DomainKeys Identified Mail (DKIM) is a validation system used to prove that an e-mail message has been sent by an authenticated server or individual. An electronic signature is attached to the email’s header using a private cryptographic key. When the email is received, a public key that is available in the global Domain Name System is used to validate who actually sent it and if its content has been modified in some way. The chief job of DKIM is to block the widespread spam and scam messages, as it makes it impossible to forge 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 doesn’t match, you will either not get the email message at all, or you will receive it with a warning that most likely it is not a genuine one. It depends on mail service providers what exactly will happen with an email message that fails to pass the signature examination. DKIM will also provide you with an added layer of protection when you communicate with your business allies, for example, since they can see for themselves that all the emails that you send are legitimate and have not been manipulated in the meantime.
DomainKeys Identified Mail in Shared Hosting
The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a shared hosting account on our cloud website hosting platform, so you will not need to do anything yourself to turn it on. The only requirement is that the given domain should be hosted in an account on our platform using our MX and NS records, so that the email messages will go through our mail servers. The private encryption 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 will not need to do anything manually on your end in order to enable this option. The DKIM email validation system will allow you to send trustworthy emails, so if you are sending a newsletter or offers to clients, for instance, your emails will always reach their target audience, whereas unauthorized 3rd parties will not be able to spoof your email addresses.
