DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an e-mail message has been sent by an authenticated mail server or individual. A digital signature is added to the header of the message using a private cryptographic key. When the email is received, a public key that is available in the global Domain Name System is used to verify who actually sent it and if its content has been modified in any way. The chief function of DKIM is to avert the widely spread scam and spam 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, for instance, but the signature doesn’t correspond, you will either not receive the message at all, or you’ll receive it with a warning that most likely it’s not an authentic one. It depends on mail service providers what exactly will happen with an email which fails the signature check. DomainKeys Identified Mail will also offer you an added protection layer when you communicate with your business associates, for example, since they can see for themselves that all the messages that you send are legitimate and have not been modified in the meantime.
DomainKeys Identified Mail in Website Hosting
The DomainKeys Identified Mail option is pre-activated for all domains that are hosted in a website hosting account on our cloud website hosting platform, so you won’t need to do anything on your end to turn it on. The sole requirement is that the particular domain name should be hosted in a hosting account on our platform using our MX and NS resource records, so that the e-mail messages will go through our email servers. The private cryptographic key will be created on the server and the TXT resource record, which includes the public key, will be published to the global DNS system automatically, so you will not have to do anything manually on your end in order to enable this option. The DKIM email authentication system will enable you to send trustworthy emails, so if you are sending a newsletter or offers to clients, for instance, your emails will always reach their target destination, while unsolicited third parties won’t be able to spoof your email addresses.
