There are several services (some of them are mentioned in my previous posts) to recognize a legitimate email, Google introduced a new anti-fishing feature to their free Gmail service. It displays a key icon (see screen shot below) next to authenticated messages from certain senders that spammers attempt to fake.
Even though currently it works only for mail from PayPal and eBay, it is more fast and reliable than other such solutions. “Now any email that claims to come from “paypal.com” or “ebay.com” (and their international versions) are authenticated by Gmail and -- here comes the important part -- rejected if it fails to verify as actually coming from PayPal or eBay”.

Now you can see a key icon (see screen shot) next to your Paypal or ebay email, if it is legitimate.
If Gmail introduced this feature for more services, especially for banking services, phishing attacks can be reduced to a large extent.(via )
