DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an e-mail has been sent by an authorized server or individual. An electronic signature is attached to the email’s header by using a private encryption key. When the email is received, a public key that’s available in the global DNS database is used to confirm who actually sent it and if its content has been edited in any way. The chief function of DKIM is to stop the widespread spam and scam emails, as it makes it impossible to fake an email address. If an email is sent from an address claiming to belong to your bank, for instance, but the signature does not correspond, you will either not get the email message at all, or you’ll receive it with a warning notice that most likely it’s not legitimate. It depends on email providers what exactly will happen with an email message that fails the signature check. DKIM will also supply you with an additional layer of security when you communicate with your business partners, for example, as they can see that all the e-mail messages that you exchange are legitimate and have not been manipulated in the meantime.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail feature is activated by default for all domain names that are hosted in a shared hosting account on our cloud servers, so you won’t have to do anything on your end to turn it on. The only condition is that the given domain should be hosted in a web hosting account on our platform using our MX and NS resource records, so that the email messages will go through our mail servers. The private cryptographic key will be generated on the server and the TXT resource record, which contains the public key, will be published to the global Domain Name System automatically, so you will not have to do anything manually on your end in order to activate this feature. The DomainKeys Identified Mail validation system will allow you to send trustworthy emails, so if you are sending offers or a newsletter to clients, for example, your email messages will always reach their target viewers, whereas unsolicited 3rd parties will not be able to spoof your email addresses.
