Just came across quite a useful tool...
ICONIX: Tired of trying to figure out which email messages might be phishing or fraudulent spam? Iconix eMail ID lets you see what's real before you even open the message. Iconix eMail ID works with your email program and double checks the source of a message to make sure it's not a spoof. It then uses a simple visual indicator in your inbox - a gold lock with a checkmark to show that a message is real. E-mail from over 300 major senders is currently identified--companies such as eBay, PayPal, Citibank, Amazon.com, Expedia, MySpace, and the New York Times represent the top online sites for retail, travel, auctions, banking, e-cards, news/entertainment, and dating. Version 3.15.16 added support for Mozilla Firefox and Internet Explorer 7.0 beta 2.
