DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an email message has been sent by an authenticated person or server. An e-signature is attached to the message’s header 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 confirm who exactly sent it and if the content has been changed in some way. The primary function of DKIM is to obstruct the widespread scam and spam messages, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank, for instance, but the signature doesn’t match, you will either not get the message at all, or you’ll get it with a warning note that most likely it is not legitimate. It depends on email providers what exactly will happen with an email that fails to pass the signature test. DKIM will also supply you with an extra security layer when you communicate with your business allies, for example, since they can see for themselves that all the messages that you exchange are legitimate and haven’t been modified on their way.

DomainKeys Identified Mail in Shared Web Hosting

If you purchase any of the shared web hosting that we’re offering, the DomainKeys Identified Mail option will be activated by default for any domain that you add to your website hosting account, so you won’t need to create any records or to activate anything manually. When a domain is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our NS and MX resource records (so that the email messages related to this domain name will be handled by our cloud platform), a private key will be generated right away on our email servers and a TXT record with a public key will be sent to the global DNS database. All email addresses created with this domain will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target destination and the receivers will know that they are authentic, since the DKIM option makes it impossible for unsolicited people to spoof your addresses.
