DomainKeys Identified Mail (DKIM) is a validation system used to certify that an e-mail has been sent by an authorized email server or person. An e-signature is added to the header of the email message using a private encryption key. When the email is received, a public key that is available in the global DNS database is used to verify who exactly sent it and if its content has been altered in some way. The chief job of DKIM is to block the widespread scam and spam messages, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for example, but the signature does not correspond, you will either not get the message at all, or you will receive it with a warning note that most likely it’s not a legitimate one. It depends on email providers what exactly will happen with an email message which fails to pass the signature check. DKIM will also provide you with an extra layer of security when you communicate with your business associates, for example, as they can see for themselves that all the messages that you send are genuine and have not been tampered with on their way.
DomainKeys Identified Mail in Cloud Hosting
In case you host a domain in a cloud hosting account from us, all the obligatory records for using the DomainKeys Identified Mail option will be created by default. This will happen as soon as you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, provided that it also uses our NS resource records. A private key will be generated on our mail servers, whereas a public key will be sent to the global Domain Name System automatically using the TXT resource record. Thus, you won’t need to do anything manually and you will be able to take advantage of all the benefits of this email validation system – your messages will be delivered to any target audience without being rejected and nobody will be able to send messages forging your email addresses. The latter is truly important if the type of your web presence suggests sending periodic offers or newsletters via email to prospective and existing clients.
