DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an email message has been sent by an authorized server or person. A digital signature is added to the header of the email message using a private cryptographic key. When the email message is received, a public key that’s available in the global Domain Name System is used to check who actually sent it and whether its content has been modified in some way. The main purpose of DKIM is to block the widespread scam and spam messages, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank, for instance, but the signature doesn’t correspond, you will either not get the email at all, or you’ll receive it with a warning note that most likely it is not authentic. It depends on email providers what exactly will happen with an email message that fails the signature test. DomainKeys Identified Mail will also give you an extra safety layer when you communicate with your business allies, for example, since they can see that all the e-mails that you send are legitimate and haven’t been tampered with on their way.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail option is activated by default for all domains that are hosted in a cloud hosting account on our cloud website hosting platform, so you will not have to do anything on your end to activate it. The only condition is that the given domain should be hosted in a web hosting account on our platform using our MX and NS resource records, so that the email messages will go through our mail servers. The private encryption key will be generated on the server and the TXT resource 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 functionality. The DomainKeys Identified Mail email validation system will permit you to send credible e-mail messages, so if you’re sending offers or a newsletter to customers, for example, your email messages will always reach their target audience, while unauthorized 3rd parties won’t be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

When you pick one of the Linux semi-dedicated hosting that we offer, you’ll be able to use DKIM protection with any domain that you register through your brand new semi-dedicated hosting account without any manual intervention, as our leading-edge cloud platform will set up all the obligatory records automatically, as long as the domain uses our name servers. The latter is required for a TXT resource record to be set up for the domain, 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 mail servers, so anytime you send out a new email, it will carry our system’s electronic signature. The number of unsolicited bulk messages continues to grow every year and quite frequently phony addresses are used, but when you make use of our hosting services, you and your customers or colleagues won’t need to bother about that.
