DomainKeys Identified Mail, or DKIM, is a system for validating the authenticity of an email message using an electronic signature. When DomainKeys Identified Mail is activated for a specific domain name, a public key is published to the global DNS database and a private one is kept on the mail server. When a new email message is sent, a signature is issued using the private key and when the email message is received, the signature is checked by the incoming POP3/IMAP mail server using the public key. In this way, the receiver can easily know if the email message is legitimate or if the sender’s address has been spoofed. A mismatch will appear if the content of the email message has been modified on its way as well, so DKIM can also be used to ensure that the sent and the received emails are identical and that nothing has been attached or erased. This email authentication system will strengthen your email security, as you can verify the legitimacy of the important emails that you get and your associates can do the exact same thing with the email messages that you send them. Depending on the particular email provider’s policies, a message that fails to pass the test may be removed or may appear in the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Shared Website Hosting

In case you host a domain name in a shared website hosting account with us, all the required records for using the DomainKeys Identified Mail feature will be created by default. This will happen once you add the domain name in , on the condition that it also uses our NS records. A private cryptographic key will be created on our email servers, while a public key will be added to the DNS system automatically by using the TXT resource record. Thus, you will not need to do anything manually and you will be able to enjoy all the benefits of this authentication system – your email messages will reach any target destination without being discarded and no one will be able to send emails forging your email addresses. The latter is rather important if the type of your web presence involves sending regular newsletters or offers via email to prospective and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting packages come with DomainKeys Identified Mail activated by default, so in case you choose a semi-dedicated server package 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 mail servers for the electronic signature and a TXT record carrying the public key for the global DNS database. As the protection is set up for a particular domain name, all email addresses created with it will carry a signature, so you won’t have to worry that the emails that you send out may not reach their destination email address or that somebody may spoof any of your addresses and attempt to scam/spam people. This may be very essential in case you rely on email communication in your business, as your partners and/or customers will be able to distinguish authentic emails from false ones.
