DomainKeys Identified Mail (DKIM) is an email validation system used to certify that an email message has been sent by an authorized individual or email server. A digital signature is added to the header of the email 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 validate who exactly sent it and whether its content has been modified in some way. The fundamental job of DKIM is to impede the widespread scam and spam email messages, as it makes it impossible to fake an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for example, but the signature does not match, you will either not receive the message at all, or you will receive it with a notification that most probably it’s not legitimate. It depends on email service providers what exactly will happen with an email message that fails to pass the signature check. DomainKeys Identified Mail will also offer you an additional protection layer when you communicate with your business partners, for instance, as they can see for themselves that all the emails that you send are legitimate and haven’t been tampered with on their way.

DomainKeys Identified Mail in Shared Web Hosting

If you host a domain name in a shared web hosting account with us, all the mandatory records for using the DomainKeys Identified Mail feature will be set up by default. This will happen once you add the domain in , as long as it also uses our NS records. A private encryption key will be created on our mail servers, whereas a public key will be sent to the global DNS system automatically by using the TXT resource record. In this way, you won’t have to do anything manually and you’ll be able to take advantage of all the benefits of this email validation system – your email messages will reach any audience without being denied and no one will be able to send out emails faking your e-mail addresses. The latter is really important in case the essence of your worldwide web presence suggests sending out regular newsletters or offers via email to potential and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

The DomainKeys Identified Mail feature is offered by default with any domain name that’s added to a semi-dedicated server account with us. It must also use our name servers, so that its DNS records are handled by our system. The latter makes it possible for a special TXT resource record to be set up, which is actually the public key that confirms if a given message is legitimate or not. This record is set up the moment a brand new domain is added to an account via the Hepsia Control Panel and at the same time, a private key is generated on our email servers. If you use our email and web hosting services, your messages will always reach their target destination and you won’t have to worry about unsolicited people forging your addresses for scamming or spamming purposes, which is something really important in case you use email messages to get in touch with your business allies.
