DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an email has been sent by an authenticated server or individual. A digital signature is added to the header of the email message by using a private encryption key. When the email message is received, a public key that is available in the global Domain Name System is used to confirm who exactly sent it and whether the content has been changed in some way. The primary job of DomainKeys Identified Mail is to hinder the widespread scam and spam email messages, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t correspond, you will either not get the message at all, or you’ll get it with a warning notification that most probably it is not authentic. It depends on mail service providers what exactly will happen with an email which fails the signature test. DomainKeys Identified Mail will also give you an additional safety layer when you communicate with your business partners, for instance, since they can see that all the email messages that you exchange are legitimate and have not been modified on their way.

DomainKeys Identified Mail in Cloud Website Hosting

You will be able to take advantage of DomainKeys Identified Mail with each and every Linux cloud website hosting service that we offer without having to do anything in particular, as the mandatory records for using this email validation system are set up automatically by our web hosting platform when you add a domain name to an existing hosting account via the Hepsia Control Panel. If the specific domain name uses our name server records, a private cryptographic key will be created and stored on our email servers and a TXT record with a public key will be sent to the global Domain Name System. In case you send out regular messages to clients or business allies, they’ll always be delivered and no unauthorized party will be able to spoof your email address and make it seem like you’ve composed a particular email message.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so in case you select a semi-dedicated plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the email validation system will be set up automatically – a private cryptographic key on our mail servers for the digital signature and a TXT record carrying the public key for the global Domain Name System. As the DKIM protection is set up for a specific domain name, all e-mail addresses created using it will carry a signature, so you won’t need to worry that the emails that you send may not be delivered to their target address or that somebody may forge any of your addresses and attempt to spam/scam people. This may be extremely important in case you rely on email communication in your business, as your colleagues and/or clients will be able to distinguish real emails from counterfeit ones.
