DomainKeys Identified Mail (DKIM) is an email authentication system used to certify that an email has been sent by an authenticated mail server or individual. An e-signature is added to the email message’s header using a private cryptographic key. When the email is received, a public key that is available in the global DNS database is used to verify who actually sent it and if its content has been edited in some way. The essential task of DKIM is to hinder the widely spread spam and scam emails, as it makes it impossible to forge an email address. If an email message is sent from an address claiming to belong to your bank, for example, but the signature does not correspond, you will either not receive the email at all, or you will get it with a warning alert that most likely it is not a legitimate one. It depends on email service providers what exactly will happen with an email message that fails to pass the signature check. DKIM will also give you an added layer of security when you communicate with your business partners, for instance, since they can see for themselves that all the e-mails that you exchange are legitimate and have not been meddled with on their way.
DomainKeys Identified Mail in Shared Hosting
When you purchase any of the shared plans that we’re offering, the DomainKeys Identified Mail option will be activated as standard for any domain that you register under your account, so you won’t have to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX resource records (so that the emails associated with this domain will be handled by our cloud hosting platform), a private cryptographic key will be issued immediately on our email servers and a TXT resource record with a public key will be sent to the Domain Name System. All email addresses created with this domain will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target audience and the recipients will know that the messages are authentic, because the DomainKeys Identified Mail functionality makes it impossible for unauthorized individuals to spoof your e-mail addresses.
