DomainKeys Identified Mail (DKIM) is an email validation system used to certify that an e-mail has been sent by an authorized email server or person. An e-signature is added to the header of the email using a private cryptographic key. When the email is received, a public key that’s available in the global Domain Name System is used to validate who exactly sent it and whether its content has been changed in any way. The primary job of DKIM is to hamper the widely spread spam and scam email messages, as it makes it impossible to forge an email address. If an email is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature does not match, you will either not receive the message at all, or you’ll get it with a warning alert that most probably it’s not genuine. It depends on mail service providers what exactly will happen with an email that fails to pass the signature examination. DKIM will also provide you with an extra protection layer when you communicate with your business allies, for instance, as they can see that all the e-mail messages that you exchange are authentic and haven’t been tampered with on their way.
DomainKeys Identified Mail in Shared Hosting
In case you host a domain in a shared hosting account with our company, all the needed records for using the DomainKeys Identified Mail feature will be created by default. This will happen as soon as you add the domain in the Hosted Domains section of the Hepsia Control Panel, as long as the domain also uses our NS resource records. A private key will be created on our mail servers, while a public key will be sent to the Domain Name System automatically by using the TXT record. In this way, you won’t need to do anything manually and you will be able to enjoy all the benefits of this validation system – your messages will reach any target destination without being rejected and nobody will be able to send out messages faking your e-mail addresses. The latter is very important if the nature of your online presence involves sending out regular offers or newsletters via email to prospective and current clients.
DomainKeys Identified Mail in Semi-dedicated Hosting
The DomainKeys Identified Mail option is offered by default with any domain that’s registered through a semi-dedicated server account with our company. It should also use our name servers, so that its DNS resource records are handled by our system. The latter makes it possible for a special TXT resource record to be set up, which is actually the public key that confirms if a specific email is authentic or not. This record is set up once a domain is added to a semi-dedicated hosting account via the Hepsia Control Panel and at the same time, a private key is created on our mail servers. If you use our email and web hosting services, your emails will always reach their target readers and you won’t need to worry about unsolicited people using your email addresses for spamming or scamming purposes, which is something really important in case you use email messages to contact your business allies.
