DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an email message has been sent by an authenticated email server or individual. An electronic signature is added to the header of the message using a private cryptographic key. When the message is received, a public key that’s available in the global Domain Name System is used to confirm who actually sent it and whether its content has been modified in any way. The chief task of DKIM is to impede the widespread spam and scam 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, for instance, but the signature doesn’t match, you will either not receive the email at all, or you will receive it with an alert that most likely it’s not genuine. It depends on email service providers what exactly will happen with an email which fails to pass the signature check. DomainKeys Identified Mail will also supply you with an added protection layer when you communicate with your business associates, for example, since they can see for themselves that all the messages that you send are authentic and haven’t been modified on their way.

DomainKeys Identified Mail in Web Hosting

When you purchase one of the Linux web hosting that we are offering, the DomainKeys Identified Mail functionality will be enabled as standard for any domain name that you register under your shared website hosting account, so you will not have to create any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain name will be handled by our cloud web hosting platform), a private key will be issued right away on our email servers and a TXT record with a public key will be sent to the DNS database. All addresses set up with this domain will be protected by DKIM, so if you send out email messages such as periodic newsletters, they will reach their target audience and the recipients will know that the messages are genuine, as the DomainKeys Identified Mail option makes it impossible for unauthorized parties to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so in case you choose a semi-dedicated server package and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the authentication system will be created automatically – a private key on our mail servers for the electronic signature and a TXT record carrying the public key for the DNS database. Since the protection is set up for a given domain, all addresses created under it will have a signature, so you will not have to worry that the messages that you send out may not be delivered to their target address or that someone may forge any of your addresses and attempt to spam/scam people. This may be extremely important if you rely on e-communication in your business, since your associates and/or clients will be able to distinguish genuine emails from fake ones.
