DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an email message has been sent by an authenticated email server or person. A digital signature is added to the header of the email using a private key. When the message is received, a public key that is available in the global DNS database is used to validate who exactly sent it and whether its content has been edited in some way. The fundamental function of DomainKeys Identified Mail is to obstruct the widespread scam and spam 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 instance, but the signature does not match, you will either not get the message at all, or you’ll get it with an alert that most likely it is not authentic. It depends on mail service providers what exactly will happen with an email which fails to pass the signature test. DKIM will also give you an additional layer of safety when you communicate with your business allies, for example, since they can see for themselves that all the e-mails that you exchange are authentic and have not been tampered with on their way.
DomainKeys Identified Mail in Cloud Website Hosting
In case you host a domain in a cloud website hosting account from us, all the mandatory records for using the DomainKeys Identified Mail feature will be added by default. This will happen the moment you add the domain name in the Control Panel’s Hosted Domains section, as long as your domain also uses our NS records. A private encryption key will be generated on our email servers, whereas a public key will be sent to the Domain Name System automatically using the TXT resource record. In this way, you will not need to do anything manually and you’ll be able to make use of all the benefits of this email validation system – your email messages will be delivered to any target audience without being denied and no one will be able to send out emails forging your addresses. The latter is very important in case the essence of your Internet presence involves sending out regular offers or newsletters via email to prospective and current customers.
