DomainKeys Identified Mail (DKIM) is an email authentication system used to prove that an email has been sent by an authenticated email server or individual. An electronic signature is added to the header of the email message by using a private key. When the email 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 any way. The principal function of DKIM is to hinder the widely spread scam and spam messages, 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 does not correspond, you will either not get the email message at all, or you’ll receive it with a warning that most likely it is not genuine. It depends on mail service providers what exactly will happen with an email which fails to pass the signature examination. DomainKeys Identified Mail will also provide you with an additional protection layer when you communicate with your business allies, for instance, since they can see that all the email messages that you send are legitimate and have not been tampered with on their way.

DomainKeys Identified Mail in Cloud Hosting

When you buy one of the Linux cloud hosting services that we’re offering, the DomainKeys Identified Mail option will be enabled as standard for any domain that you register under your website hosting account, so you will not have to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS resource records (so that the emails related to this domain name will be handled by our cloud platform), a private cryptographic key will be generated immediately on our email servers and a TXT record with a public key will be sent to the DNS system. All addresses set up with this domain name will be protected by DomainKeys Identified Mail, so if you send out email messages such as regular newsletters, they will reach their target destination and the receivers will be sure that the messages are genuine, since the DKIM functionality makes it impossible for unauthorized persons to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

When you select any of the semi-dedicated hosting services offered by our company, you’ll be able to use the DKIM feature with any domain that you add to your new account without any manual intervention, as our high-tech cloud platform will create all the necessary records automatically, provided that the domain name uses our name servers. The latter is needed for a TXT record to be set up for the domain, as this is how the public cryptographic key can become available in the global DNS database. The private key will also be added automatically to our mail servers, so every time you send a new email message, it will include our system’s digital signature. The number of unsolicited bulk email messages keeps growing each year and very often counterfeit email addresses are used, but if you make use of our web hosting services, you and your customers or colleagues won’t have to bother about that.
