DomainKeys Identified Mail, or DKIM, is a system for validating the authenticity of an email message by using an e-signature. When DomainKeys Identified Mail is activated for a certain domain name, a public key is published to the global DNS database and a private one is kept on the mail server. When a new email 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 recognize 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 has been changed in the meantime as well, so DKIM can also be used to make sure that the sent and the received messages are identical and that nothing has been added or erased. This validation system will increase your email safety, as you can confirm the authenticity of the important email messages that you receive and your associates can do the exact same thing with the emails that you send them. Depending on the given email service provider’s adopted policy, an email message that fails to pass the examination may be erased or may show up in the recipient’s inbox with a warning.

DomainKeys Identified Mail in Cloud Hosting

If you host a domain in a cloud hosting account with our company, all the obligatory records for using the DomainKeys Identified Mail feature will be set up by default. This will happen once you add the domain in the Control Panel’s Hosted Domains section, on the condition that your domain also uses our NS records. A private cryptographic key will be created on our mail servers, whereas a public key will be published to the Domain Name System automatically using the TXT resource record. Thus, you won’t need to do anything manually and you’ll be able to make use of all the benefits of this email validation system – your emails will reach any target audience without being rejected and no one will be able to send out emails forging your email addresses. The latter is truly important if the type of your online presence suggests sending out regular offers or newsletters via email to prospective and existing clients.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting packages come with DKIM enabled by default, so in case you opt for a semi-dedicated plan and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the authentication system will be created automatically – a private encryption key on our email servers for the electronic signature and a TXT resource record carrying the public key for the global DNS system. Since the protection is set up for a particular domain, all addresses created using it will have a signature, so you won’t have to worry that the messages that you send out may not be delivered to their destination email address or that somebody may fake any of your email addresses and try to spam/scam people. This may be rather important when you rely on e-communication in your business, as your associates and/or customers will be able to distinguish real emails from forged ones.
