DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an email message has been sent by an authenticated email server or individual. An electronic signature is attached to the header of the email message by using a private cryptographic key. When the email is received, a public key that is available in the global Domain Name System is used to check who actually sent it and if the content has been changed in any way. The fundamental job of DKIM is to avert the widely spread scam and spam 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 example, but the signature doesn’t correspond, you will either not receive the email message at all, or you’ll get it with a warning note that most probably it is not a legitimate one. It depends on email service providers what exactly will happen with an email which fails to pass the signature test. DomainKeys Identified Mail will also offer you an extra protection layer when you communicate with your business associates, for instance, since they can see for themselves that all the emails that you exchange are legitimate and haven’t been modified on their way.

DomainKeys Identified Mail in Shared Web Hosting

In case you host a domain name in a shared web hosting account from our company, all the compulsory records for using the DomainKeys Identified Mail feature will be created by default. This will happen the moment you add the domain name in the Control Panel’s Hosted Domains section, provided that the domain also uses our NS records. A private key will be generated on our email servers, whereas a public key will be added to the global Domain Name System automatically by using the TXT record. Thus, you won’t have to do anything manually and you’ll be able to enjoy all the benefits of this authentication system – your messages will reach any target audience without being disallowed and no one will be able to send email messages faking your e-mail addresses. The latter is really important in case the nature of your worldwide web presence suggests sending out periodic newsletters or offers via email to prospective and existing clients.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so if you select a semi-dedicated package and you add a domain using our name servers via your Hepsia Control Panel, the records required for the email validation system will be set up automatically – a private cryptographic key on our email servers for the digital signature and a TXT record carrying the public key for the DNS database. As the DKIM protection is set up for a given domain name, all addresses created using it will carry a signature, so you won’t have to worry that the emails that you send may not be delivered to their target email address or that somebody may fake any of your email addresses and try to spam/scam people. This may be rather important if you rely on email communication in your business, as your colleagues and/or clients will be able to distinguish real messages from fake ones.
