DomainKeys Identified Mail (DKIM) is a validation system used to confirm that an e-mail has been sent by an authorized email server or person. An e-signature is attached to the header of the email using a private encryption key. When the email message is received, a public key that is available in the global DNS database is used to check who actually sent it and if its content has been changed in any way. The prime task of DKIM is to hinder the widely spread spam and scam email messages, as it makes it impossible to fake an email address. If an email is sent from an address claiming to belong to your bank, for example, but the signature doesn’t match, you will either not receive the email at all, or you will get it with a warning notice that most probably it’s not genuine. It depends on email service providers what exactly will happen with an email which fails to pass the signature test. DomainKeys Identified Mail will also give you an additional security layer when you communicate with your business partners, for example, as they can see that all the e-mails that you send are legitimate and haven’t been meddled with on their way.
DomainKeys Identified Mail in Website Hosting
In case you host a domain in a website hosting account with us, all the mandatory records for using the DomainKeys Identified Mail option will be created by default. This will happen once you add the domain name in the Control Panel’s Hosted Domains section, provided that the domain also uses our NS records. A private cryptographic key will be generated on our email servers, whereas a public key will be published to the global Domain Name System automatically by using the TXT record. In this way, you won’t have to do anything manually and you’ll be able to take full advantage of all the benefits of this email validation system – your emails will be delivered to any target audience without being disallowed and nobody will be able to send email messages faking your e-mail addresses. The latter is quite important if the essence of your worldwide web presence involves sending periodic offers or newsletters via email to prospective and existing customers.
