DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email message using a digital signature. When DKIM is activated for a given domain name, a public encryption key is published to the global DNS database and a private one is kept on the email server. When a new email is sent, a signature is generated using the private key and when the email is delivered, that signature is verified by the incoming email server using the public key. In this way, the receiver can easily tell if the message is genuine or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email has been changed in the meantime as well, so DKIM can also be used to make sure that the sent and the delivered messages are identical and that nothing has been added or deleted. This authentication system will heighten your email safety, since you can validate the legitimacy of the important emails that you get and your partners can do the exact same thing with the messages that you send them. Based on the particular mail service provider’s policies, a message that fails to pass the examination may be removed or may emerge in the receiver’s mailbox with a warning alert.

DomainKeys Identified Mail in Cloud Hosting

If you purchase any of the Linux cloud hosting packages that we offer, the DomainKeys Identified Mail functionality will be enabled by default for any domain that you add to your shared 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 in-house developed Hepsia Control Panel using our MX and NS records (so that the emails associated with this domain will be handled by our cloud platform), a private encryption key will be created momentarily on our email servers and a TXT record with a public key will be sent to the DNS database. All email addresses set up using this domain name will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target audience and the recipients will know that they are authentic, since the DomainKeys Identified Mail option makes it impossible for unsolicited individuals to forge your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

All necessary DomainKeys Identified Mail records will be created automatically by our cloud web hosting platform when you add a domain name as hosted in a semi-dedicated server account, so in case you decide to purchase a semi-dedicated server package, you will not need to configure anything to be able to use the email authentication system. The domain should use our name servers so that its DNS records can be managed by us and if this condition is met, a private encryption key will be created on our mail servers and a public key will be sent to the global DNS system by a special TXT record. All addresses that you set up with the domain will be protected by DomainKeys Identified Mail, which will make it impossible for third parties to forge any email address. Both you and your partners or customers can benefit from this option, as it will ensure a higher protection level for your electronic correspondence.
