DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an e-mail has been sent by an authorized person or server. A digital signature is attached to the header of the email using a private key. When the email is received, a public key that’s available in the global Domain Name System is used to confirm who actually sent it and if the content has been altered in any way. The prime purpose of DomainKeys Identified Mail is to block the widespread spam and scam messages, as it makes it impossible to forge 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 warning that most likely it’s not a legitimate one. It depends on mail service providers what exactly will happen with an email which fails to pass the signature examination. DKIM will also supply you with an extra safety layer when you communicate with your business partners, for instance, since they can see that all the e-mail messages that you exchange are legitimate and have not been manipulated on their way.

DomainKeys Identified Mail in Cloud Web Hosting

When you buy one of the cloud web hosting that we offer, the DomainKeys Identified Mail feature will be enabled as standard for any domain name that you add to your account, so you won’t have to create any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX records (so that the email messages associated with this domain will be handled by our cloud hosting platform), a private key will be generated straight away on our email servers and a TXT record with a public key will be sent to the Domain Name System. All email addresses created using this domain name will be protected by DomainKeys Identified Mail, so if you send emails such as periodic newsletters, they will reach their target audience and the receivers will know that they are legitimate, as the DKIM option makes it impossible for unauthorized parties to forge your e-mail addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DomainKeys Identified Mail activated by default, so if you choose a semi-dedicated hosting plan and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the authentication system will be created automatically – a private encryption key on our email servers for the e-signature and a TXT resource record carrying the public key for the global Domain Name System. Since the protection is set up for a certain domain name, all e-mail addresses created under it will have a signature, so you will not need to worry that the emails that you send out may not reach their destination address or that somebody may fake any of your email addresses and attempt to scam/spam people. This may be rather essential in case you use email communication in your business, since your associates and/or customers will be able to distinguish authentic emails from counterfeit ones.
