DomainKeys Identified Mail, or DKIM, is a method for checking the authenticity of an email message by using a digital signature. When DomainKeys Identified Mail is activated for a certain domain name, a public encryption key is published to the global DNS database 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 message is delivered, that signature is ‘scanned’ by the receiving server using the public key. In this way, the receiver can easily distinguish if the message is legitimate or if the sender’s email address has been forged. A mismatch will occur if the content of the email message has been edited in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received messages are identical and that nothing has been attached or removed. This email authentication system will heighten your email safety, since you can validate the genuineness of the important emails that you receive and your colleagues can do likewise with the email messages that you send them. Based on the given email provider’s policy, a message that fails the examination may be erased or may be delivered to the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail option is pre-enabled for all domain names that are hosted in a cloud hosting account on our cloud platform, so you won’t need to do anything on your end to activate it. The sole requirement is that the given domain should be hosted in a website hosting account on our platform using our NS and MX records, so that the emails will go through our email servers. The private cryptographic key will be created on the server and the TXT resource record, which contains the public key, will be published to the Domain Name System automatically, so you won’t need to do anything manually on your end in order to activate this option. The DKIM email authentication system will allow you to send trustworthy emails, so if you’re sending a newsletter or offers to customers, for instance, your email messages will always reach their target viewers, while unsolicited 3rd parties will not be able to spoof your email addresses.
