DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an e-mail message has been sent by an authorized mail server or person. An electronic signature is attached to the header of the email using a private encryption key. When the email is received, a public key that’s available in the global Domain Name System is used to confirm who actually sent it and whether the content has been modified in any way. The principal purpose of DKIM is to hamper the widely spread spam and scam email messages, 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, for instance, but the signature does not correspond, you will either not receive the email at all, or you’ll get it with a warning that most probably it’s not a genuine one. It depends on mail service providers what exactly will happen with an email that fails to pass the signature test. DomainKeys Identified Mail will also offer you an added layer of safety when you communicate with your business allies, for example, since they can see that all the emails that you exchange are legitimate and have not been modified on their way.

DomainKeys Identified Mail in Shared Website Hosting

The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a shared website hosting account on our cloud website hosting platform, so you will not have to do anything yourself to turn it on. The only requirement is that the given domain name should be hosted in a website hosting account on our end using our NS and MX resource records, so that the email messages will go through our mail servers. The private key will be generated on the server and the TXT resource record, which includes 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 validation system will allow you to send out trustable emails, so if you’re sending offers or a newsletter to clients, for instance, your emails will always reach their target viewers, while unauthorized third parties will not be able to spoof your email addresses.
