DomainKeys Identified Mail, or DKIM, is a system for confirming the legitimacy of an email using a digital signature. When DKIM is enabled for a particular domain, 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 is sent, a signature is generated using the private key and when the email message is received, the signature is validated by the POP3/IMAP mail server using the public key. Thus, the receiver can easily recognize if the email message is authentic or if the sender’s address has been forged. A discrepancy will occur if the content of the email has been edited 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 attached or erased. This email validation system will heighten your email security, as you can validate the authenticity of the important email messages that you get and your colleagues can do likewise with the emails that you send them. Based on the given mail service provider’s adopted policy, an email that fails to pass the examination may be removed or may appear in the recipient’s mailbox with a warning.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a shared hosting account on our cloud platform, so you will not need to do anything yourself to activate it. The sole requirement is that the particular domain should be hosted in a website hosting account on our platform using our MX and NS resource records, so that the e-mails will go through our mail servers. The private key will be generated on the server and the TXT resource record, which includes the public key, will be published to the Domain Name System automatically, so you will not need to do anything manually on your end in order to activate this functionality. The DomainKeys Identified Mail validation system will enable you to send trustable email messages, so if you’re sending offers or a newsletter to customers, for example, your emails will always reach their target viewers, while unauthorized third parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

All mandatory DKIM records will be set up automatically by our cloud platform when you add a domain name as hosted in a semi-dedicated server account, so in case you decide to buy a semi-dedicated server plan, you will not have to set up anything to be able to take advantage of the email validation system. The domain name should use our name servers so that its DNS resource records can be managed on our end and as long as this condition is satisfied, a private encryption key will be created on our email servers and a public key will be sent to the global DNS database by a special TXT record. All addresses that you create with the domain name will be protected by DomainKeys Identified Mail, which will make it impossible for third parties to forge any email address. Both you and your associates or clients can benefit from this service, as it will guarantee a much higher level of security for your email correspondence.
