DomainKeys Identified Mail (DKIM) is an authentication system used to verify that an e-mail message has been sent by an authorized person or email server. A digital signature is added to the email’s header using a private cryptographic key. When the email message is received, a public key that is available in the global Domain Name System is used to confirm who actually sent it and if the content has been edited in some way. The main purpose of DKIM is to avert the widely spread scam and spam 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 doesn’t match, you will either not get the message at all, or you will get it with a warning note that most likely it’s not a genuine one. It depends on mail service providers what exactly will happen with an email message that fails to pass the signature check. DKIM will also supply you with an additional layer of security when you communicate with your business associates, for example, since they can see that all the messages that you send are authentic and haven’t been tampered with in the meantime.
DomainKeys Identified Mail in Shared Web Hosting
In case you host a domain in a shared web hosting
account with us, all the mandatory records for using the DomainKeys Identified Mail option will be set up by default. This will happen as soon as you add the domain in the Control Panel’s Hosted Domains section, on the condition that it also uses our NS records. A private key will be created on our email servers, whereas a public key will be published to the global Domain Name System automatically by using the TXT record. In this way, you will not have to do anything manually and you will be able to take advantage of all the benefits of this validation system – your emails will be delivered to any audience without being denied and nobody will be able to send emails forging your email addresses. The latter is rather important if the nature of your Internet presence suggests sending out regular offers or newsletters via email to prospective and current customers.
DomainKeys Identified Mail in Semi-dedicated Servers
If you opt for one of the semi-dedicated servers
that we offer, you’ll be able to use the DomainKeys Identified Mail option with any domain that you register through your new semi-dedicated hosting account without any manual setup, as our high-tech cloud hosting platform will set up all the compulsory records automatically, provided that the domain uses our name servers. The latter is required for a TXT resource record to be set up for the domain name, since this is how the public cryptographic key can become available in the global DNS database. The private key will also be added automatically to our mail servers, so anytime you send a new message, it will carry our platform’s electronic signature. The number of junk emails keeps increasing every year and quite frequently spoofed addresses are used, but when you make use of our web hosting services, you and your clients or colleagues will not need to bother about that.
