DomainKeys Identified Mail (DKIM) is an email validation system used to check that an e-mail has been sent by an authorized person or server. An electronic signature is attached to the header of the message using a private cryptographic key. When the email message is received, a public key that is available in the global Domain Name System is used to validate who exactly sent it and if the content has been edited in some way. The principal task of DKIM is to block the widely spread spam and scam emails, as it makes it impossible to forge 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 does not match, you will either not receive the email 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 which fails the signature check. DKIM will also provide you with an added security layer when you communicate with your business partners, for instance, since they can see for themselves that all the e-mails that you send are authentic and have not been manipulated on their way.
DomainKeys Identified Mail in Shared Hosting
If you host a domain name in a shared hosting account from us, all the necessary records for using the DomainKeys Identified Mail feature will be set up by default. This will happen once you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, provided that the domain also uses our NS resource records. A private key will be created on our email servers, whereas a public key will be sent to the Domain Name System automatically using the TXT resource record. Thus, you won’t have to do anything manually and you will be able to enjoy all the benefits of this validation system – your messages will reach any target audience without being rejected and nobody will be able to send out emails forging your email addresses. The latter is truly important in case the essence of your web presence suggests sending out 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 activated by default, so in case you choose a semi-dedicated plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be created automatically – a private cryptographic key on our email servers for the e-signature and a TXT record carrying the public key for the DNS database. Since the DKIM protection is set up for a certain domain, all email addresses created under it will have a signature, so you won’t have to worry that the email messages that you send may not reach their destination email address or that somebody may spoof any of your addresses and attempt to scam/spam people. This may be very important if you rely on email communication in your business, as your partners and/or clients will be able to distinguish authentic email messages from counterfeit ones.
