DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email using an electronic signature. When DomainKeys Identified Mail is activated for a certain domain name, a public key is published to the global Domain Name System and a private one is kept on the mail server. When a new email message is sent, a signature is issued using the private key and when the message is delivered, the signature is checked by the POP3/IMAP server using the public key. In this way, the recipient can easily distinguish if the email message is genuine or if the sender’s email address has been forged. A mismatch will appear if the content of the email message has been altered in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received emails are identical and that nothing has been attached or erased. This email authentication system will increase your email security, as you can validate the authenticity of the important email messages that you get and your colleagues can do the same with the emails that you send them. Based on the particular email service provider’s adopted policy, an email message that fails to pass the check may be removed or may enter the receiver’s inbox with a warning notification.
DomainKeys Identified Mail in Shared Website Hosting
If you host a domain name in a shared website hosting account with our company, all the mandatory records for using the DomainKeys Identified Mail feature will be set up by default. This will happen the moment you add the domain name in the Control Panel’s Hosted Domains section, provided that it also uses our NS resource records. A private key will be generated on our email servers, while a public key will be published to the global DNS database automatically using the TXT record. Thus, you won’t have to do anything manually and you will be able to take advantage of all the benefits of this authentication system – your email messages will be sent to any target destination without being rejected and no one will be able to send out email messages forging your email addresses. The latter is quite important if the nature of your Internet presence suggests sending regular offers or newsletters via email to potential and existing clients.
DomainKeys Identified Mail in Semi-dedicated Hosting
When you opt for one of the Linux semi-dedicated hosting packages offered by our company, you’ll be able to use the DKIM protection service with any domain that you register through your brand-new account without any manual intervention, as our outstanding cloud web hosting platform will set up all the obligatory records automatically, on the condition that the domain name uses our name servers. The latter is required for a TXT resource record to be set up for the domain name, as this is how the public cryptographic 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 a new email message, it will carry our system’s e-signature. The number of unsolicited bulk messages keeps increasing each year and rather frequently spoofed email addresses are used, but if you make use of our web hosting services, you and your clients or partners won’t need to worry about that.
