DomainKeys Identified Mail, or DKIM, is a system for checking the genuineness of an email by using an electronic signature. When DKIM is enabled for a certain domain, a public key is published to the global Domain Name System and a private one is kept on the email server. When a new email message is sent, a signature is issued using the private key and when the message is delivered, that signature is ‘scanned’ by the incoming POP3/IMAP mail server using the public key. In this way, the receiver can easily distinguish if the email is authentic or if the sender’s email address has been spoofed. A discrepancy will occur if the content of the email message has been edited in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered messages are identical and that nothing has been added or erased. This email validation system will enhance your email safety, since you can verify the legitimacy of the important emails that you receive and your partners can do likewise with the email messages that you send them. Depending on the particular mail service provider’s adopted policies, an email that fails to pass the check may be erased or may end up in the recipient’s inbox with a warning sign.

DomainKeys Identified Mail in Shared Hosting

If you order any of the shared hosting that we’re offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you add to your shared web 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 in-house developed Hepsia Control Panel using our NS and MX resource records (so that the emails related to this domain name will be handled by our cloud platform), a private cryptographic key will be created momentarily on our mail servers and a TXT record with a public key will be sent to the global DNS database. All email addresses set up using this domain name will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target destination and the receivers will be sure that the messages are genuine, since the DomainKeys Identified Mail feature makes it impossible for unsolicited individuals to forge your email addresses.
