DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email message by using an e-signature. When DKIM is activated for a particular domain name, a public key is published to the global DNS system and a private one is stored on the mail server. When a new message is sent, a signature is generated using the private key and when the email message is received, the signature is authenticated by the incoming POP3/IMAP server using the public key. In this way, the receiver can easily recognize if the email message is authentic or if the sender’s email address has been spoofed. A discrepancy will appear if the content of the email message has been modified on its way 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 erased. This validation system will increase your email safety, since you can confirm the legitimacy of the important email messages that you get and your partners can do the same with the messages that you send them. Depending on the particular mail service provider’s adopted policies, an email that fails the examination may be erased or may enter the recipient’s mailbox with a warning alert.

DomainKeys Identified Mail in Shared Hosting

When you obtain one of the shared plans that we offer, the DomainKeys Identified Mail option will be enabled by default for any domain that you add to your hosting account, so you will not need to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our NS and MX resource records (so that the emails associated with this domain name will be handled by our cloud web hosting platform), a private cryptographic key will be created instantaneously 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 will be protected by DomainKeys Identified Mail, so if you send out emails such as periodic newsletters, they will reach their target audience and the recipients will be sure that they are authentic, since the DomainKeys Identified Mail option makes it impossible for unauthorized parties to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

The DomainKeys Identified Mail feature is offered by default with any domain name that’s registered through a semi-dedicated server account with us. It should also use our name servers, so that its DNS resource records are handled by our system. The latter makes it possible for a special TXT resource record to be created, which is actually the public cryptographic key that confirms if a certain email is genuine or not. This record is set up the moment a domain is added to a semi-dedicated server account via the Hepsia Control Panel and in the meantime, a private key is generated on our email servers. If you make use of our web and email hosting services, your email messages will always reach their target destination and you will not have to worry about unsolicited parties forging your email addresses for scamming or spamming purposes, which is something really important in case you use emails to reach your business partners.
