DomainKeys Identified Mail (DKIM) is an authentication system used to confirm that an email has been sent by an authenticated mail server or individual. A digital signature is added to the header of the message by using a private key. When the email is received, a public key that is available in the global Domain Name System is used to check who actually sent it and whether the content has been edited in any way. The chief purpose of DKIM is to block the widespread scam and spam emails, as it makes it impossible to fake an email address. If an email message is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not receive the email message at all, or you will receive it with a warning that most probably it’s not legitimate. It depends on mail service providers what exactly will happen with an email which fails the signature test. DKIM will also offer you an added safety layer when you communicate with your business partners, for example, since they can see for themselves that all the e-mail messages that you exchange are legitimate and have not been tampered with in the meantime.

DomainKeys Identified Mail in Cloud Website Hosting

The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a cloud website hosting account on our cloud web hosting platform, so you won’t need to do anything on your end to activate it. The sole requirement is that the given domain 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 encryption key will be generated on the server and the TXT record, which contains the public key, will be published to the global DNS system automatically, so you won’t have to do anything manually on your end in order to activate this functionality. The DKIM validation system will permit you to send trustable email messages, so if you are sending offers or a newsletter to customers, for example, your email messages will always reach their target audience, while unsolicited third parties won’t be able to forge your email addresses.
