DomainKeys Identified Mail (DKIM) is an authentication system used to check that an e-mail message has been sent by an authenticated person or server. A digital signature is added to the header of the email message by using a private cryptographic key. When the message is received, a public key that is available in the global Domain Name System is used to check who exactly sent it and if its content has been altered in some way. The prime task of DKIM is to obstruct the widespread 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 instance, but the signature doesn’t correspond, you will either not receive the email at all, or you will receive it with an alert that most likely it is not a legitimate one. It depends on mail service providers what exactly will happen with an email which fails the signature examination. DomainKeys Identified Mail will also offer you an extra security layer when you communicate with your business partners, for example, as they can see that all the messages that you send are authentic and have not been manipulated on their way.

DomainKeys Identified Mail in Hosting

When you purchase one of the Linux hosting plans that we are offering, the DomainKeys Identified Mail option will be activated by default for any domain name that you register under your website hosting account, so you won’t have to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our NS and MX resource records (so that the email messages related to this domain will be handled by our cloud platform), a private key will be created momentarily on our mail servers and a TXT record with a public key will be sent to the Domain Name System. All email addresses created using this domain will be protected by DKIM, so if you send out emails such as regular newsletters, they will reach their target destination and the recipients will know that they are genuine, since the DKIM functionality makes it impossible for unsolicited people to spoof your e-mail addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

All mandatory DKIM records will be created automatically by our cloud hosting platform when you add a domain name as hosted in your semi-dedicated server account, so in case you decide to get a semi-dedicated server plan, you won’t have to configure anything to be able to use the email authentication system. The domain should use our name servers so that its DNS resource records can be managed on our end and as long as this precondition is matched, a private key will be generated on our email servers and a public key will be added to the DNS system by a special TXT resource record. All email addresses that you set up using the domain will be protected by DKIM, which will make it impossible for third parties to fake any address. Both you and your partners or clients can benefit from this feature, since it will guarantee a much higher security level for your online communication.
