DomainKeys Identified Mail (DKIM) is an email validation system used to certify that an email message has been sent by an authenticated individual or mail server. A digital signature is added to the header of the message using a private encryption key. When the message is received, a public key that is available in the global Domain Name System is used to confirm who exactly sent it and if the content has been modified in some way. The prime job of DKIM is to obstruct the widespread scam and spam email messages, as it makes it impossible to forge an email address. If an email message is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t correspond, you will either not receive the message at all, or you will receive it with a warning note that most likely it is not a genuine one. It depends on mail service providers what exactly will happen with an email which fails to pass the signature examination. DomainKeys Identified Mail will also supply you with an added security layer when you communicate with your business partners, for instance, as they can see that all the e-mail messages that you send are authentic and haven’t been manipulated in the meantime.
DomainKeys Identified Mail in Shared Hosting
If you host a domain in a shared hosting account from our company, all the needed records for using the DomainKeys Identified Mail feature will be created by default. This will happen as soon as you add the domain name in the Control Panel’s Hosted Domains section, as long as it also uses our NS resource records. A private encryption key will be generated on our mail servers, whereas a public key will be published to the DNS database automatically using the TXT record. Thus, you won’t have to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your email messages will be delivered to any destination without being discarded and nobody will be able to send email messages forging your email addresses. The latter is truly important in case the type of your online presence involves sending periodic offers or newsletters via email to prospective and current clients.
DomainKeys Identified Mail in Semi-dedicated Hosting
When you select any of the Linux semi-dedicated hosting that we offer, you’ll be able to use the DomainKeys Identified Mail protection service with any domain that you add to your brand new semi-dedicated account without any manual setup, as our leading-edge cloud web hosting platform will set up all the compulsory records automatically, provided that the domain name 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 encryption 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 out a new email message, it will carry our system’s electronic signature. The number of spam emails keeps increasing each year and quite frequently false email addresses are used, but if you use our web hosting services, you and your customers or partners will not have to bother about that.
