DomainKeys Identified Mail, or DKIM, is a method for validating the genuineness of an email using a digital signature. When DomainKeys Identified Mail is activated for a given domain, a public encryption key is published to the global DNS database 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 received, that signature is checked by the incoming POP3/IMAP server using the public key. Thus, the recipient can easily recognize if the message is genuine or if the sender’s address has been spoofed. A mismatch will occur if the content of the email 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 attached or erased. This email authentication system will boost your email security, as you can confirm the legitimacy of the important emails that you receive and your associates can do the same with the email messages that you send them. Depending on the given email service provider’s policy, a message that fails the test may be deleted or may show up in the receiver’s inbox with a warning sign.

DomainKeys Identified Mail in Cloud Website Hosting

In case you host a domain in a cloud website hosting account with our company, all the compulsory records for using the DomainKeys Identified Mail option will be added by default. This will happen the moment you add the domain name in the Hosted Domains section of the Hepsia Control Panel, as long as it also uses our NS resource records. A private key will be created on our email servers, while a public key will be added to the DNS system automatically by using the TXT record. Thus, you won’t need to do anything manually and you’ll be able to take full advantage of all the benefits of this email validation system – your email messages will be sent to any audience without being denied and nobody will be able to send messages forging your addresses. The latter is truly important in case the type of your worldwide web presence suggests sending out periodic newsletters or offers via email to potential and existing customers.
