DomainKeys Identified Mail (DKIM) is an email authentication system used to prove that an e-mail has been sent by an authorized person or email server. An electronic signature is attached to the email’s header using a private encryption key. When the message is received, a public key that’s available in the global Domain Name System is used to verify who exactly sent it and whether its content has been changed in some way. The primary purpose of DKIM is to prevent the widely spread spam and scam messages, as it makes it impossible to forge an email address. If a message is sent from an email 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 that most likely it’s not a legitimate one. It depends on email service providers what exactly will happen with an email message that fails to pass the signature test. DKIM will also offer you an added layer of security when you communicate with your business associates, for example, as they can see for themselves that all the emails that you exchange are genuine and haven’t been tampered with on their way.
DomainKeys Identified Mail in Shared Website Hosting
The DomainKeys Identified Mail option is activated by default for all domain names that are hosted in a shared website hosting
account on our cloud web hosting platform, so you will not need to do anything yourself to turn it on. The only condition is that the particular domain should be hosted in a web hosting account on our end using our MX and NS resource records, so that the emails will go through our mail servers. The private cryptographic key will be created on the server and the TXT record, which contains the public key, will be published to the DNS database automatically, so you will not need to do anything manually on your end in order to enable this feature. The DomainKeys Identified Mail email validation system will enable you to send credible emails, so if you are sending offers or a newsletter to customers, for example, your email messages will always reach their target destination, whereas unauthorized 3rd parties won’t be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
If you pick one of the semi-dedicated hosting plans
offered by our company, you’ll be able to use DKIM protection with any domain that you add to your new account without any manual setup, as our top-notch cloud hosting platform will create all the obligatory records automatically, as long as the domain uses our name servers. The aforementioned is needed for a TXT resource record to be created for the domain, since this is how the public key can become available in the global Domain Name System. The private key will also be added automatically to our mail servers, so anytime you send a new email message, it will carry our platform’s e-signature. The number of junk emails keeps increasing every year and very frequently counterfeit email addresses are used, but when you make use of our hosting services, you and your customers or colleagues won’t have to bother about that.
