If your email account is with Google or Yahoo, your days of seeing phishing emails from fake eBay or PayPal addresses should be over. Google announced last week that it’s now using DomainKeys to verify messages really do come from paypal.com or ebay.com—if they don’t, they never even make it to your In Box. This is possible because eBay and PayPal are now making sure “that all their email is signed with DomainKeys and DKIM.” Since Yahoo! also uses DomainKeys and DKIM (they developed it, in fact), phishing attacks for Yahoo! Mail accounts should also disappear.
