DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an email has been sent by an authorized server or person. An e-signature is attached to the header of the email message using a private encryption key. When the email message is received, a public key that is available in the global Domain Name System is used to validate who exactly sent it and if the content has been modified in some way. The chief purpose of DomainKeys Identified Mail is to avert the widespread scam and spam email messages, as it makes it impossible to fake an email address. If a message is sent from an email address claiming to belong to your bank, for instance, but the signature does not correspond, you will either not receive the email at all, or you will get it with a warning notification that most likely it’s not authentic. It depends on email providers what exactly will happen with an email message which fails to pass the signature test. DomainKeys Identified Mail will also offer you an extra security layer when you communicate with your business partners, for instance, as they can see for themselves that all the messages that you exchange are authentic and have not been tampered with in the meantime.

DomainKeys Identified Mail in Shared Web Hosting

When you buy any of the Linux shared web hosting that we offer, the DomainKeys Identified Mail functionality will be enabled by default for any domain name that you add to your shared website hosting account, so you will not need to set up 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 records (so that the emails associated with this domain will be handled by our cloud hosting platform), a private encryption 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 email addresses created with this domain will be protected by DomainKeys Identified Mail, so if you send out email messages such as regular newsletters, they will reach their target audience and the recipients will know that the messages are genuine, because the DomainKeys Identified Mail functionality makes it impossible for unauthorized parties to forge your email addresses.
