DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email by using an electronic signature. When DKIM is activated for a specific domain, a public cryptographic key is published to the global Domain Name System and a private one is kept on the email server. When a new message is sent, a signature is generated using the private key and when the email is received, that signature is authenticated by the incoming mail server using the public key. Thus, the recipient can easily recognize if the email message is legitimate or if the sender’s address has been spoofed. A mismatch will appear if the content of the email message has been changed in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received messages are identical and that nothing has been added or removed. This email validation system will heighten your email safety, since you can verify the legitimacy of the important email messages that you get and your partners can do the same with the emails that you send them. Depending on the given email provider’s adopted policies, a message that fails the test may be erased or may emerge in the recipient’s inbox with a warning sign.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail functionality is pre-enabled for all domains that are hosted in a cloud hosting account on our cloud platform, so you will not have to do anything on your end to enable it. The sole requirement is that the particular domain name should be hosted in a website hosting account on our platform using our NS and MX resource records, so that the e-mails will go through our email servers. The private key will be generated on the server and the TXT resource record, which includes the public key, will be published to the DNS system automatically, so you will not have to do anything manually on your end in order to enable this option. The DKIM validation system will permit you to send out trustable emails, so if you are sending offers or a newsletter to clients, for example, your emails will always reach their target viewers, whereas unauthorized third parties will not be able to spoof your email addresses.
