DomainKeys Identified Mail, or DKIM, is a method for checking the genuineness of an email message by using a digital signature. When DKIM is enabled for a particular domain name, a public encryption key is published to the global DNS system and a private one is stored on the email server. If a new message is sent, a signature is generated using the private key and when the message is received, the signature is ‘scanned’ by the incoming server using the public key. Thus, the receiver can easily know if the email message is genuine or if the sender’s email address has been forged. A mismatch will occur if the content of the email message has been edited on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered messages are identical and that nothing has been attached or erased. This email authentication system will boost your email security, as you can validate the legitimacy of the important email messages that you get and your partners can do the exact same thing with the email messages that you send them. Based on the given email provider’s policy, a message that fails to pass the check may be removed or may be delivered to the receiver’s mailbox with a warning notification.

DomainKeys Identified Mail in Shared Website Hosting

When you buy one of the Linux shared website hosting packages that we are offering, the DomainKeys Identified Mail functionality will be enabled by default for any domain that you add to your shard hosting account, so you will not have to create any records or to do anything manually. When a domain name is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our MX and NS records (so that the emails related to this domain will be handled by our cloud web hosting platform), a private encryption key will be generated instantaneously on our email servers and a TXT resource record with a public key will be sent to the global Domain Name System. All email addresses set up using this domain name will be protected by DomainKeys Identified Mail, so if you send emails such as periodic newsletters, they will reach their target audience and the receivers will know that they are legitimate, since the DKIM option makes it impossible for unsolicited people to forge your e-mail addresses.
