DomainKeys Identified Mail, or DKIM, is a system for verifying the genuineness of an email by using a digital signature. When DKIM is enabled for a given domain, a public cryptographic key is published to the global DNS system and a private one is kept on the mail server. If a new message is sent, a signature is generated using the private key and when the email message is delivered, the signature is ‘scanned’ by the POP3/IMAP server using the public key. Thus, the receiver can easily know if the email is genuine or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email has been altered on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received messages are identical and that nothing has been attached or removed. This authentication system will strengthen your email security, since you can verify the authenticity of the important emails that you receive and your associates can do the exact same thing with the email messages that you send them. Based on the particular email provider’s adopted policies, an email that fails the examination may be deleted or may show up in the receiver’s mailbox with a warning.

DomainKeys Identified Mail in Shared Web Hosting

If you host a domain in a shared web hosting account with our company, all the compulsory records for using the DomainKeys Identified Mail functionality will be set up by default. This will happen as soon as you add the domain in , on the condition that the domain also uses our NS resource records. A private key will be created on our email servers, while a public key will be sent to the global DNS system automatically using the TXT resource record. Thus, you won’t have to do anything manually and you will be able to make use of all the benefits of this validation system – your email messages will be sent to any target destination without being disallowed and nobody will be able to send messages forging your addresses. The latter is rather important in case the type of your worldwide web presence suggests sending regular offers or newsletters via email to potential and existing customers.
