DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an e-mail has been sent by an authorized individual or mail server. A digital signature is attached to the header of the email message using a private encryption key. When the message is received, a public key that’s available in the global Domain Name System is used to check who actually sent it and if its content has been altered in some way. The main task of DKIM is to hamper the widespread scam and spam email messages, as it makes it impossible to forge an email address. If a message is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature doesn’t correspond, you will either not get the email message at all, or you will get it with an alert that most probably it’s not a legitimate one. It depends on email providers what exactly will happen with an email message which fails the signature check. DomainKeys Identified Mail will also offer you an extra security layer when you communicate with your business allies, for instance, since they can see that all the emails that you send are genuine and have not been modified in the meantime.
DomainKeys Identified Mail in Cloud Web Hosting
If you host a domain in a cloud web hosting
account with us, all the mandatory records for using the DomainKeys Identified Mail feature will be added by default. This will happen once you add the domain name in the Control Panel’s Hosted Domains section, provided that your domain also uses our NS records. A private cryptographic key will be created on our email servers, whereas a public key will be published to the DNS database automatically using the TXT record. In this way, you will not have to do anything manually and you will be able to take advantage of all the benefits of this validation system – your messages will be delivered to any target audience without being denied and nobody will be able to send email messages forging your e-mail addresses. The latter is really important in case the nature of your Internet presence involves sending regular offers or newsletters via email to prospective and current customers.
DomainKeys Identified Mail in Semi-dedicated Hosting
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 in case you decide to get a semi-dedicated package, you will not have to set up anything to be able to take advantage of the email authentication system. The domain name must use our name servers in order for its DNS resource records to be managed by us and as long as this condition is answered, a private cryptographic key will be created on our email servers and a public key will be published to the DNS database by a special TXT resource record. All email addresses that you set up using the domain will be protected by DKIM, which will make it impossible for third parties to spoof any email address. Both you and your associates or clients can benefit from this option, since it will guarantee a higher safety level for your online communication.
