DomainKeys Identified Mail, or DKIM, is a system for confirming the genuineness of an email message using an electronic signature. When DomainKeys Identified Mail is activated for a certain domain name, a public cryptographic key is published to the global DNS database and a private one is stored on the mail server. If a new email is sent, a signature is generated using the private key and when the email is delivered, that signature is ‘scanned’ by the incoming POP3/IMAP email server using the public key. In this way, the recipient can easily tell if the email is legitimate or if the sender’s email address has been forged. A discrepancy will appear if the content of the email message has been modified on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered messages are identical and that nothing has been attached or erased. This email authentication system will heighten your email security, as you can validate the legitimacy of the important emails that you receive and your associates can do likewise with the emails that you send them. Depending on the given email service provider’s policies, an email that fails to pass the test may be erased or may end up in the recipient’s inbox with a warning.

DomainKeys Identified Mail in Hosting

If you host a domain in a hosting account from us, all the obligatory records for using the DomainKeys Identified Mail feature will be created by default. This will happen once you add the domain name in the Control Panel’s Hosted Domains section, provided that it also uses our NS resource records. A private encryption key will be created on our mail servers, while a public key will be added to the global DNS system automatically by using the TXT record. In this way, you won’t need to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your messages will be delivered to any target audience without being disallowed and nobody will be able to send messages forging your email addresses. The latter is truly important if the essence of your web presence involves sending out regular newsletters or offers via email to prospective and current customers.

DomainKeys Identified Mail in Semi-dedicated Servers

All necessary DomainKeys Identified Mail records will be created automatically by our cloud hosting platform when you add a domain as hosted in a semi-dedicated server account, so if you decide to purchase a semi-dedicated server package, you won’t need to set up anything to be able to take advantage of the email validation system. The domain name must use our name servers so that its DNS resource records can be managed by our company and as long as this condition is met, a private cryptographic key will be generated on our mail servers and a public key will be added to the global Domain Name System by a special TXT record. All email addresses that you set up with the domain name will be protected by DKIM, which will make it impossible for 3rd parties to fake any email address. Both you and your associates or clients can take advantage of this feature, as it will guarantee a higher protection level for your e-correspondence.
