DKIM, which is an acronym for DomainKeys Identified Mail, is an email validation system, which blocks email addresses from being forged and email content from being modified. This is done by adding a digital signature to each and every email message sent from an email address under a certain domain. The signature is generated on the basis of a private encryption key that is available on the outgoing SMTP mail server and it can be verified by using a public key, which is available in the global DNS database. Thus, any email message with altered content or a spoofed sender can be recognized by email providers. This approach will boost your web safety immensely and you will be sure that any e-mail sent from a business partner, a banking institution, etc., is a legitimate one. When you send out messages, the recipient will also be sure that you are indeed the one who has sent them. Any email that appears to be bogus may either be tagged as such or may never be delivered to the receiver’s inbox, based on how the particular provider has decided to handle such email messages.

DomainKeys Identified Mail in Shared Website Hosting

If you host a domain in a shared website hosting account from our company, all the required records for using the DomainKeys Identified Mail feature will be created by default. This will happen once you add the domain name in the Control Panel’s Hosted Domains section, as long as the domain also uses our NS records. A private cryptographic key will be generated on our email servers, while a public key will be sent to the global DNS system automatically using the TXT resource record. In this way, you will not need to do anything manually and you’ll be able to take full advantage of all the benefits of this authentication system – your email messages will be sent to any target audience 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 prospective and current clients.
