DomainKeys Identified Mail (DKIM) is a validation system used to confirm that an e-mail message has been sent by an authorized individual or email server. An electronic signature is attached to the email’s header using a private cryptographic key. When the email message is received, a public key that’s available in the global Domain Name System is used to check who actually sent it and if its content has been altered in some way. The principal task of DKIM is to avert the widely spread scam and spam messages, 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 example, but the signature does not correspond, you will either not receive the email message at all, or you’ll get it with a warning note that most likely it is not legitimate. It depends on mail service providers what exactly will happen with an email that fails the signature examination. DomainKeys Identified Mail will also offer you an additional layer of protection when you communicate with your business partners, for instance, since they can see that all the e-mail messages that you exchange are authentic and have not been meddled with on their way.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail feature is activated by default for all domains that are hosted in a shared hosting account on our cloud web hosting platform, so you won’t have to do anything on your end to turn it on. The sole condition is that the particular domain name should be hosted in a website hosting account on our platform using our MX and NS resource records, so that the emails will go through our mail servers. The private key will be generated on the server and the TXT resource record, which contains the public key, will be published to the global 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 validation system will enable you to send trustworthy e-mail messages, so if you’re sending offers or a newsletter to clients, for example, your email messages will always reach their target viewers, whereas unauthorized 3rd parties won’t be able to forge your email addresses.
