In joint effort, these companies have created a new safety standard in order to protect users from fraudulent activities. The DomainKeys Identified Mail - DKIM - standard embeds signature authentication into senders' domains and has already been approved by the Internet Engineering Task Force - IETF -, the international community concerned with Internet related standards, education and policy.

How does it work?

It's simple. For example, when PayPal sends an email to a user, the company's server will automatically embed a digital signature into the original message. Now, let's suppose that the recipient owns a Yahoo Mail address: Yahoo Email Servers will be able to instantly verify that the message has been sent by PayPal by inspecting the digital signature embedded in the email. If the digital signature cannot be verified, then the email is probably spam or phishing.
The DomainKeys Identified Mail - DKIM - system has both a public and a private key. The public key consists in the domain's DNS, and the private one is used to digitally sign the emails. Once the public and the private keys are verified, the email authentication is issued and, the email is then delivered to the recipient's inbox.
As a result of our constant evolution, Doppler allows you to apply DKIM to your email.
