DomainKeys Identified Mail (DKIM) is a validation system used to prove that an e-mail has been sent by an authenticated person or mail server. A digital 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 DNS database is used to validate who actually sent it and if its content has been altered in some way. The essential purpose of DKIM is to hinder the widely spread scam and spam email messages, as it makes it impossible to fake an email address. If an email is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t correspond, you will either not get the email message at all, or you’ll receive it with a warning notification that most likely it is not genuine. It depends on email service providers what exactly will happen with an email which fails to pass the signature test. DKIM will also provide you with an added protection layer when you communicate with your business allies, for example, since they can see that all the messages that you exchange are genuine and haven’t been meddled with on their way.

DomainKeys Identified Mail in Shared Hosting

In case you host a domain in a shared hosting account from our company, all the obligatory records for using the DomainKeys Identified Mail feature will be set up by default. This will happen as soon as you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, on the condition that your domain also uses our NS records. A private cryptographic key will be generated on our email servers, while a public key will be sent to the DNS system automatically using the TXT resource record. In this way, you will not need to do anything manually and you will be able to take full advantage of all the benefits of this authentication system – your email messages will be delivered to any target audience without being discarded and no one will be able to send out email messages faking your addresses. The latter is pretty important in case the type of your worldwide web presence involves sending regular newsletters or offers via email to prospective and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail enabled by default, so in case you select 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 set up automatically – a private key on our mail servers for the digital signature and a TXT resource record carrying the public key for the DNS system. Since the DKIM protection is set up for a given domain, all email addresses created with it will have a signature, so you will not have to worry that the messages that you send out may not reach their target address or that somebody may forge any of your email addresses and attempt to scam/spam people. This may be quite essential in case you use electronic communication in your business, as your colleagues and/or clients will be able to distinguish real emails from counterfeit ones.
