DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an email message has been sent by an authorized mail server or person. An electronic signature is attached to the email’s header using a private cryptographic key. When the email message is received, a public key that’s available in the global Domain Name System is used to validate who exactly sent it and whether the content has been modified in any way. The primary purpose of DomainKeys Identified Mail is to hamper the widespread scam and spam messages, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not receive the email at all, or you’ll get it with a warning that most probably it’s not a genuine one. It depends on mail service providers what exactly will happen with an email message which fails the signature check. DomainKeys Identified Mail will also give you an extra layer of security when you communicate with your business partners, for example, as they can see for themselves that all the emails that you exchange are legitimate and haven’t been meddled with on their way.

DomainKeys Identified Mail in Shared Hosting

In case you host a domain name in a shared hosting account with us, all the necessary records for using the DomainKeys Identified Mail feature will be set up by default. This will happen once you add the domain name in , as long as the domain also uses our NS resource records. A private cryptographic key will be created on our mail servers, whereas a public key will be sent to the DNS database automatically using the TXT record. In this way, you will not have to do anything manually and you’ll be able to take full advantage of all the benefits of this authentication system – your emails will be delivered to any destination without being disallowed and no one will be able to send out messages faking your e-mail addresses. The latter is quite important in case the nature of your worldwide web presence involves sending out regular offers or newsletters via email to potential and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

The DomainKeys Identified Mail option is offered by default with any domain that is added to a semi-dedicated server account with us. It must also use our name servers, so that its DNS resource records are managed by our system. The latter makes it possible for a special TXT resource record to be created, which is in fact the public key that verifies if a certain message is authentic or not. Such a record is created once a domain name is added to a semi-dedicated account through the Hepsia Control Panel and at the same time, a private key is created on our email servers. If you make use of our web and email hosting services, your emails will always reach their target viewers and you will not have to worry about unsolicited persons spoofing your addresses for spamming or scamming purposes, which is something very important if you use emails to reach your business collaborators.
