DomainKeys Identified Mail (DKIM) is a validation system used to prove that an email has been sent by an authenticated server or individual. An e-signature is added to the header of the email by using a private cryptographic key. When the email is received, a public key that is available in the global DNS database is used to check who actually sent it and if the content has been altered in any way. The main job of DKIM is to impede 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 or financial institution, for instance, but the signature does not correspond, you will either not get the message at all, or you will receive it with a warning note that most likely it’s not an authentic one. It depends on mail service providers what exactly will happen with an email that fails the signature check. DKIM will also give you an added layer of protection when you communicate with your business allies, for instance, since they can see that all the e-mails that you send are genuine and haven’t been meddled with on their way.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail feature is activated by default for all domains that are hosted in a web hosting account on our cloud hosting platform, so you will not need to do anything yourself to activate it. The only condition is that the particular domain should be hosted in a hosting account on our end using our MX and NS records, so that the emails will go through our email servers. The private key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global Domain Name System automatically, so you will not need to do anything manually on your end in order to enable this functionality. The DomainKeys Identified Mail authentication system will allow you to send trustworthy emails, so if you’re sending offers or a newsletter to clients, for example, your email messages will always reach their target destination, while unsolicited third parties won’t be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our semi-dedicated hosting packages come with DomainKeys Identified Mail activated by default, so in case you choose a semi-dedicated package and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the email authentication system will be created automatically – a private key on our email servers for the digital signature and a TXT resource record carrying the public key for the global DNS database. Since the protection is set up for a specific domain, all addresses created using it will have a signature, so you will not have to worry that the email messages that you send out may not be delivered to their target address or that somebody may fake any of your addresses and attempt to scam/spam people. This may be quite essential in case you use email communication in your business, as your associates and/or customers will be able to distinguish genuine emails from forged ones.
