DomainKeys Identified Mail, or DKIM, is a system for confirming the genuineness of an email message using an electronic signature. When DKIM is activated for a particular domain, a public cryptographic key is published to the global Domain Name System and a private one is stored on the email server. When a new email message is sent, a signature is issued using the private key and when the email is delivered, the signature is validated by the incoming POP3/IMAP email server using the public key. In this way, the receiver can easily tell if the email is authentic or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email has been edited on its way as well, so DKIM can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been added or deleted. This authentication system will boost your email security, since you can confirm the legitimacy of the important emails that you get and your associates can do the same with the messages that you send them. Depending on the given email service provider’s policy, a message that fails to pass the check may be deleted or may reach the receiver’s mailbox with a warning flag.

DomainKeys Identified Mail in Website Hosting

In case you host a domain in a website hosting account from us, all the compulsory records for using the DomainKeys Identified Mail option will be added by default. This will happen the moment you add the domain name in , as long as your domain also uses our NS records. A private encryption key will be created on our mail servers, whereas a public key will be published to the global DNS database automatically by using the TXT resource record. In this way, you won’t have to do anything manually and you will be able to take advantage of all the benefits of this authentication system – your messages will be delivered to any destination without being denied and no one will be able to send messages forging your addresses. The latter is rather important in case the type of your Internet presence involves sending out periodic offers or newsletters via email to prospective and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail activated by default, so in case you choose a semi-dedicated package and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private key on our email servers for the digital signature and a TXT record carrying the public key for the DNS system. Since the protection is set up for a particular domain, all e-mail addresses created with it will carry a signature, so you will not need to worry that the messages that you send may not be delivered to their destination email address or that someone may forge any of your email addresses and try to scam/spam people. This may be quite essential if you use email communication in your business, as your associates and/or customers will be able to distinguish authentic messages from forged ones.
