DomainKeys Identified Mail, or DKIM, is a system for validating the genuineness of an email by using a digital signature. When DKIM is activated for a given domain, a public key is published to the global Domain Name System and a private one is kept on the mail server. When a new email message is sent, a signature is issued using the private key and when the message is received, that signature is verified by the incoming email server using the public key. In this way, the receiver can easily discern if the message is authentic or if the sender’s address has been spoofed. A mismatch will appear if the content of the email has been changed in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered emails are identical and that nothing has been attached or deleted. This email authentication system will strengthen your email security, as you can validate the genuineness of the important emails that you receive and your partners can do the exact same thing with the emails that you send them. Based on the particular email provider’s policy, an email message that fails the test may be removed or may reach the receiver’s inbox with a warning notification.
DomainKeys Identified Mail in Cloud Hosting
If you purchase any of the cloud services that we offer, the DomainKeys Identified Mail option will be enabled by default for any domain name that you add to your web hosting account, so you won’t need to create any records or to activate anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our MX and NS records (so that the emails related to this domain will be handled by our cloud web hosting platform), a private cryptographic key will be created immediately on our email 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 will be protected by DomainKeys Identified Mail, so if you send out emails such as regular newsletters, they will reach their target destination and the receivers will be sure that they are genuine, because the DKIM option makes it impossible for unauthorized parties to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
All necessary DomainKeys Identified Mail records will be set up automatically by our cloud platform when you add a domain name as hosted in a semi-dedicated server account, so if you decide to use this type of hosting, you will not need to configure anything to be able to use the email authentication system. The domain must use our name servers in order for its DNS records to be managed on our end and in case this precondition is met, a private cryptographic key will be generated on our email servers and a public key will be published to the DNS system by a special TXT record. All email addresses that you set up using the domain will be protected by DomainKeys Identified Mail, which will make it impossible for 3rd parties to spoof any address. Both you and your partners or clients can benefit from this option, as it will ensure a much higher level of protection for your email correspondence.
