DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an e-mail has been sent by an authenticated email server or person. A digital signature is added to the header of the email by using a private key. When the message is received, a public key that’s available in the global DNS database is used to verify who actually sent it and whether the content has been altered in some way. The fundamental job of DKIM is to block the widely spread scam and spam emails, as it makes it impossible to fake 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 correspond, you will either not get the message at all, or you’ll get it with an alert that most probably it is not authentic. It depends on email service providers what exactly will happen with an email message which fails the signature check. DKIM will also supply you with an added layer of security when you communicate with your business allies, for example, as they can see that all the emails that you exchange are legitimate and have not been modified in the meantime.
DomainKeys Identified Mail in Web Hosting
The DomainKeys Identified Mail feature is pre-enabled for all domain names that are hosted in a web hosting account on our cloud hosting platform, so you will not have to do anything on your end to enable it. The sole requirement is that the given domain should be hosted in a website hosting account on our platform using our MX and NS records, so that the e-mail messages will go through our mail servers. The private cryptographic key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global Domain Name System automatically, so you won’t need to do anything manually on your end in order to activate this option. The DKIM validation system will permit you to send out trustworthy email messages, so if you are sending a newsletter or offers to clients, for instance, your email messages will always reach their target audience, while unauthorized 3rd parties will not be able to forge your email addresses.
