DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an e-mail has been sent by an authorized email server or individual. A digital signature is attached to the header of the message 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 verify who exactly sent it and if its content has been changed in any way. The chief purpose of DKIM is to hamper the widespread spam and scam email messages, as it makes it impossible to forge an email address. If a message is sent from an email address claiming to belong to your bank, for example, but the signature doesn’t correspond, you will either not receive the email message at all, or you’ll get it with a warning alert that most likely it’s not authentic. It depends on email service providers what exactly will happen with an email message which fails to pass the signature test. DKIM will also offer you an extra security layer when you communicate with your business associates, for instance, since they can see for themselves that all the messages that you exchange are legitimate and haven’t been tampered with on their way.

DomainKeys Identified Mail in Shared Hosting

If you obtain any of the Linux shared hosting packages that we are offering, the DomainKeys Identified Mail feature will be activated by default for any domain name that you add to your website hosting 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 in-house developed Hepsia Control Panel using our MX and NS resource records (so that the email messages associated with this domain name will be handled by our cloud platform), a private key will be created momentarily on our email servers and a TXT resource record with a public key will be sent to the global Domain Name System. All addresses created using this domain will be protected by DKIM, so if you send emails such as regular newsletters, they will reach their target audience and the recipients will be sure that they are authentic, as the DomainKeys Identified Mail functionality makes it impossible for unauthorized individuals to spoof your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

When you opt for one of the Linux semi-dedicated hosting packages that we offer, you will be able to use the DKIM feature with any domain name that you add to your brand-new semi-dedicated hosting account without any manual setup, as our outstanding cloud platform will set up all the required records automatically, on the condition that the domain uses our name servers. The aforementioned is required for a TXT resource record to be set up for the domain, since 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 email servers, so whenever you send a new message, it will have our platform’s e-signature. The number of spam messages keeps growing every year and rather frequently bogus email addresses are used, but if you make use of our hosting services, you and your clients or colleagues will not have to bother about that.
