For the good of the group, below is the phishing email that we've been
seeing. There are typically minor variations between each version
including the use of the term "webmail" or minor customization
targeted towards the specific institution ("CALVIN WEBMAIL TEAM"). In
doing some research on one that we received today I found that Purdue
put out on alert on it:
http://www.purdue.edu/securePurdue/news/detail.cfm?NewsID=189

Replies typically go to a hotmail, live.com, or yahoo address. All of
the emails we have received have come through .edu mail servers.

Here's the message:
