DomainKeys Identified Mail (DKIM) is a validation system used to check that an e-mail message has been sent by an authenticated mail server or individual. An electronic signature is attached to the message’s header using a private encryption key. When the email is received, a public key that is available in the global DNS database is used to confirm who actually sent it and if its content has been modified in any way. The fundamental purpose of DomainKeys Identified Mail is to stop the widespread scam and spam emails, as it makes it impossible to forge an email address. If a message is sent from an email address claiming to belong to your bank, for example, but the signature does not match, you will either not get the email message at all, or you’ll get it with a warning alert that most probably it is not an authentic one. It depends on mail service providers what exactly will happen with an email which fails to pass the signature check. DKIM will also give you an additional security layer when you communicate with your business partners, for instance, as they can see that all the emails that you send are genuine and haven’t been tampered with in the meantime.

DomainKeys Identified Mail in Shared Web Hosting

In case you host a domain in a shared web hosting account with us, all the needed records for using the DomainKeys Identified Mail option will be added by default. This will happen the moment you add the domain name in the Control Panel’s Hosted Domains section, as long as your domain also uses our NS records. A private cryptographic key will be generated on our mail servers, whereas a public key will be sent to the global DNS database automatically using the TXT record. Thus, you won’t need to do anything manually and you’ll be able to take advantage of all the benefits of this authentication system – your email messages will be delivered to any audience without being disallowed and nobody will be able to send email messages forging your addresses. The latter is pretty important in case the type of your web presence suggests sending regular newsletters or offers via email to potential and existing clients.

DomainKeys Identified Mail in Semi-dedicated Hosting

The DomainKeys Identified Mail protection service is offered by default with any domain that’s registered through a semi-dedicated server account with us. The domain should also use our name servers, so that its DNS resource records are handled by our platform. The latter makes it possible for a special TXT resource record to be created, which is in fact the public cryptographic key that confirms if a particular email message is genuine or not. Such a record is created when a new domain name is added to an account through the Hepsia Control Panel and at the same time, a private key is created on our mail servers. If you use our email and web hosting services, your emails will always reach their target destination and you won’t need to worry about unauthorized people using your email addresses for scamming or spamming purposes, which is essential when you use emails to get in touch with your business associates.
