Lifehacker.com posted a quiz created by MailFrontier designed to challenge your ability to pick out phisher e-mails from legitimate ones.
They must be getting a boatload of traffic from the link. The direct link to the quiz is currently not working (as of Thursday morning, around 11 am est).
But the comment thread on Lifehacker is interesting in and of itself. Several commenters raise the great point that two of the best ways to spot a phisher are not possible in the quiz:
Look at the raw source of the message to see if the code behind the links are really pointing to the server they claim to in the text of the message.
Look at the full mail header to see where the message was sent from.
