DomainKeys Identified Mail (DKIM) is a validation system used to check that an e-mail message has been sent by an authenticated person or mail server. An electronic signature is added to the message’s header by using a private cryptographic key. When the message is received, a public key that is available in the global DNS database is used to validate who exactly sent it and if the content has been changed in any way. The essential function of DKIM is to impede the widely spread scam and spam emails, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not get the email at all, or you will get it with a notification that most likely it’s not an authentic one. It depends on email providers what exactly will happen with an email message that fails the signature examination. DomainKeys Identified Mail will also provide you with an additional layer of safety when you communicate with your business associates, for instance, since they can see that all the messages that you send are authentic and haven’t been tampered with on their way.

DomainKeys Identified Mail in Website Hosting

The DomainKeys Identified Mail option is activated by default for all domains that are hosted in a website hosting account on our cloud website hosting platform, so you won’t have to do anything yourself to enable it. The sole requirement is that the particular domain name should be hosted in a hosting account on our platform using our NS and MX resource records, so that the e-mails will go through our email servers. The private encryption key will be created on the server and the TXT resource record, which includes the public key, will be published to the DNS database automatically, so you won’t need to do anything manually on your end in order to enable this option. The DomainKeys Identified Mail email authentication system will permit you to send out trustable e-mail messages, so if you’re sending a newsletter or offers to customers, for instance, your email messages will always reach their target viewers, whereas unauthorized third parties won’t be able to forge your email addresses.
