DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email using a digital signature. When DKIM is enabled for a certain domain, a public cryptographic key is published to the global DNS database and a private one is kept on the email server. When a new email message is sent, a signature is issued using the private key and when the email is delivered, the signature is authenticated by the incoming mail server using the public key. Thus, the recipient can easily discern if the email is legitimate or if the sender’s email address has been forged. 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 ensure that the sent and the delivered messages are identical and that nothing has been added or removed. This email authentication system will boost your email security, as you can verify the legitimacy of the important emails that you get and your partners can do the same with the emails that you send them. Depending on the particular mail service provider’s policy, an email that fails the test may be removed or may appear in the receiver’s inbox with a warning flag.
DomainKeys Identified Mail in Cloud Website Hosting
If you purchase one of the Linux cloud website hosting that we offer, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you add to your website hosting account, so you will not have to create any records or to activate anything manually. When a domain is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our NS and MX records (so that the emails associated with this domain will be handled by our cloud hosting platform), a private key will be created right away on our mail servers and a TXT resource record with a public key will be sent to the global DNS system. All email addresses created with this domain name will be protected by DomainKeys Identified Mail, so if you send emails such as regular newsletters, they will reach their target destination and the receivers will be sure that they are legitimate, since the DKIM feature makes it impossible for unsolicited persons to spoof your addresses.
