DomainKeys Identified Mail (DKIM) is a validation system used to check that an email message has been sent by an authorized mail server or person. A digital signature is added to the email’s header by using a private cryptographic key. When the email message is received, a public key that is available in the global Domain Name System is used to validate who actually sent it and whether its content has been altered in some way. The fundamental task of DomainKeys Identified Mail is to obstruct the widespread scam and spam emails, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank, for instance, but the signature doesn’t correspond, you will either not receive the email message at all, or you will get it with an alert that most probably it is not legitimate. It depends on email providers what exactly will happen with an email message that fails to pass the signature test. DKIM will also supply you with an extra layer of protection when you communicate with your business allies, for instance, as they can see that all the e-mails that you send are legitimate and haven’t been modified in the meantime.

DomainKeys Identified Mail in Shared Hosting

If you order one of the shared hosting that we are offering, the DomainKeys Identified Mail feature will be enabled as standard for any domain name that you add to your website hosting account, so you will not need to set up any records or to do 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 will be handled by our cloud web hosting platform), a private cryptographic key will be issued straight away on our email servers and a TXT resource record with a public key will be sent to the Domain Name System. All email addresses created using this domain will be protected by DomainKeys Identified Mail, so if you send out email messages such as periodic newsletters, they will reach their target destination and the receivers will be sure that they are legitimate, because the DomainKeys Identified Mail option makes it impossible for unauthorized parties to spoof your e-mail addresses.
