DomainKeys Identified Mail, or DKIM, is a method for validating the genuineness of an email using a digital signature. When DomainKeys Identified Mail is activated for a certain domain name, a public encryption key is published to the global Domain Name System and a private one is stored on the email server. If a new email is sent, a signature is issued using the private key and when the email message is delivered, that signature is verified by the incoming server using the public key. Thus, the recipient can easily recognize if the email is legitimate or if the sender’s address has been spoofed. A mismatch will occur if the content of the email has been altered 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 erased. This email authentication system will strengthen your email security, since you can verify the authenticity of the important email messages that you receive and your associates can do the exact same thing with the messages that you send them. Based on the given email service provider’s policy, a message that fails to pass the check may be removed or may be delivered to the receiver’s inbox with a warning alert.

DomainKeys Identified Mail in Cloud Website Hosting

The DomainKeys Identified Mail functionality is activated by default for all domain names that are hosted in a cloud website hosting account on our cloud website hosting platform, so you won’t have to do anything on your end to enable it. The only requirement is that the given domain should be hosted in a web hosting account on our platform using our NS and MX resource records, so that the email messages will go through our email servers. The private cryptographic key will be generated on the server and the TXT record, which includes the public key, will be published to the global Domain Name System automatically, so you won’t need to do anything manually on your end in order to enable this option. The DKIM email authentication system will allow you to send out trustable e-mails, so if you are sending a newsletter or offers to clients, for example, your email messages will always reach their target audience, whereas unauthorized 3rd parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated plans come with DomainKeys Identified Mail enabled by default, so in case you choose this type of hosting 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 key on our email servers for the electronic signature and a TXT resource record carrying the public key for the DNS database. Since the DKIM protection is set up for a given domain name, all email addresses created under it will carry a signature, so you won’t need to worry that the email messages that you send out may not be delivered to their target email address or that somebody may fake any of your email addresses and attempt to scam/spam people. This may be extremely essential when you use e-communication in your business, as your colleagues and/or clients will be able to distinguish authentic emails from fake ones.
