DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an e-mail message has been sent by an authorized individual or email server. A digital signature is added to the header of the email message by using a private key. When the message is received, a public key that is available in the global Domain Name System is used to verify who actually sent it and if the content has been altered in any way. The principal function of DKIM is to stop the widely spread spam and scam messages, as it makes it impossible to forge an email address. If an email message is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature doesn’t match, you will either not receive the message at all, or you will receive it with a warning that most probably it is not authentic. It depends on mail service providers what exactly will happen with an email message which fails to pass the signature check. DKIM will also supply you with an added layer of security when you communicate with your business associates, for example, as they can see for themselves that all the messages that you send are authentic and haven’t been modified in the meantime.

DomainKeys Identified Mail in Cloud Web Hosting

In case you host a domain name in a cloud web hosting account with our company, all the needed records for using the DomainKeys Identified Mail feature will be set up by default. This will happen the moment you add the domain name in the Hosted Domains section of the Hepsia Control Panel, as long as the domain also uses our NS records. A private encryption key will be generated on our email servers, whereas a public key will be added to the DNS system automatically by using the TXT resource record. Thus, you won’t have to do anything manually and you’ll be able to enjoy all the benefits of this email authentication system – your email messages will be sent to any audience without being denied and no one will be able to send email messages faking your addresses. The latter is very important in case the type of your Internet presence suggests sending out periodic newsletters or offers via email to potential and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

If you select one of the Linux semi-dedicated hosting offered by us, you will be able to use the DKIM feature with any domain name that you add to your brand new semi-dedicated account without any manual setup, as our top-notch cloud hosting platform will create all the needed records automatically, as long as the domain name uses our name servers. The latter is needed for a TXT resource record to be set up for the domain name, as this is how the public key can become available in the global Domain Name System. The private key will also be added automatically to our email servers, so anytime you send out a new email message, it will carry our system’s electronic signature. The number of spam email messages continues to grow every year and quite often forged email addresses are used, but if you use our hosting services, you and your customers or colleagues will not need to worry about that.
