Doppler allows you to implement DomainKeys ((personal authentication) in your deliveries. This technology developed jointly by Yahoo!, Cisco, Sendmail and PGP Corporation, improves the security of email against fraudulent messages and phishing by means of a new standard of secure email called DomainKeys Identified Mail (DKIM) which has already been approved by the Internet Engineering Task Force (IETF), the group with responsibility for technical standards on the Internet. DKIM uses signature encryption technology through a public key and a private key to verify the authenticity of the domain of the senders of the email. With this verification, email authentication occurs and is delivered to the recipient´s mailbox.
In order for you to apply DomainKeys to Doppler you must enter the Control Panel of your account, click on the DomainKeys link and complete the registration form. After a brief approval process, Doppler will generate some TXT logs that you will have to add in the Domain Name Servers of your Domain. Once the logs are added, you can activate DomainKeys from your Control Panel. The activation of DomainKeys for your domain is free and you can see a tutorial on how to do it here.
