DomainKeys Identified Mail, or DKIM, is a method for validating the genuineness of an email by using an electronic signature. When DomainKeys Identified Mail is activated for a given domain, a public key is published to the global DNS database and a private one is kept on the mail server. When a new email message is sent, a signature is generated using the private key and when the email is delivered, the signature is verified by the incoming POP3/IMAP server using the public key. In this way, the recipient can easily tell if the email message is authentic or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email message has been altered in the meantime as well, so DKIM can also be used to ensure that the sent and the received email messages are identical and that nothing has been attached or erased. This validation system will increase your email security, as you can confirm the legitimacy of the important email messages that you get and your colleagues can do likewise with the messages that you send them. Based on the given mail service provider’s adopted policy, an email message that fails the check may be deleted or may show up in the receiver’s inbox with a warning.
DomainKeys Identified Mail in Cloud Website Hosting
If you obtain any of the Linux cloud website hosting that we offer, the DomainKeys Identified Mail option will be activated as standard for any domain that you register under your shared web hosting account, so you won’t need to set up any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our MX and NS records (so that the emails related to this domain name will be handled by our cloud hosting platform), a private encryption key will be generated right away on our mail servers and a TXT record with a public key will be sent to the DNS system. All email addresses created using this domain will be protected by DomainKeys Identified Mail, so if you send email messages such as regular newsletters, they will reach their target audience and the receivers will know that the messages are authentic, as the DKIM option makes it impossible for unsolicited individuals to forge your addresses.
