DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email message by using a digital signature. When DomainKeys Identified Mail is activated for a certain domain, a public cryptographic key is published to the global DNS database and a private one is kept on the email server. When a new email is sent, a signature is issued using the private key and when the email is delivered, the signature is authenticated by the POP3/IMAP email server using the public key. In this way, the receiver can easily discern if the email is authentic or if the sender’s address has been forged. A mismatch will appear if the content of the email has been modified in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received messages are identical and that nothing has been attached or removed. This email validation system will strengthen your email safety, since you can verify the authenticity of the important emails that you receive and your associates can do the exact same thing with the emails that you send them. Depending on the given mail service provider’s adopted policies, an email message that fails to pass the check may be erased or may appear in the recipient’s mailbox with a warning flag.

DomainKeys Identified Mail in Cloud Hosting

If you host a domain name in a cloud hosting account with our company, all the necessary records for using the DomainKeys Identified Mail functionality will be added by default. This will happen the moment you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, provided that the domain also uses our NS resource records. A private key will be created on our mail servers, while a public key will be sent to the global Domain Name System automatically using the TXT resource record. In this way, you will not have to do anything manually and you will be able to enjoy all the benefits of this authentication system – your email messages will be sent to any audience without being rejected and no one will be able to send email messages forging your email addresses. The latter is truly important if the type of your online presence involves sending out regular offers or newsletters via email to prospective and current clients.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail activated by default, so if you opt for a semi-dedicated hosting plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the email validation system will be set up automatically – a private encryption key on our email servers for the digital signature and a TXT record carrying the public key for the global DNS system. Since the DKIM protection is set up for a specific domain name, all addresses created under it will carry a signature, so you won’t have to worry that the messages that you send out may not reach their destination email address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be very essential in case you rely on email communication in your business, as your partners and/or clients will be able to distinguish legitimate messages from counterfeit ones.
