DomainKeys Identified Mail, or DKIM, is a system for verifying the genuineness of an email message by using an electronic signature. When DomainKeys Identified Mail is enabled for a given domain, a public encryption key is published to the global DNS system and a private one is kept on the mail server. When a new email is sent, a signature is generated using the private key and when the email is delivered, that signature is authenticated by the incoming POP3/IMAP server using the public key. Thus, the recipient can easily recognize if the message is legitimate or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email has been modified in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been added or removed. This email authentication system will increase your email safety, as you can validate 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 mail service provider’s adopted policies, a message that fails the examination may be removed or may appear in the recipient’s inbox with a warning notification.

DomainKeys Identified Mail in Web Hosting

When you purchase one of the Linux web hosting that we are offering, the DomainKeys Identified Mail feature will be enabled as standard for any domain name that you register under your account, so you won’t need to create any records or to enable anything manually. When a domain is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain will be handled by our cloud web hosting platform), a private key will be generated momentarily on our mail servers and a TXT resource record with a public key will be sent to the Domain Name System. All addresses set up with this domain name will be protected by DomainKeys Identified Mail, so if you send out emails such as regular newsletters, they will reach their target destination and the receivers will know that they are authentic, as the DKIM functionality makes it impossible for unauthorized persons to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

All obligatory DomainKeys Identified Mail records will be created automatically by our cloud platform when you add a domain name as hosted in a semi-dedicated server account, so if you choose to purchase a semi-dedicated server package, you won’t have to set up anything to be able to take advantage of the email authentication system. The domain must use our name servers so that its DNS resource records can be managed by us and if this requirement is answered, a private cryptographic key will be generated on our mail servers and a public key will be sent to the Domain Name System by a special TXT resource record. All addresses that you create using the domain name will be protected by DKIM, which will make it impossible for third parties to fake any email address. Both you and your colleagues or clients can take advantage of this option, since it will ensure a much higher protection level for your e-correspondence.
