DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an email message has been sent by an authorized individual or server. A digital signature is added to the header of the message using a private cryptographic key. When the message is received, a public key that is available in the global Domain Name System is used to confirm who exactly sent it and if the content has been modified in any way. The principal function of DKIM is to avert the widespread scam and spam email messages, as it makes it impossible to fake an email address. If an email is sent from an email 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 at all, or you’ll receive it with a warning that most likely it is not authentic. It depends on mail service providers what exactly will happen with an email message which fails the signature test. DomainKeys Identified Mail will also offer you an additional layer of safety when you communicate with your business partners, for example, since they can see that all the e-mails that you send are genuine and have not been manipulated in the meantime.
DomainKeys Identified Mail in Cloud Hosting
The DomainKeys Identified Mail option is pre-enabled for all domain names that are hosted in a cloud hosting account on our cloud platform, so you won’t need to do anything yourself to activate it. The only condition is that the particular domain should be hosted in a website hosting account on our end using our MX and NS records, so that the email messages will go through our email servers. The private encryption key will be created on the server and the TXT resource record, which includes the public key, will be published to the global DNS system automatically, so you will not need to do anything manually on your end in order to activate this option. The DomainKeys Identified Mail authentication system will permit you to send out credible email messages, so if you’re sending offers or a newsletter to customers, for instance, your emails will always reach their target destination, whereas unauthorized third parties won’t be able to spoof your email addresses.
