DomainKeys Identified Mail, or DKIM, is a method for validating the genuineness of an email message using an electronic signature. When DKIM is enabled for a certain 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 message is delivered, the signature is authenticated by the POP3/IMAP mail server using the public key. Thus, the receiver can easily recognize if the email is authentic or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email message has been altered in the meantime as well, so DKIM can also be used to make sure that the sent and the delivered emails are identical and that nothing has been attached or removed. This validation system will increase your email safety, since you can validate the legitimacy of the important emails that you get and your associates can do the same with the email messages that you send them. Depending on the particular mail service provider’s policy, an email message that fails the check may be removed or may enter the recipient’s inbox with a warning sign.
DomainKeys Identified Mail in Cloud Hosting
When you obtain any of the Linux cloud hosting that we offer, the DomainKeys Identified Mail option will be activated as standard for any domain name that you add to your shared website hosting account, so you will not have to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our MX and NS records (so that the email messages related to this domain will be handled by our cloud web hosting platform), a private key will be created instantly on our email servers and a TXT resource record with a public key will be sent to the global DNS database. All addresses created with this domain will be protected by DKIM, so if you send emails such as regular newsletters, they will reach their target audience and the recipients will be sure that they are legitimate, as the DKIM feature makes it impossible for unsolicited parties to spoof your addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
All obligatory DKIM records will be set up automatically by our cloud web hosting platform when you add a domain as hosted in a semi-dedicated server account, so if you decide to order a semi-dedicated server plan, you will not need to set up anything to be able to use the email authentication system. The domain should use our name servers in order for its DNS resource records to be managed by us and provided that this requirement is satisfied, a private key will be created on our mail servers and a public key will be published to the global DNS database by a special TXT resource record. All addresses that you set up using the domain will be protected by DomainKeys Identified Mail, which will make it impossible for 3rd parties to forge any email address. Both you and your partners or clients can benefit from this option, as it will ensure a much higher level of safety for your email communication.
