DomainKeys Identified Mail (DKIM) is an email authentication system used to prove that an email message has been sent by an authenticated person or mail server. A digital signature is added to the header of the message using a private encryption key. When the message is received, a public key that is available in the global Domain Name System is used to check who exactly sent it and if the content has been changed in any way. The essential function of DomainKeys Identified Mail is to block the widespread scam and spam emails, as it makes it impossible to forge an email address. If an email message is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t match, you will either not receive the email message at all, or you’ll get it with a warning notification that most probably it is not legitimate. It depends on email providers what exactly will happen with an email that fails the signature examination. DomainKeys Identified Mail will also give you an additional protection layer when you communicate with your business associates, for instance, since they can see for themselves that all the messages that you exchange are legitimate and have not been tampered with on their way.

DomainKeys Identified Mail in Shared Web Hosting

If you host a domain in a shared web hosting account with our company, all the compulsory records for using the DomainKeys Identified Mail option will be set up by default. This will happen the moment you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, provided that 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 Domain Name System automatically by using the TXT record. Thus, you won’t need 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 audience without being denied and no one will be able to send messages faking your addresses. The latter is truly important in case the nature of your online presence involves sending periodic newsletters or offers via email to prospective and existing clients.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DKIM enabled by default, so in case you opt for a semi-dedicated hosting plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the validation system will be created automatically – a private cryptographic key on our mail servers for the electronic signature and a TXT record carrying the public key for the DNS database. Since the DKIM protection is set up for a specific domain, all email addresses created with it will carry a signature, so you won’t have to worry that the email messages that you send may not be delivered to their destination address or that somebody may spoof any of your addresses and try to scam/spam people. This may be extremely important if you rely on email communication in your business, since your colleagues and/or clients will be able to distinguish authentic messages from false ones.
