack.
 
We encourage all of you to remain vigilant and to maintain a healthy dose of skepticism about the Internet. Be careful out there!
 
Here's the text that we are using in the
aforementioned warnings:
