DomainKeys Identified Mail, or DKIM, is a method for confirming the authenticity of an email using a digital signature. When DKIM is enabled for a given domain, a public cryptographic key is published to the global Domain Name System and a private one is kept on the email server. If a new email is sent, a signature is issued using the private key and when the message is received, that signature is checked by the incoming email server using the public key. In this way, the receiver can easily distinguish if the email message is genuine or if the sender’s email address has been spoofed. A discrepancy will appear if the content of the email message has been modified in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received email messages are identical and that nothing has been attached or erased. This email authentication system will heighten your email security, as you can confirm the genuineness of the important emails that you get and your associates can do the exact same thing with the emails that you send them. Depending on the particular email provider’s adopted policy, a message that fails the examination may be erased or may enter the receiver’s inbox with a warning.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail feature is enabled by default for all domains that are hosted in a shared hosting account on our cloud servers, so you will not need to do anything on your end to turn it on. The sole requirement is that the given domain name should be hosted in a website hosting account on our platform using our MX and NS resource records, so that the e-mail messages will go through our email servers. The private encryption key will be generated on the server and the TXT record, which contains the public key, will be published to the Domain Name System automatically, so you won’t need to do anything manually on your end in order to activate this feature. The DKIM authentication system will enable you to send trustworthy emails, so if you are sending offers or a newsletter to customers, for instance, your email messages will always reach their target viewers, while unauthorized third parties will not be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

When you pick any of the Linux semi-dedicated hosting offered by our company, you will be able to use DKIM protection with any domain name that you register through your brand-new semi-dedicated account without any manual setup, as our avant-garde cloud hosting platform will set up all the needed records automatically, provided that the domain uses our name servers. The latter is needed for a TXT resource record to be set up for the domain, 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 email servers, so anytime you send a new email message, it will carry our system’s digital signature. The number of spam email messages keeps growing every year and quite often spoofed email addresses are used, but if you make use of our hosting services, you and your customers or associates won’t need to worry about that.
