DomainKeys Identified Mail (DKIM) is an email authentication system used to prove that an email has been sent by an authenticated individual or server. An electronic signature is added to the header of the email message by using a private encryption key. When the email is received, a public key that’s available in the global DNS database is used to confirm who actually sent it and if its content has been edited in some way. The principal task of DomainKeys Identified Mail is to block the widespread spam and scam emails, 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, for instance, but the signature doesn’t match, you will either not get the message at all, or you’ll get it with a warning notification that most likely it’s not legitimate. It depends on email service providers what exactly will happen with an email message which fails to pass the signature examination. DKIM will also supply you with an extra protection layer when you communicate with your business allies, for example, as they can see that all the emails that you exchange are genuine and haven’t been tampered with in the meantime.

DomainKeys Identified Mail in Cloud Hosting

If you host a domain name in a cloud hosting account with us, all the necessary records for using the DomainKeys Identified Mail feature will be created by default. This will happen as soon as 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 key will be created on our email servers, whereas a public key will be added to the global DNS database automatically using the TXT resource record. In this way, you will not have to do anything manually and you will be able to make use of all the benefits of this validation system – your messages will be delivered to any target audience without being discarded and no one will be able to send out emails faking your addresses. The latter is very important if the type of your web presence suggests sending regular newsletters or offers via email to potential and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting services come with DomainKeys Identified Mail enabled by default, so in case you opt for a semi-dedicated hosting package and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the authentication system will be created automatically – a private key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the global DNS database. Since the protection is set up for a given domain name, all e-mail addresses created with it will carry a signature, so you will not need to worry that the messages that you send out may not be delivered to their target email address or that someone may forge any of your email addresses and attempt to scam/spam people. This may be rather important if you use e-communication in your business, as your colleagues and/or clients will be able to distinguish real email messages from phony ones.
