DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email message using an electronic signature. When DKIM is activated for a particular domain name, a public encryption key is published to the global DNS database and a private one is stored on the email server. When a new message is sent, a signature is issued using the private key and when the email is delivered, that signature is authenticated by the incoming email server using the public key. Thus, the recipient can easily know if the email message is authentic or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email has been changed in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received email messages are identical and that nothing has been added or erased. This email authentication system will heighten your email security, as you can validate the legitimacy of the important emails that you get and your associates can do the same with the emails that you send them. Based on the particular mail service provider’s adopted policy, an email that fails to pass the examination may be deleted or may be delivered to the receiver’s mailbox with a warning alert.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail option is enabled by default for all domains that are hosted in a shared hosting account on our cloud servers, so you will not need to do anything yourself to activate it. The sole requirement is that the particular domain name should be hosted in a web hosting account on our platform using our MX and NS records, so that the e-mails will go through our mail servers. The private cryptographic key will be generated on the server and the TXT resource record, which includes the public key, will be published to the DNS system automatically, so you will not have to do anything manually on your end in order to activate this feature. The DKIM email authentication system will permit you to send credible emails, so if you are sending a newsletter or offers to clients, for example, your email messages will always reach their target audience, whereas unsolicited third parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our semi-dedicated packages come with DKIM activated by default, so in case you pick a semi-dedicated hosting plan and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the authentication system will be set up automatically – a private cryptographic key on our mail servers for the e-signature and a TXT record carrying the public key for the DNS system. As the DKIM protection is set up for a given domain, all addresses created under it will carry a signature, so you won’t need to worry that the emails that you send out may not be delivered to their destination address or that someone may spoof any of your addresses and try to scam/spam people. This may be rather important in case you use e-communication in your business, as your associates and/or clients will be able to distinguish genuine email messages from false ones.
