DomainKeys Identified Mail, or DKIM, is a method for checking the genuineness of an email by using a digital signature. When DKIM is activated for a certain domain name, a public encryption key is published to the global DNS database and a private one is stored on the email server. If a new message is sent, a signature is issued using the private key and when the email message is received, that signature is ‘scanned’ by the POP3/IMAP mail server using the public key. Thus, the receiver can easily tell if the email message is genuine or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email message has been changed in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or erased. This authentication system will strengthen your email safety, as you can confirm the authenticity of the important email messages that you receive and your colleagues can do the same with the email messages that you send them. Depending on the particular email provider’s adopted policy, an email that fails to pass the examination may be erased or may be delivered to the recipient’s inbox with a warning symbol.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail option is pre-activated for all domain names that are hosted in a shared hosting account on our cloud hosting platform, so you won’t need to do anything on your end to enable it. The sole requirement is that the particular domain name should be hosted in an account on our end using our MX and NS records, so that the e-mail 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 DNS system automatically, so you won’t need to do anything manually on your end in order to enable this option. The DomainKeys Identified Mail email validation system will permit you to send trustable email messages, so if you are sending offers or a newsletter to customers, for example, your emails will always reach their target audience, whereas unauthorized third parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

If you select one of the Linux semi-dedicated packages that we offer, you will be able to use the DomainKeys Identified Mail feature with any domain that you add to your new account without any manual setup, as our innovative cloud platform will create all the required records automatically, as long as the domain uses our name servers. The latter is needed for a TXT resource record to be created for the domain name, as this is how the public key can become available in the global DNS system. The private key will also be added automatically to our mail servers, so anytime you send out a new email, it will include our platform’s e-signature. The number of spam messages continues to increase every year and very often counterfeit email addresses are used, but if you use our web hosting services, you and your customers or colleagues will not need to worry about that.
