DKIM, which is short for DomainKeys Identified Mail, is a validation system, which obstructs email addresses from being forged and email content from being tampered with. This is achieved by attaching an e-signature to every message sent from an address under a certain domain. The signature is created on the basis of a private encryption key that is available on the SMTP server and it can be verified with a public key, which is available in the global DNS database. Thus, any email message with edited content or a forged sender can be spotted by mail service providers. This approach will strengthen your web security dramatically and you’ll be sure that any message sent from a business collaborator, a banking institution, etc., is legitimate. When you send out messages, the receiver will also know for sure that you are indeed the one who has sent them. Any email message that appears to be fraudulent may either be labeled as such or may never appear in the recipient’s mailbox, based on how the given provider has decided to deal with such emails.

DomainKeys Identified Mail in Cloud Hosting

If you buy any of the Linux cloud hosting that we offer, the DomainKeys Identified Mail option will be activated as standard for any domain name that you register under your account, so you won’t need to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our NS and MX resource records (so that the email messages associated with this domain will be handled by our cloud web hosting platform), a private encryption key will be generated instantaneously on our email servers and a TXT resource record with a public key will be sent to the global DNS system. All email addresses created using this domain will be protected by DomainKeys Identified Mail, so if you send out emails such as regular newsletters, they will reach their target audience and the recipients will be sure that the messages are legitimate, since the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to forge your email addresses.
