DomainKeys Identified Mail, or DKIM, is a method for confirming the authenticity of an email by using an electronic signature. When DomainKeys Identified Mail is enabled for a certain domain name, a public encryption key is published to the global DNS system and a private one is kept on the mail server. If a new email message is sent, a signature is issued using the private key and when the email is delivered, that signature is ‘scanned’ by the receiving server using the public key. Thus, the receiver can easily distinguish if the message is legitimate or if the sender’s email address has been forged. A mismatch will appear if the content of the email has been edited in the meantime 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 increase your email security, since you can confirm 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 adopted policy, an email message that fails to pass the test may be erased or may show up in the receiver’s inbox with a warning flag.

DomainKeys Identified Mail in Cloud Hosting

If you host a domain name in a cloud hosting account from us, all the required records for using the DomainKeys Identified Mail option will be added by default. This will happen the moment you add the domain in the Control Panel’s Hosted Domains section, on the condition that the domain also uses our NS resource records. A private encryption key will be generated on our mail servers, whereas a public key will be published to the Domain Name System automatically by using the TXT record. Thus, you won’t need to do anything manually and you’ll be able to take full advantage of all the benefits of this validation system – your email messages will reach any target audience without being disallowed and no one will be able to send out email messages faking your e-mail addresses. The latter is really important if the essence of your Internet presence involves sending out periodic offers or newsletters via email to potential and existing customers.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DKIM enabled by default, so if you select a semi-dedicated plan and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the validation system will be created automatically – a private cryptographic key on our email servers for the digital signature and a TXT record carrying the public key for the global Domain Name System. As the protection is set up for a particular domain, all addresses created using it will carry a signature, so you won’t have to worry that the emails that you send may not be delivered to their destination address or that somebody may forge any of your addresses and attempt to scam/spam people. This may be very important if you use e-communication in your business, as your colleagues and/or clients will be able to distinguish authentic emails from bogus ones.
