DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an e-mail message has been sent by an authorized email server or person. A digital signature is added to the header of the message by using a private cryptographic key. When the message is received, a public key that’s available in the global DNS database is used to check who actually sent it and if its content has been altered in any way. The fundamental job of DKIM is to avert 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, for example, but the signature doesn’t match, you will either not get the email at all, or you will receive it with a warning that most likely it is 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 extra layer of protection when you communicate with your business allies, for instance, as they can see for themselves that all the emails that you exchange are genuine and haven’t been modified in the meantime.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail functionality is enabled by default for all domain names that are hosted in a web hosting account on our cloud platform, so you will not need to do anything on your end to enable it. The sole condition is that the particular domain should be hosted in a web hosting account on our platform using our MX and NS records, so that the e-mails will go through our mail servers. The private encryption key will be generated on the server and the TXT record, which includes the public key, will be published to the Domain Name System automatically, so you won’t need to do anything manually on your end in order to activate this feature. The DKIM email validation system will permit you to send credible emails, so if you are sending offers or a newsletter to clients, for instance, your emails will always reach their target destination, while unauthorized 3rd parties will not be able to spoof your email addresses.
