DomainKeys Identified Mail (DKIM) is a validation system used to certify that an e-mail message has been sent by an authenticated person or email server. An electronic signature is added to the email’s header by using a private encryption key. When the message is received, a public key that’s available in the global Domain Name System is used to confirm who actually sent it and if its content has been changed in any way. The primary job of DomainKeys Identified Mail is to stop the widely spread spam and scam emails, 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 does not match, you will either not receive the message at all, or you’ll get it with a warning that most likely it’s not an authentic one. It depends on mail service providers what exactly will happen with an email message that fails to pass the signature check. DomainKeys Identified Mail will also give you an extra security layer when you communicate with your business associates, for instance, as they can see that all the e-mails that you send are authentic and haven’t been manipulated on their way.

DomainKeys Identified Mail in Hosting

If you host a domain in a hosting account from our company, all the required records for using the DomainKeys Identified Mail feature will be created by default. This will happen the moment you add the domain in the Control Panel’s Hosted Domains section, as long as the domain also uses our NS resource records. A private cryptographic key will be generated on our email servers, whereas a public key will be added to the global Domain Name System automatically using the TXT record. In this way, you won’t have to do anything manually and you’ll be able to make use of all the benefits of this email authentication system – your email messages will be delivered to any target audience without being discarded and no one will be able to send out emails faking your addresses. The latter is pretty important in case the type of your web presence suggests sending out periodic newsletters or offers via email to potential and current clients.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so if you pick a semi-dedicated server plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the validation system will be set up automatically – a private key on our mail servers for the e-signature and a TXT resource record carrying the public key for the DNS system. As the protection is set up for a particular domain name, all e-mail addresses created with it will carry a signature, so you will not need to worry that the email messages that you send may not reach their destination email address or that somebody may forge any of your email addresses and try to spam/scam people. This may be really important if you use electronic communication in your business, as your associates and/or customers will be able to distinguish genuine messages from false ones.
