DomainKeys Identified Mail (DKIM) is an authentication system used to check that an email has been sent by an authorized individual or mail server. An e-signature is attached to the email’s header using a private cryptographic key. When the email is received, a public key that’s available in the global DNS database is used to check who exactly sent it and if its content has been altered in some way. The prime function of DKIM is to stop the widespread spam and scam messages, as it makes it impossible to forge an email address. If an email is sent from an address claiming to belong to your bank, for instance, but the signature doesn’t correspond, you will either not get the message at all, or you will get it with an alert that most probably it’s not genuine. It depends on email providers what exactly will happen with an email which fails to pass the signature test. DKIM will also offer you an additional safety layer when you communicate with your business partners, for example, as they can see that all the email messages that you send are legitimate and haven’t been modified in the meantime.

DomainKeys Identified Mail in Shared Hosting

In case you host a domain in a shared hosting account from us, all the compulsory records for using the DomainKeys Identified Mail option will be created by default. This will happen once you add the domain in the Control Panel’s Hosted Domains section, as long as the domain also uses our NS records. A private encryption key will be generated on our mail servers, whereas a public key will be added to the global Domain Name System automatically by using the TXT resource record. In this way, you will not need to do anything manually and you’ll be able to take advantage of all the benefits of this email validation system – your emails will be delivered to any target audience without being rejected and no one will be able to send email messages forging your addresses. The latter is really important in case the nature of your web presence involves sending out periodic offers or newsletters via email to prospective and current clients.

DomainKeys Identified Mail in Semi-dedicated Hosting

All required DKIM records will be set up automatically by our cloud hosting platform when you add a domain name as hosted in your semi-dedicated server account, so in case you choose to use this type of hosting, you won’t need to configure anything to be able to take advantage of the email validation system. The domain name must use our name servers in order for its DNS resource records to be managed on our end and provided that this prerequisite is satisfied, a private key will be generated on our email servers and a public key will be published to the Domain Name System by a special TXT 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 fake any email address. Both you and your partners or customers can benefit from this service, since it will ensure a higher level of security for your online communication.
