DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email using an e-signature. When DKIM is enabled for a certain domain, 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 issued using the private key and when the message is received, the signature is authenticated by the incoming POP3/IMAP mail server using the public key. Thus, the receiver can easily recognize 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 changed in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered emails are identical and that nothing has been added or deleted. This email authentication system will strengthen your email security, as you can verify the legitimacy of the important emails that you get and your partners can do the same with the email messages that you send them. Depending on the particular email provider’s policies, a message that fails the test may be removed or may show up in the receiver’s inbox with a warning symbol.

DomainKeys Identified Mail in Cloud Hosting

When you get one of the Linux cloud hosting that we are offering, the DomainKeys Identified Mail functionality will be enabled by default for any domain that you add to your web hosting account, so you won’t need to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX records (so that the emails associated with this domain name will be handled by our cloud hosting platform), a private cryptographic key will be generated right away on our email servers and a TXT record with a public key will be sent to the DNS system. All addresses set up with this domain name will be protected by DomainKeys Identified Mail, so if you send email messages such as regular newsletters, they will reach their target destination and the receivers will know that they are authentic, as the DomainKeys Identified Mail option makes it impossible for unsolicited persons to spoof your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

The DomainKeys Identified Mail option comes by default with any domain that’s added to a semi-dedicated server account with us. It must also use our name servers, so that its DNS records are managed by our platform. The latter makes it possible for a special TXT record to be set up, which is actually the public encryption key that confirms if a certain email message is legitimate or not. This record is set up once a domain name is registered in a semi-dedicated hosting account via the Hepsia Control Panel and at the same time, a private key is generated on our mail servers. If you make use of our email and web hosting services, your emails will always reach their target viewers and you will not need to worry about unauthorized persons forging your addresses for scamming or spamming purposes, which is something really important if you use email messages to touch base with your business collaborators.
