DomainKeys Identified Mail, or DKIM, is a method for confirming the genuineness of an email message using an e-signature. When DKIM is activated for a particular domain name, a public cryptographic key is published to the global DNS system and a private one is kept on the mail server. When a new message is sent, a signature is issued using the private key and when the email message is delivered, that signature is checked by the POP3/IMAP email server using the public key. Thus, the recipient can easily know if the email message is legitimate or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email message has been changed in the meantime as well, so DKIM can also be used to ensure that the sent and the received email messages are identical and that nothing has been added or erased. This authentication system will increase your email security, as you can verify the legitimacy of the important emails that you receive and your colleagues can do likewise with the emails that you send them. Depending on the given email service provider’s policy, an email that fails to pass the check may be deleted or may appear in the recipient’s mailbox with a warning sign.

DomainKeys Identified Mail in Shared Web Hosting

If you host a domain in a shared web hosting account with us, all the necessary records for using the DomainKeys Identified Mail option will be set up by default. This will happen as soon as you add the domain name in the Hosted Domains section of the Hepsia Control Panel, on the condition that your domain also uses our NS resource records. A private cryptographic key will be generated on our email servers, while a public key will be sent to the Domain Name System automatically by using the TXT resource record. Thus, you won’t need to do anything manually and you’ll be able to enjoy all the benefits of this email validation system – your emails will be delivered to any destination without being discarded and nobody will be able to send out email messages forging your email addresses. The latter is quite important in case the nature of your web presence involves sending out regular newsletters or offers via email to potential and current clients.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated hosting plans come with DomainKeys Identified Mail enabled by default, so in case you pick a semi-dedicated hosting plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the email authentication system will be created automatically – a private key on our email servers for the e-signature and a TXT record carrying the public key for the global DNS database. Since the protection is set up for a given domain, all e-mail addresses created under it will carry a signature, so you won’t need to worry that the emails that you send may not be delivered to their target address or that somebody may forge any of your addresses and attempt to spam/scam people. This may be very important if you rely on e-communication in your business, since your associates and/or clients will be able to distinguish real email messages from counterfeit ones.
