DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email message using an e-signature. When DKIM is enabled for a specific domain name, a public cryptographic key is published to the global DNS system and a private one is stored on the mail server. If a new message is sent, a signature is issued using the private key and when the email is received, the signature is authenticated by the incoming email server using the public key. Thus, the recipient can easily distinguish if the email is legitimate or if the sender’s email address has been forged. A mismatch will appear if the content of the email message has been edited on its way as well, so DKIM can also be used to ensure that the sent and the delivered emails are identical and that nothing has been attached or erased. This authentication system will increase your email safety, since you can validate the authenticity of the important emails that you get and your colleagues can do the same with the email messages that you send them. Based on the particular mail service provider’s adopted policies, an email that fails the examination may be erased or may reach the receiver’s mailbox with a warning alert.
DomainKeys Identified Mail in Semi-dedicated Hosting
When you opt for any of the Linux semi-dedicated hosting that we are offering, you’ll be able to use DKIM protection with any domain that you add to your brand new semi-dedicated server account without any manual setup, as our top-notch cloud hosting platform will create all the required records automatically, provided that the domain name uses our name servers. The latter is required for a TXT record to be set up for the domain, since this is how the public encryption key can become available in the global Domain Name System. The private key will also be added automatically to our mail servers, so every time you send out a new email message, it will have our platform’s electronic signature. The number of junk email messages keeps increasing each year and rather often fake addresses are used, but if you make use of our hosting services, you and your customers or associates will not need to worry about that.
