DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an email message has been sent by an authenticated server or person. An e-signature is attached to the header of the email using a private key. When the email message is received, a public key that is available in the global DNS database is used to check who actually sent it and if its content has been changed in some way. The essential function of DKIM is to avert the widely spread spam and scam email messages, as it makes it impossible to forge an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for example, but the signature doesn’t correspond, you will either not receive the message at all, or you will get it with a warning note that most probably it is not a genuine one. It depends on mail service providers what exactly will happen with an email message which fails to pass the signature examination. DomainKeys Identified Mail will also give you an additional layer of security when you communicate with your business partners, for instance, since they can see for themselves that all the email messages that you exchange are genuine and haven’t been meddled with in the meantime.
DomainKeys Identified Mail in Cloud Hosting
If you get one of the cloud hosting that we’re offering, the DomainKeys Identified Mail feature will be enabled by default for any domain that you add to your web hosting account, so you won’t need to set up 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 emails associated with this domain name will be handled by our cloud web hosting platform), a private cryptographic key will be issued instantaneously on our email servers and a TXT record with a public key will be sent to the Domain Name System. All email addresses set up with this domain will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target destination and the receivers will know that the messages are legitimate, as the DKIM option makes it impossible for unauthorized individuals to forge your email addresses.
