DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email message using an electronic signature. When DKIM is activated for a certain domain name, a public cryptographic key is published to the global DNS database and a private one is kept on the email server. If a new email is sent, a signature is generated using the private key and when the email message is delivered, that signature is authenticated by the incoming server using the public key. In this way, the recipient can easily discern if the email is authentic or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email has been altered in the meantime as well, so DKIM can also be used to make sure that the sent and the delivered email messages are identical and that nothing has been attached or erased. This email validation system will boost your email security, since you can verify the genuineness of the important emails that you receive and your partners can do the exact same thing with the email messages that you send them. Based on the particular email provider’s policies, an email that fails the test may be removed or may enter the receiver’s inbox with a warning alert.

DomainKeys Identified Mail in Cloud Hosting

If you host a domain in a cloud hosting account with our company, all the required 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, as long as your domain also uses our NS records. A private encryption key will be generated on our mail servers, whereas a public key will be published to the Domain Name System automatically by using the TXT record. In this way, you will not have to do anything manually and you will be able to enjoy all the benefits of this email authentication system – your email messages will be sent to any destination without being denied and no one will be able to send messages faking your addresses. The latter is truly important in case the nature of your online presence suggests sending out periodic newsletters or offers via email to potential and existing clients.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated packages come with DomainKeys Identified Mail enabled by default, so if you select a semi-dedicated server package and you add a domain using our name servers via your Hepsia Control Panel, the records required for the validation system will be set up automatically – a private key on our email servers for the e-signature and a TXT resource record carrying the public key for the DNS system. As the protection is set up for a specific domain name, all addresses created under it will carry a signature, so you will not need to worry that the email messages that you send out may not be delivered to their target email address or that someone may forge any of your email addresses and try to scam/spam people. This may be quite important if you rely on email communication in your business, as your colleagues and/or clients will be able to distinguish authentic email messages from phony ones.
