DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email message by using an electronic signature. When DomainKeys Identified Mail is activated for a given domain name, a public cryptographic key is published to the global DNS database and a private one is kept on the mail server. When a new email is sent, a signature is issued using the private key and when the email is received, the signature is verified by the incoming POP3/IMAP mail server using the public key. In this way, the recipient can easily discern if the message is genuine or if the sender’s email address has been spoofed. A discrepancy will appear if the content of the email has been changed on its way as well, so DKIM can also be used to make sure that the sent and the delivered emails are identical and that nothing has been added or erased. This email validation system will heighten your email safety, as you can validate the authenticity of the important emails that you receive and your partners can do likewise with the emails that you send them. Based on the given mail service provider’s adopted policy, an email that fails to pass the examination may be erased or may be delivered to the recipient’s inbox with a warning symbol.

DomainKeys Identified Mail in Web Hosting

If you host a domain in a web hosting account from us, all the obligatory records for using the DomainKeys Identified Mail feature will be set up by default. This will happen as soon as you add the domain in the Control Panel’s Hosted Domains section, on the condition that your domain also uses our NS resource records. A private encryption key will be generated on our mail servers, while a public key will be published to the global DNS system automatically by using the TXT resource record. Thus, you will not have to do anything manually and you will be able to make use of all the benefits of this email validation system – your messages will be delivered to any target destination without being disallowed and nobody will be able to send messages faking your e-mail addresses. The latter is quite important if the nature of your web presence suggests sending regular offers or newsletters via email to potential and current clients.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting packages come with DomainKeys Identified Mail enabled by default, so in case you select a semi-dedicated plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the email authentication system will be created automatically – a private encryption key on our mail servers for the electronic signature and a TXT record carrying the public key for the Domain Name System. Since the DKIM protection is set up for a certain domain, all e-mail addresses created under it will have a signature, so you will not need to worry that the emails that you send may not reach their destination email address or that someone may forge any of your email addresses and attempt to scam/spam people. This may be extremely essential in case you rely on email communication in your business, as your colleagues and/or clients will be able to distinguish legitimate messages from bogus ones.
