DomainKeys Identified Mail, or DKIM, is a method for checking the authenticity of an email using an e-signature. When DKIM is enabled for a given domain, a public encryption key is published to the global DNS system and a private one is stored on the mail server. If a new email is sent, a signature is issued using the private key and when the email is received, the signature is validated by the incoming server using the public key. Thus, the receiver can easily recognize if the email message is legitimate or if the sender’s email address has been forged. A mismatch will appear if the content of the email message has been modified on its way as well, so DKIM can also be used to make sure that the sent and the delivered email messages are identical and that nothing has been attached or deleted. This authentication system will enhance your email security, since you can validate the legitimacy of the important email messages that you receive and your partners can do the same with the email messages that you send them. Depending on the particular mail service provider’s adopted policy, a message that fails to pass the check may be deleted or may appear in the receiver’s mailbox with a warning symbol.
DomainKeys Identified Mail in Website Hosting
In case you host a domain name in a website hosting account from our company, all the obligatory records for using the DomainKeys Identified Mail functionality will be added by default. This will happen the moment you add the domain name in , on the condition that it also uses our NS resource records. A private cryptographic key will be created on our email servers, whereas a public key will be published to the DNS system automatically by using the TXT record. Thus, you will not need to do anything manually and you will be able to take advantage of all the benefits of this validation system – your messages will be delivered to any destination without being disallowed and no one will be able to send messages forging your addresses. The latter is very important if the type of your web presence suggests sending out regular offers or newsletters via email to prospective and existing clients.
DomainKeys Identified Mail in Semi-dedicated Servers
All needed DKIM records will be created automatically by our cloud platform when you add a domain as hosted in a semi-dedicated server account, so if you decide to purchase a semi-dedicated server package, you won’t need to set up anything to be able to take advantage of the email validation system. The domain should use our name servers in order for its DNS records to be managed by our company and provided that this requirement is matched, a private encryption key will be generated on our mail servers and a public key will be sent to the DNS system by a special TXT resource record. All addresses that you create using the domain name will be protected by DomainKeys Identified Mail, which will make it impossible for third parties to fake any email address. Both you and your colleagues or customers can take advantage of this functionality, as it will guarantee a higher level of security for your email communication.
