DomainKeys Identified Mail (DKIM) is an authentication system used to prove that an email message has been sent by an authenticated person or server. An electronic signature is attached to the header of the email using a private encryption key. When the email is received, a public key that is available in the global Domain Name System is used to check who actually sent it and if the content has been edited in any way. The prime task of DKIM is to hamper the widely spread spam and scam messages, as it makes it impossible to forge an email address. If an email is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not match, you will either not receive the message at all, or you’ll get it with a warning notification that most probably it’s not genuine. It depends on mail service providers what exactly will happen with an email which fails the signature check. DKIM will also offer you an added layer of protection when you communicate with your business associates, for instance, since they can see that all the e-mail messages that you exchange are genuine and haven’t been meddled with on their way.
DomainKeys Identified Mail in Shared Website Hosting
The DomainKeys Identified Mail functionality is pre-enabled for all domains that are hosted in a shared website hosting account on our cloud web hosting platform, so you will not have to do anything yourself to activate it. The only condition is that the particular domain name should be hosted in a hosting account on our end using our MX and NS records, so that the email messages will go through our email 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 Domain Name System automatically, so you will not need to do anything manually on your end in order to enable this feature. The DomainKeys Identified Mail authentication system will permit you to send trustable e-mail messages, so if you are sending offers or a newsletter to clients, for example, your emails will always reach their target destination, whereas unauthorized 3rd parties will not be able to forge your email addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
When you pick one of the Linux semi-dedicated plans offered by us, you’ll be able to use the DKIM feature with any domain that you register through your brand new account without any manual setup, as our top-notch cloud web hosting platform will set up all the needed records automatically, on the condition that the domain uses our name servers. The aforementioned is required for a TXT record to be set up for the domain name, as this is how the public cryptographic key can become available in the global Domain Name System. The private key will also be added automatically to our email servers, so whenever you send a new email, it will have our system’s electronic signature. The number of unsolicited bulk messages keeps rising each year and rather often forged addresses are used, but if you use our web hosting services, you and your clients or colleagues will not have to worry about that.
