DomainKeys Identified Mail, or DKIM, is a system for verifying the legitimacy of an email using an e-signature. When DKIM is enabled for a given domain name, a public cryptographic key is published to the global Domain Name System and a private one is stored on the mail server. When a new message is sent, a signature is issued using the private key and when the email message is delivered, that signature is validated by the POP3/IMAP email server using the public key. Thus, the recipient can easily know if the message is authentic or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email message has been modified on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received messages are identical and that nothing has been added or deleted. This authentication system will boost your email security, as you can validate the genuineness of the important emails that you get and your associates can do the exact same thing with the messages that you send them. Depending on the particular mail service provider’s adopted policy, a message that fails the check may be removed or may show up in the receiver’s inbox with a warning symbol.
DomainKeys Identified Mail in Cloud Hosting
The DomainKeys Identified Mail feature is activated by default for all domain names that are hosted in a cloud hosting account on our cloud web hosting platform, so you will not have to do anything on your end to activate it. The only requirement is that the particular domain name should be hosted in a hosting account on our platform using our MX and NS records, so that the email messages will go through our mail servers. The private encryption key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global DNS database automatically, so you won’t have to do anything manually on your end in order to activate this option. The DKIM authentication system will permit you to send trustable email messages, so if you are sending offers or a newsletter to clients, for instance, your emails will always reach their target viewers, while unauthorized 3rd parties will not be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
All obligatory DKIM records will be set up automatically by our cloud hosting platform when you add a domain name as hosted in your semi-dedicated server account, so if you decide to purchase a semi-dedicated server plan, you will not need to set up anything to be able to use the email authentication system. The domain name should use our name servers in order for its DNS resource records to be managed by us and if this condition is matched, a private encryption key will be generated on our email servers and a public key will be sent to the global Domain Name System by a special TXT record. All addresses that you create using the domain name will be protected by DKIM, which will make it impossible for third parties to fake any address. Both you and your associates or clients can take advantage of this functionality, since it will ensure a much higher security level for your e-correspondence.
