DomainKeys Identified Mail (DKIM) is an email authentication system used to certify that an e-mail message has been sent by an authorized server or person. An electronic signature is added to the header of the email by using a private cryptographic key. When the email message is received, a public key that’s available in the global Domain Name System is used to check who exactly sent it and whether the content has been altered in some way. The essential function of DKIM is to prevent the widely spread scam and spam emails, as it makes it impossible to forge an email address. If an email is sent from an email address claiming to belong to your bank, for example, but the signature does not correspond, you will either not receive the email message at all, or you will get it with a warning notification that most probably it’s not genuine. It depends on email providers what exactly will happen with an email which fails the signature test. DomainKeys Identified Mail will also supply you with an additional safety layer when you communicate with your business partners, for example, since they can see for themselves that all the emails that you exchange are authentic and have not been modified in the meantime.

DomainKeys Identified Mail in Web Hosting

When you buy one of the web hosting packages that we offer, the DomainKeys Identified Mail functionality will be activated by default for any domain name that you add to your account, so you will not have to set up any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom Hepsia Control Panel using our NS and MX records (so that the email messages related to this domain name will be handled by our cloud hosting platform), a private cryptographic key will be issued instantly on our email servers and a TXT resource record with a public key will be sent to the DNS system. All email addresses set up with this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target audience and the recipients will know that the messages are legitimate, because the DomainKeys Identified Mail option makes it impossible for unauthorized parties to forge your e-mail addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

When you choose one of the Linux semi-dedicated hosting that we are offering, you will be able to use the DKIM option with any domain name that you register through your new semi-dedicated account without any manual setup, as our advanced cloud web hosting platform will create all the obligatory records automatically, as long as the domain name uses our name servers. The latter is required for a TXT record to be set up for the domain name, since this is how the public encryption key can become available in the global DNS system. The private key will also be added automatically to our mail servers, so every time you send a new email, it will carry our system’s electronic signature. The number of junk email messages keeps increasing each year and quite frequently forged email addresses are used, but if you make use of our hosting services, you and your customers or colleagues will not need to bother about that.
