DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email using an e-signature. When DomainKeys Identified Mail is enabled for a particular domain name, a public encryption key is published to the global DNS database and a private one is kept on the email server. When a new email message is sent, a signature is issued using the private key and when the message is received, the signature is verified by the incoming POP3/IMAP mail server using the public key. In this way, the receiver can easily know if the email message is genuine or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email has been altered in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received emails are identical and that nothing has been added or deleted. This email validation system will boost your email safety, as you can verify the authenticity of the important email messages that you get and your colleagues can do likewise with the email messages that you send them. Based on the particular email service provider’s adopted policies, an email that fails to pass the examination may be removed or may be delivered to the receiver’s mailbox with a warning notification.

DomainKeys Identified Mail in Hosting

If you purchase one of the Linux hosting that we’re offering, the DomainKeys Identified Mail option will be activated by default for any domain name that you add to your shared website hosting account, so you will not need to set up any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our MX and NS resource records (so that the email messages associated with this domain name will be handled by our cloud web hosting platform), a private key will be issued immediately on our mail servers and a TXT record with a public key will be sent to the DNS database. All email addresses created with this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target destination and the receivers will know that they are authentic, as the DomainKeys Identified Mail functionality makes it impossible for unsolicited parties to spoof your e-mail addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated hosting plans come with DKIM activated by default, so if you opt for a semi-dedicated server plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the validation system will be set up automatically – a private key on our mail servers for the electronic signature and a TXT record carrying the public key for the global Domain Name System. Since the DKIM protection is set up for a certain domain name, all e-mail addresses created under it will carry a signature, so you won’t need to worry that the email messages that you send out may not be delivered to their destination email address or that somebody may forge any of your email addresses and attempt to scam/spam people. This may be quite important when you use electronic communication in your business, since your colleagues and/or customers will be able to distinguish authentic messages from fake ones.
