DomainKeys Identified Mail (DKIM) is an email validation system used to check that an email message has been sent by an authorized individual or mail server. An electronic signature is added to the message’s header using a private encryption key. When the message is received, a public key that’s available in the global DNS database is used to confirm who exactly sent it and whether its content has been modified in any way. The primary function of DKIM is to hinder the widely spread spam and scam email messages, as it makes it impossible to fake an email address. If an email message is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t match, you will either not get the email at all, or you will get it with an alert that most probably it is not a genuine one. It depends on email providers what exactly will happen with an email message that fails to pass the signature examination. DomainKeys Identified Mail will also provide you with an added layer of protection when you communicate with your business partners, for instance, since they can see that all the e-mail messages that you send are authentic and have not been meddled with on their way.
DomainKeys Identified Mail in Web Hosting
The DomainKeys Identified Mail feature is activated by default for all domains that are hosted in a web hosting account on our cloud platform, so you won’t have to do anything yourself to activate it. The only condition is that the given domain name should be hosted in an account on our platform using our NS and MX records, so that the e-mail messages will go through our email servers. The private cryptographic key will be generated on the server and the TXT record, which contains the public key, will be published to the global DNS system automatically, so you will not need to do anything manually on your end in order to enable this feature. The DomainKeys Identified Mail validation system will allow you to send trustworthy e-mails, so if you are sending a newsletter or offers to customers, for instance, your emails will always reach their target audience, whereas unauthorized 3rd parties will not be able to forge your email addresses.
