DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email using an e-signature. When DKIM is enabled for a given domain name, a public cryptographic key is published to the global DNS database and a private one is kept on the mail server. If a new email message is sent, a signature is issued using the private key and when the email is delivered, that signature is validated by the receiving server using the public key. Thus, the recipient can easily recognize if the email message is legitimate or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email message has been modified on its way as well, so DomainKeys Identified Mail 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 email authentication system will increase your email safety, as you can verify the legitimacy of the important email messages that you receive and your associates can do likewise with the messages that you send them. Based on the given email service provider’s adopted policies, an email message that fails the check may be deleted or may appear in the receiver’s inbox with a warning sign.
DomainKeys Identified Mail in Shared Hosting
The DomainKeys Identified Mail functionality is activated by default for all domains that are hosted in a shared hosting account on our cloud web hosting platform, so you won’t have to do anything yourself to enable it. The sole condition is that the given domain should be hosted in a website hosting account on our end using our MX and NS resource records, so that the email messages will go through our email servers. The private encryption key will be created on the server and the TXT record, which contains the public key, will be published to the global Domain Name System automatically, so you won’t have to do anything manually on your end in order to enable this option. The DomainKeys Identified Mail email authentication system will allow you to send out credible messages, so if you are sending a newsletter or offers to customers, for instance, your emails will always reach their target audience, whereas unsolicited 3rd parties won’t be able to forge your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated hosting packages come with DomainKeys Identified Mail enabled by default, so in case you pick a semi-dedicated hosting plan and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the validation system will be set up automatically – a private encryption key on our email servers for the e-signature and a TXT resource record carrying the public key for the global DNS system. Since the protection is set up for a certain domain name, all addresses created under it will carry a signature, so you won’t have to worry that the messages that you send out may not reach their destination address or that somebody may forge any of your addresses and try to scam/spam people. This may be quite important if you rely on e-communication in your business, as your colleagues and/or customers will be able to distinguish genuine email messages from forged ones.
