DomainKeys Identified Mail, or DKIM, is a method for confirming the legitimacy of an email message using a digital signature. When DomainKeys Identified Mail is enabled 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 issued using the private key and when the email message is received, that signature is checked by the incoming mail server using the public key. In this way, the receiver can easily know if the email is genuine or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email has been modified on its way as well, so DKIM can also be used to ensure that the sent and the delivered emails are identical and that nothing has been added or deleted. This email validation system will boost your email safety, since you can confirm the authenticity of the important email messages that you get and your partners can do the same with the messages that you send them. Based on the given email provider’s policy, an email that fails to pass the check may be removed or may be delivered to the recipient’s mailbox with a warning notification.

DomainKeys Identified Mail in Cloud Hosting

In case you host a domain in a cloud hosting account from us, all the necessary records for using the DomainKeys Identified Mail feature will be set up by default. This will happen the moment you add the domain name in the Control Panel’s Hosted Domains section, provided that it also uses our NS records. A private key will be created on our email servers, whereas a public key will be sent to the global DNS database automatically using the TXT resource record. In this way, you won’t have to do anything manually and you will be able to take full advantage of all the benefits of this validation system – your emails will be sent to any target audience without being rejected and nobody will be able to send out emails faking your e-mail addresses. The latter is quite important if the type of your online presence suggests sending regular offers or newsletters via email to prospective and existing customers.

DomainKeys Identified Mail in Semi-dedicated Servers

All obligatory DomainKeys Identified Mail records will be set up automatically by our cloud hosting platform when you add a domain as hosted in a semi-dedicated server account, so in case you choose to get a semi-dedicated hosting plan, you won’t have to set up anything to be able to take advantage of the email authentication system. The domain name should use our name servers so that its DNS resource records can be managed by our company and as long as this condition is fulfilled, a private encryption key will be generated on our email servers and a public key will be published to the DNS database by a special TXT record. All addresses that you create with the domain name will be protected by DomainKeys Identified Mail, which will make it impossible for 3rd parties to forge any address. Both you and your partners or clients can benefit from this functionality, since it will ensure a higher protection level for your electronic correspondence.
