Does Something Smell Phishy?

Via Adam Gaffin, here is MailFrontier's phishing IQ quiz. Put yourself into the place of an end-user, with no particular knowledge of mail headers and HTML code, and see if you can tell the real messages from the frauds. I'm happy to report that I scored 100% -- but I have to admit that there were several that I really could have gone either way with, and probably would have resorted to checking the HTML had they appeared in my mailbox.
