DomainKeys Identified Mail (DKIM) is an email validation system used to check that an email message has been sent by an authenticated mail server or individual. A digital signature is added to the header of the message 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 if the content has been altered in some way. The essential function of DKIM is to hinder the widespread scam and spam messages, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not match, you will either not receive the email at all, or you’ll receive it with a warning note that most probably it is not legitimate. It depends on mail service providers what exactly will happen with an email message which fails the signature check. DomainKeys Identified Mail will also give you an additional protection layer when you communicate with your business allies, for instance, as they can see for themselves that all the emails that you exchange are legitimate and have not been modified on their way.
DomainKeys Identified Mail in Cloud Hosting
The DomainKeys Identified Mail functionality is pre-activated for all domain names that are hosted in a cloud hosting account on our cloud website hosting platform, so you will not need to do anything on your end to enable it. The only requirement is that the given domain name should be hosted in a web hosting account on our end using our NS and MX records, so that the e-mails will go through our email servers. The private 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 activate this feature. The DomainKeys Identified Mail email authentication system will allow you to send out trustworthy emails, so if you’re sending offers or a newsletter to clients, for example, your email messages will always reach their target audience, whereas unauthorized 3rd parties will not be able to spoof your email addresses.
