DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email using a digital signature. When DomainKeys Identified Mail is enabled for a given domain name, a public cryptographic key is published to the global Domain Name System and a private one is kept on the mail server. When a new message is sent, a signature is issued using the private key and when the message is delivered, the signature is authenticated by the incoming POP3/IMAP email server using the public key. In this way, the receiver can easily discern if the message is genuine or if the sender’s email address has been forged. A mismatch will appear if the content of the email message has been edited in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or deleted. This validation system will strengthen your email security, as you can verify the legitimacy of the important email messages that you get and your partners can do the exact same thing with the email messages that you send them. Based on the given email service provider’s adopted policies, an email message that fails to pass the test may be deleted or may show up in the receiver’s inbox with a warning notification.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail option is activated by default for all domains that are hosted in a web hosting account on our cloud servers, so you will not need to do anything yourself to enable it. The only requirement is that the given domain should be hosted in a website hosting account on our end using our NS and MX resource records, so that the emails will go through our mail servers. The private key will be created on the server and the TXT resource record, which contains the public key, will be published to the DNS database automatically, so you will not need to do anything manually on your end in order to enable this functionality. The DomainKeys Identified Mail email validation system will permit you to send out credible email messages, so if you are sending a newsletter or offers to customers, for example, your email messages will always reach their target viewers, whereas unsolicited 3rd parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

The DomainKeys Identified Mail option comes by default with any domain name that’s registered through a semi-dedicated server account with our company. The domain must also use our name servers, so that its DNS resource records are managed by our system. The latter makes it possible for a special TXT record to be created, which is in fact the public cryptographic key that confirms if a specific email is legitimate or not. Such a record is created as soon as a brand-new domain is added to a semi-dedicated account through the Hepsia Control Panel and in the meantime, a private key is created on our email servers. If you use our email and web hosting services, your messages will always reach their target readers and you won’t need to worry about unauthorized persons spoofing your email addresses for scamming or spamming purposes, which is essential if you use emails to get in touch with your business collaborators.
