DomainKeys Identified Mail (DKIM) is an email validation system used to prove that an e-mail has been sent by an authorized individual or email server. An e-signature is added to the header of the email by using a private key. When the email message is received, a public key that’s available in the global DNS database is used to check who exactly sent it and whether its content has been altered in some way. The prime task of DomainKeys Identified Mail is to obstruct the widespread spam and scam emails, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank, for example, but the signature does not match, you will either not get the message at all, or you’ll get it with a warning that most probably it’s not legitimate. It depends on email providers what exactly will happen with an email message which fails the signature check. DKIM will also supply you with an extra layer of security when you communicate with your business partners, for instance, since they can see for themselves that all the messages that you exchange are genuine and haven’t been meddled with on their way.

DomainKeys Identified Mail in Cloud Hosting

If you order any of the Linux cloud hosting that we offer, the DomainKeys Identified Mail feature will be enabled as standard for any domain that you add to your shard hosting account, so you will not have to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our NS and MX records (so that the email messages related to this domain will be handled by our cloud platform), a private encryption key will be created straight away on our email servers and a TXT resource record with a public key will be sent to the global Domain Name System. All addresses created with this domain name will be protected by DomainKeys Identified Mail, so if you send out emails such as periodic newsletters, they will reach their target destination and the recipients will know that the messages are authentic, because the DKIM functionality makes it impossible for unsolicited parties to forge your e-mail addresses.
