DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an email message has been sent by an authenticated individual or mail server. A digital signature is added to the header of the message by using a private encryption key. When the email message is received, a public key that’s available in the global Domain Name System is used to validate who exactly sent it and whether the content has been edited in some way. The principal function of DomainKeys Identified Mail is to block the widely spread spam and scam 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 example, but the signature does not correspond, you will either not receive the email at all, or you will receive it with a notification that most probably it is not an authentic one. It depends on email service providers what exactly will happen with an email message that fails to pass the signature test. DKIM will also give you an added protection layer when you communicate with your business associates, for example, since they can see that all the emails that you send are genuine and haven’t been modified in the meantime.

DomainKeys Identified Mail in Cloud Website Hosting

You’ll be able to take advantage of DomainKeys Identified Mail with each Linux cloud website hosting that we’re offering without needing to do anything specific, as the mandatory records for using this email authentication system are created automatically by our web hosting platform when you add a domain name to an existing web hosting account via the Hepsia Control Panel. As long as the specific domain name uses our name server records, a private cryptographic key will be issued and kept on our mail servers and a TXT record with a public key will be sent to the global DNS system. In case you send periodic emails to clients or business collaborators, they will always be received and no unauthorized person will be able to spoof your address and make it look like you’ve sent a particular email message.
