DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an email has been sent by an authorized email server or individual. An e-signature is added to the header of the email message using a private cryptographic key. When the email is received, a public key that’s available in the global DNS database is used to check who exactly sent it and whether its content has been modified in some way. The principal task of DomainKeys Identified Mail is to stop the widespread spam and scam email messages, as it makes it impossible to fake an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t match, you will either not receive the email message at all, or you will receive it with a warning alert that most likely it is not a genuine one. It depends on email service providers what exactly will happen with an email which fails the signature examination. DomainKeys Identified Mail will also give you an extra layer of protection when you communicate with your business allies, for example, since they can see for themselves that all the e-mail messages that you send are legitimate and have not been modified on their way.
DomainKeys Identified Mail in Hosting
In case you host a domain name in a hosting
account with us, all the compulsory records for using the DomainKeys Identified Mail option will be set up by default. This will happen once you add the domain in the Control Panel’s Hosted Domains section, on the condition that the domain also uses our NS records. A private cryptographic key will be created on our email servers, while a public key will be published to the global DNS database automatically using the TXT resource record. In this way, you will not have to do anything manually and you will be able to make use of all the benefits of this email authentication system – your emails will be sent to any target destination without being denied and no one will be able to send out email messages faking your e-mail addresses. The latter is rather important if the type of your Internet presence suggests sending periodic offers or newsletters via email to prospective and existing clients.
DomainKeys Identified Mail in Semi-dedicated Servers
The DomainKeys Identified Mail functionality is offered by default with any domain name that is added to a semi-dedicated server
account with us. The domain must also use our name servers, so that its DNS resource records are managed by our system. The latter makes it possible for a special TXT record to be set up, which is actually the public cryptographic key that confirms if a specific email message is legitimate or not. This record is created the moment a new domain is registered in a semi-dedicated server account via the Hepsia Control Panel and at the same time, a private key is created on our email servers. If you use our email and web hosting services, your email messages will always reach their target destination and you will not have to worry about unsolicited persons spoofing your email addresses for spamming or scamming purposes, which is something rather important when you use emails to reach your business partners.
