DomainKeys Identified Mail, or DKIM, is a system for validating the authenticity of an email using a digital signature. When DKIM is enabled for a certain domain, 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 generated using the private key and when the email message is received, the signature is authenticated by the incoming POP3/IMAP mail server using the public key. Thus, the recipient can easily tell if the email message is authentic or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email message has been edited on its way as well, so DKIM can also be used to make sure that the sent and the received email messages are identical and that nothing has been attached or erased. This email validation system will strengthen your email security, as you can verify the authenticity of the important email messages that you get and your associates can do likewise with the messages that you send them. Depending on the given email provider’s policies, an email message that fails the examination may be deleted or may enter the receiver’s inbox with a warning flag.

DomainKeys Identified Mail in Shared Hosting

When you obtain any of the Linux shared hosting that we offer, the DomainKeys Identified Mail option will be enabled as standard for any domain that you add to your shared website hosting account, so you will not need to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our NS and MX resource records (so that the email messages associated with this domain will be handled by our cloud platform), a private encryption key will be generated right away on our mail servers and a TXT record with a public key will be sent to the global Domain Name System. All email addresses created using this domain will be protected by DKIM, so if you send out email messages such as regular newsletters, they will reach their target destination and the recipients will be sure that they are legitimate, since the DomainKeys Identified Mail functionality makes it impossible for unauthorized individuals to forge your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DKIM enabled by default, so in case you pick a semi-dedicated package and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the email 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 DNS system. As the DKIM protection is set up for a specific domain, all e-mail addresses created under it will have a signature, so you will not need to worry that the messages that you send out may not reach their target email address or that someone may spoof any of your addresses and attempt to spam/scam people. This may be extremely important if you rely on email communication in your business, since your associates and/or customers will be able to distinguish authentic emails from counterfeit ones.
