DomainKeys Identified Mail (DKIM) is an authentication system used to check that an e-mail message has been sent by an authenticated individual or email server. A digital signature is added to the header of the email message using a private key. When the email message is received, a public key that’s available in the global DNS database is used to validate who actually sent it and if the content has been modified in any way. The prime purpose of DomainKeys Identified Mail is to hamper the widely spread spam and scam 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 match, you will either not receive the message at all, or you’ll get it with a warning alert that most probably it’s not authentic. It depends on email service providers what exactly will happen with an email message that fails to pass the signature examination. DKIM will also provide you with an additional layer of safety when you communicate with your business associates, for instance, since they can see for themselves that all the e-mails that you exchange are authentic and haven’t been meddled with in the meantime.

DomainKeys Identified Mail in Cloud Hosting

When you buy one of the Linux cloud hosting that we are offering, the DomainKeys Identified Mail option will be activated by default for any domain name that you add to your web hosting account, so you won’t have to create any records or to do anything manually. When a domain name is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS resource records (so that the emails related to this domain will be handled by our cloud web hosting platform), a private key will be generated immediately on our email 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 name will be protected by DomainKeys Identified Mail, so if you send email messages such as periodic newsletters, they will reach their target audience and the receivers will know that the messages are authentic, because the DKIM functionality makes it impossible for unauthorized people to spoof your e-mail addresses.
