DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email message using a digital signature. When DKIM is enabled for a specific domain name, a public cryptographic key is published to the global DNS database and a private one is kept on the mail server. When a new email is sent, a signature is generated using the private key and when the email is received, the signature is ‘scanned’ by the incoming POP3/IMAP email server using the public key. Thus, the recipient can easily know if the email message is authentic or if the sender’s email address has been forged. A mismatch will occur if the content of the email message has been altered on its way as well, so DKIM can also be used to make sure that the sent and the received messages are identical and that nothing has been added or removed. This validation system will increase your email safety, since you can verify the genuineness of the important email messages that you get and your colleagues can do the exact same thing with the emails that you send them. Based on the given mail service provider’s policies, a message that fails the examination may be removed or may emerge in the recipient’s inbox with a warning flag.

DomainKeys Identified Mail in Shared Website Hosting

If you purchase one of the Linux shared website hosting packages that we offer, the DomainKeys Identified Mail option will be enabled by default for any domain name 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 name is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX records (so that the emails related to this domain name will be handled by our cloud platform), a private key will be issued immediately on our mail servers and a TXT resource record with a public key will be sent to the global DNS system. All email addresses set up with this domain name will be protected by DomainKeys Identified Mail, so if you send emails such as regular newsletters, they will reach their target destination and the receivers will know that they are genuine, as the DKIM feature makes it impossible for unsolicited persons to forge your e-mail addresses.
