DomainKeys Identified Mail (DKIM) is an authentication system used to check that an email message has been sent by an authorized individual or server. An e-signature is attached to the header of the email message using a private cryptographic key. When the message is received, a public key that’s available in the global Domain Name System is used to confirm who exactly sent it and if its content has been altered in some way. The main job of DKIM is to block the widely spread spam and scam messages, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t correspond, you will either not get the message at all, or you will receive it with a warning note that most probably it is not a legitimate one. It depends on mail service providers what exactly will happen with an email which fails to pass the signature examination. DomainKeys Identified Mail will also give you an extra layer of security when you communicate with your business partners, for instance, since they can see for themselves that all the email messages that you send are legitimate and have not been tampered with in the meantime.
DomainKeys Identified Mail in Shared Website Hosting
In case you host a domain in a shared website hosting account with our company, all the required records for using the DomainKeys Identified Mail option will be created by default. This will happen once you add the domain in the Hosted Domains section of the Hepsia Control Panel, on the condition that your domain also uses our NS resource records. A private encryption key will be created on our email servers, while a public key will be published to the global DNS database automatically using the TXT resource record. Thus, you won’t need to do anything manually and you will be able to enjoy all the benefits of this email authentication system – your email messages will reach any target audience without being rejected and nobody will be able to send out email messages faking your e-mail addresses. The latter is really important in case the type of your web presence involves sending periodic newsletters or offers via email to prospective and current clients.
