DomainKeys Identified Mail, or DKIM, is a method for validating the genuineness of an email by using an electronic signature. When DKIM is enabled for a certain domain name, a public cryptographic key is published to the global DNS system and a private one is stored on the email server. When a new email message is sent, a signature is issued using the private key and when the email message is delivered, that signature is validated by the incoming POP3/IMAP server using the public key. Thus, the recipient can easily recognize if the message is authentic or if the sender’s email address has been spoofed. A discrepancy will appear 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 received email messages are identical and that nothing has been added or deleted. This validation system will heighten your email safety, since you can confirm the genuineness of the important emails that you receive and your colleagues can do the same with the messages that you send them. Based on the particular email service provider’s policies, an email that fails to pass the check may be erased or may show up in the recipient’s inbox with a warning alert.
DomainKeys Identified Mail in Hosting
If you host a domain in a hosting account with our company, all the obligatory records for using the DomainKeys Identified Mail option will be added by default. This will happen the moment you add the domain name in , as long as your domain also uses our NS records. A private key will be generated on our email servers, while a public key will be added to the global Domain Name System automatically using the TXT record. In this way, you will not need to do anything manually and you’ll be able to make use of all the benefits of this email validation system – your emails will be delivered to any destination without being disallowed and no one will be able to send out email messages forging your email addresses. The latter is quite important if the type of your worldwide web presence involves sending out regular newsletters or offers via email to prospective and current customers.
DomainKeys Identified Mail in Semi-dedicated Servers
All mandatory DomainKeys Identified Mail records will be set up automatically by our cloud web hosting platform when you add a domain as hosted in a semi-dedicated server account, so if you decide to order a semi-dedicated hosting package, you will not need to set up anything to be able to take advantage of the email authentication system. The domain name should use our name servers in order for its DNS resource records to be managed by our company and as long as this requirement is matched, a private cryptographic key will be generated on our mail servers and a public key will be added to the DNS database by a special TXT record. All addresses that you create with the domain will be protected by DKIM, which will make it impossible for third parties to forge any address. Both you and your associates or clients can take advantage of this option, as it will guarantee a much higher protection level for your online correspondence.
