DomainKeys Identified Mail, or DKIM, is a system for confirming the authenticity of an email using an e-signature. When DKIM is enabled for a particular 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 email message is sent, a signature is generated using the private key and when the email message is received, the signature is checked by the POP3/IMAP mail server using the public key. In this way, the recipient can easily tell if the email is authentic or if the sender’s address has been forged. A mismatch will appear if the content of the email message has been changed in the meantime as well, so DKIM can also be used to make sure that the sent and the received emails are identical and that nothing has been added or removed. This authentication system will increase your email security, since you can verify the authenticity of the important email messages that you get and your colleagues can do the same with the email messages that you send them. Depending on the given email service provider’s policy, an email that fails the test may be erased or may be delivered to the recipient’s mailbox with a warning alert.
DomainKeys Identified Mail in Shared Web Hosting
If you host a domain in a shared web hosting account from our company, all the obligatory records for using the DomainKeys Identified Mail feature will be created 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 encryption key will be created on our email servers, whereas a public key will be published to the DNS database automatically using the TXT resource record. Thus, you won’t have to do anything manually and you’ll be able to take advantage of all the benefits of this authentication system – your messages will be sent to any target destination without being disallowed and no one will be able to send email messages forging your email addresses. The latter is truly important if the essence of your online presence suggests sending periodic offers or newsletters via email to prospective and existing customers.
DomainKeys Identified Mail in Semi-dedicated Servers
All compulsory DomainKeys Identified Mail records will be created automatically by our cloud platform when you add a domain name as hosted in your semi-dedicated server account, so in case you decide to purchase a semi-dedicated plan, you will not need to set up anything to be able to take advantage of the email validation system. The domain name should use our name servers in order for its DNS resource records to be managed by us and as long as this precondition is fulfilled, a private key will be created on our email servers and a public key will be added to the global DNS database by a special TXT resource record. All addresses that you create with the domain name will be protected by DKIM, which will make it impossible for 3rd parties to spoof any email address. Both you and your partners or customers can benefit from this feature, as it will guarantee a much higher security level for your online communication.
