DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email using an e-signature. When DKIM is activated for a specific domain name, a public encryption key is published to the global DNS database and a private one is kept on the email server. If a new email message is sent, a signature is issued using the private key and when the email message is received, the signature is validated by the incoming POP3/IMAP email server using the public key. Thus, the receiver can easily discern if the message is legitimate or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email has been modified on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or deleted. This email authentication system will boost your email security, as you can confirm the legitimacy of the important email messages that you receive and your colleagues can do the same with the email messages that you send them. Depending on the given mail service provider’s policy, an email that fails the check may be deleted or may show up in the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Website Hosting

If you order any of the Linux website hosting packages that we’re offering, the DomainKeys Identified Mail functionality will be enabled by default for any domain that you register under your web hosting account, so you won’t need to set up any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our NS and MX resource records (so that the email messages related to this domain will be handled by our cloud web hosting platform), a private cryptographic key will be issued right away on our email servers and a TXT resource record with a public key will be sent to the global DNS database. All addresses set up using this domain will be protected by DKIM, so if you send emails such as regular newsletters, they will reach their target destination and the recipients will be sure that the messages are genuine, because the DKIM option makes it impossible for unsolicited persons to spoof your addresses.
