DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an e-mail message has been sent by an authenticated server or individual. A digital signature is added to the header of the email using a private encryption key. When the message is received, a public key that is available in the global DNS database is used to confirm who exactly sent it and if the content has been modified in some way. The fundamental purpose of DomainKeys Identified Mail is to avert the widespread scam and spam emails, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank, for example, but the signature does not correspond, you will either not get the message at all, or you will receive it with an alert that most likely it is not a genuine one. It depends on email providers what exactly will happen with an email that fails to pass the signature check. DKIM will also supply you with an additional security layer when you communicate with your business allies, for example, as they can see for themselves that all the emails that you send are legitimate and have not been meddled with on their way.
DomainKeys Identified Mail in Cloud Hosting
If you order one of the Linux cloud hosting that we are offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you register under your shard hosting account, so you won’t need to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS resource records (so that the emails related to this domain name will be handled by our cloud platform), a private cryptographic key will be generated momentarily on our email servers and a TXT resource record with a public key will be sent to the Domain Name System. All email addresses set up with this domain name will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target audience and the recipients will be sure that the messages are authentic, as the DKIM option makes it impossible for unsolicited people to spoof your email addresses.
