DomainKeys Identified Mail (DKIM) is an authentication system used to check that an e-mail message has been sent by an authenticated person or mail server. An electronic signature is added to the message’s header by using a private encryption key. When the email is received, a public key that’s available in the global Domain Name System is used to validate who actually sent it and whether its content has been edited in some way. The primary task of DomainKeys Identified Mail is to prevent the widely spread spam and scam messages, as it makes it impossible to forge an email address. If an email is sent from an address claiming to belong to your bank, for example, but the signature does not correspond, you will either not receive the message at all, or you’ll get it with a warning that most probably it’s not a genuine one. It depends on email service providers what exactly will happen with an email that fails to pass the signature check. DKIM will also offer you an extra layer of security when you communicate with your business partners, for example, as they can see for themselves that all the messages that you exchange are authentic and have not been manipulated on their way.

DomainKeys Identified Mail in Shared Hosting

When you get one of the shared hosting plans that we are offering, the DomainKeys Identified Mail option will be enabled by default for any domain name that you register under your website hosting account, so you won’t have to set up any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX resource records (so that the emails associated with this domain name will be handled by our cloud web hosting platform), a private cryptographic key will be generated immediately on our mail servers and a TXT record with a public key will be sent to the global Domain Name System. All addresses set up with this domain name will be protected by DomainKeys Identified Mail, so if you send emails such as regular newsletters, they will reach their target destination and the receivers will know that the messages are authentic, since the DKIM feature makes it impossible for unauthorized individuals to forge your email addresses.
