PayPal and its owner eBay have announced a link-up with Google's Gmail webmail service to protect consumers against fraudulent e-mails and phishing attacks.
Gmail account holders will receive fewer fake e-mails claiming to be sent by eBay and PayPal.
DomainKeys and DomainKeys Identified Mail e-mail authentication technology allows Google to prevent the delivery to Gmail inboxes of messages fraudulently claiming to be from eBay and PayPal.
Garreth Griffith, head of risk management at PayPal UK, said, "The Gmail team's decision to work with eBay and PayPal on this issue is a significant step forward in our fight to keep consumers safe from phishing and cybercrime.
"Today's announcement will enhance online safety for millions of eBay and PayPal customers who use Gmail."
DomainKeys technology adds another layer to spam and phishing protection by allowing internet service providers to determine if messages are real and whether they should be delivered to a customer's inbox.
