DomainKeys Identified Mail, or DKIM, is a system for confirming the genuineness of an email by using an electronic signature. When DomainKeys Identified Mail 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 email server. If a new message is sent, a signature is issued using the private key and when the email message is received, the signature is ‘scanned’ by the POP3/IMAP mail server using the public key. Thus, the recipient can easily know if the email message is genuine or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email has been changed in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered emails are identical and that nothing has been added or removed. This authentication system will strengthen your email safety, as you can verify the legitimacy of the important email messages that you receive and your colleagues can do the same with the emails that you send them. Depending on the given mail service provider’s policy, an email that fails the check may be erased or may be delivered to the recipient’s mailbox with a warning symbol.
DomainKeys Identified Mail in Shared Hosting
In case you host a domain name in a shared hosting account with our company, all the compulsory records for using the DomainKeys Identified Mail option will be set up by default. This will happen once you add the domain in the Control Panel’s Hosted Domains section, on the condition that it also uses our NS resource records. A private encryption key will be created on our email servers, while a public key will be published to the DNS database automatically using the TXT record. In this way, you will not have to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your emails will be delivered to any destination without being denied and nobody will be able to send email messages faking your e-mail addresses. The latter is pretty important if the essence of your online presence suggests sending out periodic newsletters or offers via email to potential and existing clients.
