DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an email has been sent by an authenticated server or individual. A digital signature is added to the header of the message by using a private encryption key. When the message is received, a public key that’s available in the global Domain Name System is used to confirm who actually sent it and whether its content has been changed in any way. The fundamental job of DKIM is to stop the widespread scam and spam email messages, as it makes it impossible to fake an email address. If a message is sent from an email address claiming to belong to your bank, for example, but the signature doesn’t correspond, you will either not get the message at all, or you’ll get it with a notification that most probably it is not authentic. It depends on mail service providers what exactly will happen with an email which fails to pass the signature test. DomainKeys Identified Mail will also give you an additional layer of protection when you communicate with your business partners, for instance, as they can see that all the e-mails that you exchange are authentic and have not been meddled with in the meantime.

DomainKeys Identified Mail in Shared Web Hosting

If you order any of the Linux shared web hosting packages that we’re offering, the DomainKeys Identified Mail option will be enabled as standard for any domain that you register under your shared account, so you won’t need to set up any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain name will be handled by our cloud hosting platform), a private cryptographic key will be generated right away on our mail servers and a TXT resource record with a public key will be sent to the DNS system. All addresses set up using this domain name will be protected by DomainKeys Identified Mail, so if you send email messages such as regular newsletters, they will reach their target audience and the recipients will know that the messages are genuine, since the DKIM feature makes it impossible for unauthorized people to spoof your e-mail addresses.
