DomainKeys Identified Mail
DomainKeys Identified Mail (DKIM) - find out more about it, what it does, how it works and how to activate it for your mailboxes.
DomainKeys Identified Mail (DKIM) is a validation system used to confirm that an email message has been sent by an authorized individual or mail server. An electronic signature is attached to the header of the message using a private encryption key. When the email message is received, a public key that’s available in the global DNS database is used to check who actually sent it and if its content has been modified in any way. The main purpose of DKIM is to hinder the widely spread spam and scam emails, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for example, but the signature doesn’t match, you will either not receive the email message at all, or you will receive it with an alert that most likely it is not a legitimate one. It depends on email service providers what exactly will happen with an email that fails to pass the signature examination. DomainKeys Identified Mail will also provide you with an additional layer of protection when you communicate with your business associates, for example, as they can see for themselves that all the messages that you exchange are legitimate and have not been tampered with in the meantime.
DomainKeys Identified Mail in Cloud Web Hosting
When you buy any of the Linux cloud web hosting packages that we offer, the DomainKeys Identified Mail feature will be enabled as standard for any domain that you register under your website hosting account, so you will not need to create any records or to enable anything manually. When a domain is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our MX and NS records (so that the email messages related to this domain will be handled by our cloud platform), a private cryptographic key will be created immediately on our email servers and a TXT record with a public key will be sent to the global Domain Name System. All addresses created using this domain will be protected by DomainKeys Identified Mail, so if you send email messages such as periodic newsletters, they will reach their target destination and the receivers will know that they are genuine, since the DomainKeys Identified Mail option makes it impossible for unauthorized people to spoof your e-mail addresses.
