DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an email has been sent by an authenticated individual or email server. An e-signature is attached to the header of the message using a private key. When the email is received, a public key that’s available in the global DNS database is used to verify who actually sent it and if its content has been changed in any way. The principal task of DomainKeys Identified Mail is to impede the widespread scam and spam 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 example, but the signature doesn’t match, you will either not get the email message at all, or you will receive it with a notification that most probably it is not genuine. It depends on email providers what exactly will happen with an email message which fails to pass the signature check. DomainKeys Identified Mail will also offer you an additional layer of security when you communicate with your business associates, for instance, as they can see that all the email messages that you send are legitimate and haven’t been tampered with on their way.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail feature is activated by default for all domain names that are hosted in a web hosting account on our cloud website hosting platform, so you won’t have to do anything on your end to turn it on. The only requirement is that the particular domain name should be hosted in an account on our platform using our MX and NS records, so that the emails will go through our mail servers. The private key will be created on the server and the TXT resource record, which includes 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 authentication system will allow you to send out trustworthy e-mails, so if you’re sending offers or a newsletter to clients, for instance, your email messages will always reach their target destination, whereas unauthorized third parties will not be able to spoof your email addresses.
