DomainKeys Identified Mail (DKIM) is an email authentication system used to certify that an e-mail has been sent by an authenticated mail server or individual. An electronic signature is added to the header of the 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 confirm who actually sent it and whether the content has been changed in any way. The essential purpose of DKIM is to impede the widely spread scam and spam messages, 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 does not correspond, you will either not receive the email message at all, or you will get it with a warning note that most likely it’s not genuine. It depends on email service providers what exactly will happen with an email message that fails the signature test. DKIM will also give you an extra safety layer when you communicate with your business partners, for example, since they can see for themselves that all the email messages that you send are legitimate and haven’t been tampered with on their way.

DomainKeys Identified Mail in Website Hosting

When you purchase any of the website hosting that we offer, the DomainKeys Identified Mail option will be activated as standard for any domain name that you register under your shared website hosting account, so you won’t need to set up 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 associated with 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 global Domain Name System. All email addresses set up with this domain will be protected by DKIM, so if you send email messages such as regular newsletters, they will reach their target audience and the receivers will be sure that the messages are genuine, because the DKIM option makes it impossible for unsolicited people to spoof your e-mail addresses.
