DomainKeys Identified Mail (DKIM) is an authentication system used to check that an email message has been sent by an authorized individual or server. A digital signature is attached to the message’s header by using a private key. When the email is received, a public key that’s available in the global DNS database is used to validate who actually sent it and if its content has been altered in some way. The prime job of DomainKeys Identified Mail is to hinder the widely spread scam and spam emails, as it makes it impossible to fake an email address. If a message is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature does not correspond, you will either not get the message at all, or you’ll get it with a notification that most probably it’s not an authentic one. It depends on email providers what exactly will happen with an email message which fails to pass the signature examination. DKIM will also offer you an additional layer of protection when you communicate with your business allies, for example, since they can see that all the e-mail messages that you exchange are legitimate and have not been modified in the meantime.

DomainKeys Identified Mail in Hosting

The DomainKeys Identified Mail feature is pre-enabled for all domain names that are hosted in a hosting account on our cloud platform, so you won’t have to do anything yourself to activate it. The sole condition is that the particular domain name should be hosted in a web hosting account on our end using our MX and NS resource records, so that the emails will go through our email servers. The private key will be generated on the server and the TXT record, which includes the public key, will be published to the global DNS system automatically, so you won’t have to do anything manually on your end in order to enable this feature. The DKIM authentication system will allow you to send credible messages, so if you are sending offers or a newsletter to customers, for instance, your email messages will always reach their target destination, while unauthorized third parties will not be able to spoof your email addresses.
