DomainKeys Identified Mail, or DKIM, is a method for confirming the genuineness of an email by using a digital signature. When DKIM is activated for a particular domain, a public encryption key is published to the global DNS system and a private one is kept on the email server. If a new email is sent, a signature is generated using the private key and when the message is received, that signature is verified by the incoming POP3/IMAP mail server using the public key. In this way, the recipient can easily discern if the message is legitimate or if the sender’s address has been spoofed. A discrepancy 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 delivered messages are identical and that nothing has been added or deleted. This email authentication system will strengthen your email security, since you can verify the genuineness of the important email messages that you receive and your partners can do the exact same thing with the emails that you send them. Based on the given mail service provider’s policies, an email that fails the test may be erased or may appear in the recipient’s inbox with a warning sign.

DomainKeys Identified Mail in Cloud Web Hosting

If you host a domain in a cloud web hosting account from us, all the necessary records for using the DomainKeys Identified Mail functionality will be created by default. This will happen the moment you add the domain in the Hosted Domains section of the Hepsia Control Panel, as long as it also uses our NS records. A private cryptographic key will be generated on our email servers, whereas 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 will be able to take advantage of all the benefits of this authentication system – your messages will be delivered to any destination without being disallowed and nobody will be able to send messages forging your e-mail addresses. The latter is truly important if the type of your web presence suggests sending periodic newsletters or offers via email to prospective and existing customers.
