DomainKeys Identified Mail (DKIM) is an authentication system used to prove that an email message has been sent by an authorized server or individual. A digital signature is attached to the message’s header by using a private cryptographic key. When the email message is received, a public key that is available in the global DNS database is used to confirm who exactly sent it and if its content has been changed in some way. The principal function of DKIM is to avert the widespread spam and scam email messages, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature doesn’t match, you will either not receive the message at all, or you’ll receive it with a warning alert that most likely it is not legitimate. It depends on email providers what exactly will happen with an email message which fails to pass the signature test. DomainKeys Identified Mail will also provide you with an additional safety layer when you communicate with your business allies, for instance, since they can see for themselves that all the e-mail messages that you send are legitimate and have not been modified on their way.

DomainKeys Identified Mail in Shared Hosting

In case you host a domain in a shared hosting account with our company, all the obligatory records for using the DomainKeys Identified Mail functionality will be added by default. This will happen once you add the domain in the Control Panel’s Hosted Domains section, as long as it also uses our NS resource records. A private cryptographic key will be created on our email servers, while a public key will be published to the DNS database automatically using the TXT resource record. In this way, you will not need to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your messages will be sent to any target destination without being denied and nobody will be able to send out messages faking your e-mail addresses. The latter is quite important if the nature of your online presence involves sending regular offers or newsletters via email to potential and current clients.

DomainKeys Identified Mail in Semi-dedicated Hosting

All obligatory DKIM records will be created automatically by our cloud platform when you add a domain as hosted in your semi-dedicated server account, so if you choose to buy a semi-dedicated hosting package, you won’t need to configure anything to be able to use the email authentication system. The domain name should use our name servers in order for its DNS records to be managed on our end and in case this requirement is satisfied, a private encryption key will be generated on our mail servers and a public key will be sent to the DNS system by a special TXT record. All addresses that you create 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 colleagues or clients can take advantage of this functionality, since it will ensure a higher level of protection for your e-correspondence.
