DomainKeys Identified Mail, or DKIM, is a system for validating the legitimacy of an email message using an e-signature. When DKIM is enabled for a particular domain name, a public key is published to the global DNS database and a private one is kept on the mail server. If a new email is sent, a signature is generated using the private key and when the message is delivered, that signature is validated by the receiving server using the public key. Thus, the receiver can easily tell if the message is authentic or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email message has been modified in the meantime 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 removed. This email authentication system will increase your email safety, since you can confirm the authenticity of the important emails that you receive and your associates can do the same with the email messages that you send them. Depending on the given mail service provider’s policies, an email message that fails to pass the test may be removed or may be delivered to the recipient’s inbox with a warning sign.

DomainKeys Identified Mail in Cloud Website Hosting

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

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated plans come with DomainKeys Identified Mail activated by default, so if you pick a semi-dedicated server plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the validation system will be created automatically – a private encryption key on our mail servers for the digital signature and a TXT record carrying the public key for the DNS system. As the DKIM protection is set up for a specific domain, all addresses created under it will have a signature, so you won’t have to worry that the messages that you send may not be delivered to their destination email address or that someone may spoof any of your email addresses and try to scam/spam people. This may be extremely important in case you use email communication in your business, since your colleagues and/or customers will be able to distinguish authentic messages from spoofed ones.
