DomainKeys Identified Mail (DKIM) is an authentication system used to verify that an e-mail message has been sent by an authenticated server or person. A digital signature is added to the header of the message using a private cryptographic key. When the message is received, a public key that is available in the global DNS database is used to validate who actually sent it and if the content has been modified in some way. The chief job of DomainKeys Identified Mail is to avert the widely spread scam and spam 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 or financial institution, for example, but the signature doesn’t correspond, you will either not get the email message at all, or you will get it with a notification that most probably it’s not a legitimate one. It depends on mail service providers what exactly will happen with an email which fails the signature check. DomainKeys Identified Mail will also supply you with an added security layer when you communicate with your business allies, for instance, as they can see that all the email messages that you send are genuine and haven’t been meddled with in the meantime.
DomainKeys Identified Mail in Web Hosting
When you buy any of the Linux web hosting that we offer, the DomainKeys Identified Mail feature will be enabled by default for any domain name that you add to your shard hosting account, so you won’t have to create any records or to activate anything manually. When a domain is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain will be handled by our cloud platform), a private key will be generated momentarily on our mail servers and a TXT record with a public key will be sent to the DNS system. All addresses created using this domain will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target destination and the receivers will be sure that they are authentic, since the DKIM feature makes it impossible for unsolicited parties to spoof your e-mail addresses.
