DomainKeys Identified Mail, or DKIM, is a method for verifying the authenticity of an email message by using an e-signature. When DKIM is activated for a particular domain, a public key is published to the global Domain Name System and a private one is stored on the email server. If a new email is sent, a signature is generated using the private key and when the email is received, that signature is checked by the incoming server using the public key. Thus, the recipient can easily tell if the email message is legitimate or if the sender’s email address has been forged. A mismatch will occur if the content of the email has been edited on its way as well, so DKIM can also be used to make sure that the sent and the received messages are identical and that nothing has been attached or erased. This authentication system will increase your email safety, as you can verify the legitimacy of the important emails that you get and your colleagues can do likewise with the email messages that you send them. Based on the given mail service provider’s policy, a message that fails to pass the check may be deleted or may appear in the receiver’s mailbox with a warning notification.
DomainKeys Identified Mail in Semi-dedicated Hosting
All compulsory DomainKeys Identified Mail records will be set up automatically by our cloud hosting platform when you add a domain name as hosted in a semi-dedicated server account, so if you choose to buy a semi-dedicated hosting plan, you will not have to configure anything to be able to use the email authentication system. The domain should use our name servers in order for its DNS records to be managed on our end and if this prerequisite is matched, a private key will be created on our email servers and a public key will be added to the DNS system by a special TXT resource record. All addresses that you set up with the domain will be protected by DKIM, which will make it impossible for 3rd parties to fake any address. Both you and your partners or customers can take advantage of this functionality, as it will guarantee a higher level of safety for your email correspondence.
