DomainKeys Identified Mail, or DKIM, is a method for checking the genuineness of an email message using an e-signature. When DKIM is activated for a particular domain name, a public 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 delivered, the signature is verified by the POP3/IMAP mail server using the public key. In this way, the recipient can easily tell if the email is genuine or if the sender’s email address has been forged. A discrepancy will appear if the content of the email has been modified on its way 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 attached or erased. This validation system will increase your email safety, as you can validate the legitimacy of the important email messages that you get and your associates can do the exact same thing with the emails that you send them. Depending on the particular mail service provider’s policy, a message that fails to pass the examination may be removed or may show up in the receiver’s mailbox with a warning notification.
DomainKeys Identified Mail in Cloud Web Hosting
When you obtain any of the Linux cloud web hosting packages that we offer, the DomainKeys Identified Mail feature will be enabled by default for any domain that you register under your shared 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 custom-built Hepsia Control Panel using our MX and NS resource records (so that the email messages related to this domain name will be handled by our cloud platform), a private key will be generated straight away on our email servers and a TXT resource record with a public key will be sent to the global DNS system. All addresses set up using this domain name will be protected by DomainKeys Identified Mail, so if you send out emails such as periodic newsletters, they will reach their target audience and the recipients will be sure that they are genuine, because the DomainKeys Identified Mail option makes it impossible for unauthorized people to spoof your email addresses.
