DomainKeys Identified Mail, or DKIM, is a system for confirming the genuineness of an email message using a digital signature. When DomainKeys Identified Mail is activated for a specific domain name, a public key is published to the global DNS system and a private one is stored on the mail server. If a new email is sent, a signature is issued using the private key and when the email is delivered, the signature is ‘scanned’ by the incoming mail server using the public key. Thus, the recipient can easily know if the message is legitimate or if the sender’s email address has been spoofed. A discrepancy will occur if the content of the email message has been modified in the meantime as well, so DKIM can also be used to make sure that the sent and the received email messages are identical and that nothing has been attached or deleted. This authentication system will strengthen your email security, as you can verify the genuineness of the important email messages that you get and your colleagues can do likewise with the messages that you send them. Depending on the given email provider’s adopted policy, a message that fails to pass the check may be erased or may emerge in the recipient’s mailbox with a warning notification.

DomainKeys Identified Mail in Cloud Hosting

In case you host a domain name in a cloud hosting account with our company, all the mandatory records for using the DomainKeys Identified Mail option will be added by default. This will happen as soon as you add the domain name in the Control Panel’s Hosted Domains section, provided that it also uses our NS records. A private cryptographic key will be generated on our mail servers, whereas a public key will be published to the DNS database automatically using the TXT record. In this way, you will not need to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your email messages will reach any target audience without being disallowed and nobody will be able to send emails faking your e-mail addresses. The latter is really important if the essence of your online presence suggests sending regular newsletters or offers via email to potential and existing clients.
