DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an email message has been sent by an authenticated email server or individual. An e-signature is attached to the header of the email by using a private key. When the message 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 modified in any way. The fundamental task of DomainKeys Identified Mail is to impede the widespread spam and scam emails, as it makes it impossible to fake an email address. If a message is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not receive the message at all, or you’ll receive it with an alert that most probably it is not an authentic one. It depends on email service providers what exactly will happen with an email that fails to pass the signature examination. DKIM will also offer you an additional security layer when you communicate with your business associates, for instance, as they can see that all the e-mails that you exchange are genuine and have not been modified in the meantime.
DomainKeys Identified Mail in Shared Hosting
You will be able to make use of DomainKeys Identified Mail with each and every shared hosting that we are offering without doing anything in particular, as the obligatory records for using this email authentication system are set up automatically by our hosting platform when you add a domain to an active hosting account using the Hepsia Control Panel. If the particular domain name uses our NS records, a private cryptographic key will be generated and kept on our mail servers and a TXT record with a public key will be sent to the global DNS system. In case you send out periodic messages to customers or business partners, they will always be delivered and no unauthorized person will be able to forge your email address and make it look like you have composed a particular email message.
