DomainKeys Identified Mail (DKIM) is an authentication system used to prove that an e-mail message has been sent by an authenticated individual or server. An electronic signature is attached to the header of the email using a private encryption key. When the email message is received, a public key that’s available in the global Domain Name System is used to verify who exactly sent it and if its content has been modified in some way. The chief task of DKIM is to hinder 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 example, but the signature doesn’t match, you will either not get the email message at all, or you will receive it with a warning notice that most probably it is not a legitimate one. It depends on email service providers what exactly will happen with an email message that fails the signature check. DomainKeys Identified Mail will also give you an extra protection layer when you communicate with your business partners, for instance, as they can see that all the emails that you send are authentic and have not been modified on their way.

DomainKeys Identified Mail in Website Hosting

In case you host a domain name in a website hosting account with our company, all the required records for using the DomainKeys Identified Mail feature will be set up by default. This will happen once you add the domain name in the Control Panel’s Hosted Domains section, as long as it also uses our NS records. A private key will be generated on our email servers, while a public key will be published 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 full advantage of all the benefits of this authentication system – your messages will reach any target audience without being disallowed and nobody will be able to send emails forging your email addresses. The latter is quite important in case the nature of your web presence involves sending regular newsletters or offers via email to potential and existing customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail enabled by default, so in case you select a semi-dedicated server plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the email authentication system will be set up automatically – a private cryptographic key on our email servers for the e-signature and a TXT resource record carrying the public key for the global Domain Name System. Since the protection is set up for a certain domain name, all addresses created using it will carry a signature, so you will not need to worry that the email messages that you send out may not be delivered to their destination address or that someone may spoof any of your email addresses and attempt to spam/scam people. This may be very essential when you use electronic communication in your business, since your colleagues and/or customers will be able to distinguish genuine messages from forged ones.
