DomainKeys Identified Mail (DKIM) is an email validation system used to check that an e-mail has been sent by an authorized server or individual. A digital signature is attached to the email’s header using a private encryption key. When the email is received, a public key that is available in the global DNS database is used to verify who exactly sent it and if the content has been edited in some way. The primary function of DomainKeys Identified Mail is to avert the widely spread scam and spam messages, 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 or financial institution, for example, but the signature does not match, you will either not receive the message at all, or you’ll receive it with a warning notification that most probably it is not a legitimate one. It depends on email providers what exactly will happen with an email message which fails the signature examination. DomainKeys Identified Mail will also give you an added layer of safety when you communicate with your business partners, for example, since they can see that all the email messages that you send are legitimate and haven’t been modified in the meantime.

DomainKeys Identified Mail in Website Hosting

If you host a domain in a website hosting account with us, all the necessary records for using the DomainKeys Identified Mail feature will be set up by default. This will happen the moment you add the domain name in the Control Panel’s Hosted Domains section, as long as the domain also uses our NS resource records. A private cryptographic key will be created on our mail servers, whereas a public key will be published to the DNS database automatically using the TXT resource record. Thus, you won’t need to do anything manually and you will be able to make use of all the benefits of this validation system – your messages will be sent to any target destination without being rejected and no one will be able to send emails forging your addresses. The latter is truly important in case the type of your online presence involves sending regular offers or newsletters via email to prospective and existing customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated packages come with DomainKeys Identified Mail enabled by default, so in case you select a semi-dedicated hosting plan and you add a domain using our name servers through your Hepsia Control Panel, the records required for the email authentication system will be set up automatically – a private cryptographic key on our mail servers for the e-signature and a TXT resource record carrying the public key for the global Domain Name System. Since the protection is set up for a specific domain, all email addresses created with it will have 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 try to spam/scam people. This may be quite important if you rely on e-communication in your business, as your associates and/or customers will be able to distinguish authentic messages from fake ones.
