Iconix eMail ID is a client application that verifies the sender of an incoming email, and guarantees that the mail is actually coming from the company that it claims.
The service only works with companies that have registered with Iconix, which currently includes more than 300 companies such as eBay, PayPal, Citibank, Amazon.com, Expedia, and many others. Whenever an email arrives from one of the known senders, it is authenticated, and an icon displayed next to the message that indicates the validity of the mail.
Once Iconix is installed on your computer, it will automatically verify email messages whenever you use any of the supported services, there is no interface or additional configuration required. If are concerned about phishing scams involving major companies, give this software a try.
Iconix eMail ID supports IE and Firefox and works with Gmail, Yahoo, MSN and Hotmail accounts as well as Outlook Express.
