DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email message by using an electronic signature. When DKIM is enabled for a certain domain name, a public key is published to the global Domain Name System and a private one is stored on the email server. If a new email is sent, a signature is issued using the private key and when the message is delivered, that signature is ‘scanned’ by the receiving server using the public key. Thus, the recipient can easily tell if the email is genuine or if the sender’s address has been forged. A mismatch will appear if the content of the email message has been altered in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered messages are identical and that nothing has been added or erased. This email validation system will increase your email safety, since you can verify the legitimacy of the important emails that you receive and your associates can do likewise with the emails that you send them. Based on the given email provider’s adopted policies, an email that fails the test may be removed or may enter the recipient’s mailbox with a warning symbol.

DomainKeys Identified Mail in Shared Hosting

If you purchase one of the shared plans that we’re offering, the DomainKeys Identified Mail functionality will be enabled by default for any domain that you register under your website hosting account, so you won’t need to set up any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our NS and MX records (so that the emails related to this domain will be handled by our cloud hosting platform), a private cryptographic key will be created instantly on our email servers and a TXT resource record with a public key will be sent to the global DNS database. All email addresses created with this domain will be protected by DomainKeys Identified Mail, so if you send emails such as regular newsletters, they will reach their target audience and the recipients will be sure that the messages are authentic, as the DKIM feature makes it impossible for unauthorized individuals to spoof your addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated plans come with DKIM activated by default, so if you choose a semi-dedicated hosting package and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the validation system will be created automatically – a private key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the DNS database. As the protection is set up for a certain domain, all addresses created under it will have a signature, so you will not have to worry that the messages that you send may not be delivered to their destination address or that somebody may forge any of your addresses and try to scam/spam people. This may be very important in case you rely on email communication in your business, as your associates and/or clients will be able to distinguish authentic messages from counterfeit ones.
