DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email using an e-signature. When DKIM is activated for a specific domain, a public key is published to the global DNS database and a private one is stored on the mail server. If a new email message is sent, a signature is issued using the private key and when the email message is delivered, the signature is authenticated by the POP3/IMAP server using the public key. In this way, the recipient can easily know if the email message is legitimate or if the sender’s address has been forged. A mismatch will occur if the content of the email has been modified on its way 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 deleted. This authentication system will strengthen your email security, as you can verify the genuineness of the important email messages that you get and your colleagues can do the exact same thing with the emails that you send them. Depending on the particular email provider’s adopted policy, an email message that fails the test may be removed or may emerge in the receiver’s inbox with a warning sign.

DomainKeys Identified Mail in Cloud Web Hosting

When you purchase one of the cloud web hosting that we offer, the DomainKeys Identified Mail functionality will be enabled as standard for any domain name that you register under your website hosting account, so you will not have to set up any records or to do anything manually. When a domain name is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our NS and MX records (so that the email messages related to this domain will be handled by our cloud web hosting platform), a private encryption key will be created straight away on our email servers and a TXT record with a public key will be sent to the global Domain Name System. All email addresses set up using this domain will be protected by DomainKeys Identified Mail, so if you send out emails such as periodic newsletters, they will reach their target destination and the receivers will be sure that the messages are authentic, because the DomainKeys Identified Mail functionality makes it impossible for unsolicited persons to forge your e-mail addresses.
