DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email message by using a digital signature. When DomainKeys Identified Mail is activated for a certain domain, a public encryption key is published to the global DNS system and a private one is stored on the mail server. If a new email is sent, a signature is issued using the private key and when the email is received, the signature is checked by the incoming POP3/IMAP email server using the public key. Thus, the recipient can easily recognize if the message is authentic or if the sender’s email address has been spoofed. A discrepancy will occur if the content of the email has been altered in the meantime as well, so DKIM can also be used to ensure that the sent and the received email messages are identical and that nothing has been attached or deleted. This validation system will increase your email security, as you can validate the genuineness of the important emails that you receive and your colleagues can do the exact same thing with the email messages that you send them. Depending on the given email service provider’s adopted policies, an email that fails to pass the examination may be deleted or may appear in the receiver’s inbox with a warning alert.

DomainKeys Identified Mail in Cloud Hosting

When you purchase one of the Linux cloud hosting that we’re offering, the DomainKeys Identified Mail functionality will be activated by default for any domain that you register under your website hosting account, so you won’t have to create any records or to do anything manually. When a domain name is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX resource records (so that the email messages associated with this domain name will be handled by our cloud web hosting platform), a private key will be created instantly on our mail servers and a TXT record with a public key will be sent to the global DNS database. All email addresses set up with this domain name will be protected by DomainKeys Identified Mail, so if you send emails such as regular newsletters, they will reach their target audience and the receivers will know that they are genuine, since the DomainKeys Identified Mail option makes it impossible for unsolicited people to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

The DomainKeys Identified Mail functionality is offered by default with any domain name that is added to a semi-dedicated server account with us. It should also use our name servers, so that its DNS records are managed by our system. The latter makes it possible for a special TXT record to be set up, which is in fact the public encryption key that confirms if a particular email message is legitimate or not. Such a record is set up as soon as a brand-new domain is registered in a semi-dedicated hosting account via the Hepsia Control Panel and in the meantime, a private key is generated on our mail servers. If you make use of our web and email hosting services, your emails will always reach their target readers and you will not need to worry about unauthorized individuals forging your addresses for scamming or spamming purposes, which is something rather important when you use email messages to reach your business collaborators.
