DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an email message has been sent by an authenticated mail server or individual. An electronic signature is added to the header of the email using a private cryptographic key. When the email message is received, a public key that is available in the global DNS database is used to check who exactly sent it and whether its content has been modified in any way. The primary purpose of DomainKeys Identified Mail is to stop the widespread spam and scam messages, 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 example, but the signature doesn’t match, you will either not receive the email message at all, or you will receive it with a warning that most probably it’s not a genuine one. It depends on mail service providers what exactly will happen with an email message which fails the signature examination. DomainKeys Identified Mail will also provide you with an added layer of security when you communicate with your business partners, for instance, since they can see for themselves that all the messages that you send are legitimate and haven’t been tampered with on their way.

DomainKeys Identified Mail in Web Hosting

If you host a domain name in a web hosting account with our company, all the required records for using the DomainKeys Identified Mail feature will be created by default. This will happen once you add the domain name in the Hosted Domains section of the Hepsia hosting Control Panel, as long as your domain also uses our NS resource records. A private encryption key will be generated on our email servers, while a public key will be published to the global DNS system automatically by using the TXT resource record. Thus, you will not have to do anything manually and you’ll be able to take advantage of all the benefits of this email authentication system – your email messages will reach any destination without being rejected and nobody will be able to send out email messages forging your addresses. The latter is quite important if the nature of your web presence suggests sending out periodic newsletters or offers via email to potential and existing customers.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DomainKeys Identified Mail activated by default, so if you opt for a semi-dedicated server package and you add a domain using our name servers through your Hepsia Control Panel, the records required for the validation system will be created automatically – a private encryption key on our mail servers for the e-signature and a TXT resource record carrying the public key for the DNS system. Since the protection is set up for a certain domain name, all email addresses created under it will carry a signature, so you will not have to worry that the email messages that you send may not reach their target address or that somebody may fake any of your email addresses and attempt to scam/spam people. This may be extremely important in case you rely on email communication in your business, as your colleagues and/or clients will be able to distinguish authentic emails from counterfeit ones.
