DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email message using an e-signature. When DomainKeys Identified Mail is enabled for a certain domain name, a public key is published to the global DNS database and a private one is kept on the email server. When a new message is sent, a signature is generated using the private key and when the email message is received, that signature is validated by the incoming email server using the public key. Thus, the receiver can easily discern if the email message is authentic or if the sender’s email address has been forged. A discrepancy will appear if the content of the email message has been edited on its way as well, so DKIM can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or removed. This email validation system will boost your email safety, as you can validate the genuineness 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 email provider’s policy, an email message that fails to pass the test may be deleted or may reach the recipient’s mailbox with a warning notification.

DomainKeys Identified Mail in Cloud Web Hosting

In case you host a domain name in a cloud web hosting account with us, all the necessary records for using the DomainKeys Identified Mail feature will be added by default. This will happen as soon as you add the domain in the Hosted Domains section of the Hepsia Control Panel, as long as the domain also uses our NS records. A private cryptographic key will be generated on our mail servers, while a public key will be added to the DNS database automatically by using the TXT record. In this way, you won’t have to do anything manually and you will be able to make use of all the benefits of this validation system – your messages will reach any target audience without being rejected and nobody will be able to send messages faking your e-mail addresses. The latter is truly important if the essence of your worldwide web presence involves sending out periodic offers or newsletters via email to prospective and current customers.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated plans come with DomainKeys Identified Mail activated by default, so if you select a semi-dedicated server package and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the authentication system will be created automatically – a private cryptographic key on our email servers for the e-signature and a TXT resource record carrying the public key for the global DNS system. As the protection is set up for a particular domain name, all email addresses created under it will have a signature, so you won’t need to worry that the emails that you send out may not be delivered to their target address or that somebody may fake any of your email addresses and attempt to spam/scam people. This may be really important if you rely on email communication in your business, as your partners and/or customers will be able to distinguish genuine messages from bogus ones.
