DomainKeys Identified Mail, or DKIM, is a method for checking the authenticity of an email message by using an e-signature. When DomainKeys Identified Mail is activated for a specific domain, a public cryptographic key is published to the global Domain Name System and a private one is kept on the email server. If a new email message is sent, a signature is generated using the private key and when the message is delivered, that signature is verified by the incoming POP3/IMAP mail server using the public key. In this way, the receiver can easily tell if the email is authentic or if the sender’s address has been forged. A mismatch will occur if the content of the email message has been changed on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered messages are identical and that nothing has been added or deleted. This email validation system will strengthen your email safety, since you can validate the genuineness of the important emails that you receive and your colleagues can do the same with the messages that you send them. Depending on the given mail service provider’s policies, a message that fails to pass the check may be deleted or may emerge in the receiver’s inbox with a warning symbol.

DomainKeys Identified Mail in Web Hosting

In case you host a domain in a web hosting account from our company, all the necessary records for using the DomainKeys Identified Mail option will be added by default. This will happen as soon as you add the domain name in the Control Panel’s Hosted Domains section, provided that the domain also uses our NS records. A private key will be generated on our email servers, whereas a public key will be published to the Domain Name System automatically by using the TXT record. In this way, you won’t have to do anything manually and you’ll be able to take full advantage of all the benefits of this email validation system – your messages will reach any audience without being disallowed and nobody will be able to send messages faking your e-mail addresses. The latter is quite important in case the nature of your worldwide web presence involves sending periodic newsletters or offers via email to potential and current customers.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DKIM activated by default, so if you opt for a semi-dedicated server package and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the authentication system will be created automatically – a private encryption key on our mail 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 specific domain, all email addresses created using it will have a signature, so you will not need to worry that the emails that you send may not be delivered to their destination address or that someone may spoof any of your addresses and attempt to scam/spam people. This may be rather essential if you use e-communication in your business, as your colleagues and/or customers will be able to distinguish authentic messages from spoofed ones.
