DomainKeys Identified Mail (DKIM) is an authentication system used to prove that an email message has been sent by an authorized person or email server. An electronic signature is attached to the message’s header using a private cryptographic key. When the message is received, a public key that’s available in the global DNS database is used to confirm who actually sent it and if its content has been modified in some way. The primary purpose of DKIM is to avert the widespread spam and scam messages, as it makes it impossible to fake an email address. If an email is sent from an address claiming to belong to your bank, for instance, but the signature doesn’t correspond, you will either not get the email message at all, or you will receive it with a warning note that most likely it’s not genuine. It depends on email providers what exactly will happen with an email message which fails to pass the signature check. DomainKeys Identified Mail will also provide you with an added protection layer when you communicate with your business partners, for example, since they can see for themselves that all the e-mail messages that you send are authentic and haven’t been manipulated on their way.

DomainKeys Identified Mail in Website Hosting

When you buy one of the Linux website hosting that we offer, the DomainKeys Identified Mail option will be activated as standard for any domain name that you register under your hosting account, so you won’t need to create any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our NS and MX resource records (so that the emails related to this domain will be handled by our cloud platform), a private cryptographic key will be created instantly on our mail servers and a TXT record with a public key will be sent to the global Domain Name System. All email addresses set up with this domain will be protected by DomainKeys Identified Mail, so if you send email messages such as periodic newsletters, they will reach their target audience and the receivers will know that the messages are genuine, because the DKIM feature makes it impossible for unauthorized individuals to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

All required DomainKeys Identified Mail records will be set up automatically by our cloud web hosting platform when you add a domain as hosted in a semi-dedicated server account, so in case you decide to get a semi-dedicated server package, you won’t need to configure anything to be able to use the email authentication system. The domain must use our name servers so that its DNS resource records can be managed on our end and as long as this condition is fulfilled, a private cryptographic key will be generated on our email servers and a public key will be added to the DNS system by a special TXT record. All email addresses that you set up using the domain will be protected by DKIM, which will make it impossible for 3rd parties to fake any email address. Both you and your colleagues or customers can take advantage of this functionality, since it will ensure a much higher security level for your online correspondence.
