DomainKeys Identified Mail (DKIM) is an email validation system used to check that an email message has been sent by an authenticated individual or email server. A digital signature is added to the email message’s header using a private key. When the email message is received, a public key that’s available in the global DNS database is used to verify who actually sent it and whether its content has been modified in any way. The chief job of DKIM is to obstruct the widely spread scam and spam messages, as it makes it impossible to fake an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not match, you will either not get the email at all, or you’ll get it with a warning that most likely it’s not an authentic one. It depends on email service providers what exactly will happen with an email that fails to pass the signature check. DomainKeys Identified Mail will also provide you with an added protection layer when you communicate with your business allies, for instance, as they can see that all the emails that you exchange are authentic and have not been meddled with on their way.

DomainKeys Identified Mail in Hosting

If you obtain any of the Linux hosting packages that we offer, the DomainKeys Identified Mail option will be activated by default for any domain name that you register under your website hosting account, so you won’t need to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX records (so that the emails related to this domain will be handled by our cloud platform), a private encryption key will be issued instantly on our mail servers and a TXT resource record with a public key will be sent to the Domain Name System. All addresses set up with this domain will be protected by DomainKeys Identified Mail, so if you send emails such as periodic newsletters, they will reach their target destination and the receivers will know that the messages are legitimate, because the DKIM functionality makes it impossible for unsolicited individuals to forge your e-mail addresses.
