DKIM, which stands for DomainKeys Identified Mail, is an email authentication system, which blocks email headers from being spoofed and email content from being modified. This is achieved by adding a digital signature to each and every message sent from an email address under a certain domain. The signature is issued based on a private cryptographic key that is available on the outbound mail server and it can be verified by using a public key, which is available in the global Domain Name System. Thus, any message with edited content or a forged sender can be identified by mail service providers. This approach will enhance your online security dramatically and you’ll be sure that any e-mail message sent from a business partner, a bank, etc., is a legitimate one. When you send out email messages, the receiver will also be sure that you are indeed the one who has sent them. Any mail that appears to be counterfeit may either be tagged as such or may never be delivered to the recipient’s mailbox, depending on how the particular provider has chosen to handle such messages.

DomainKeys Identified Mail in Shared Hosting

In case you host a domain name in a shared hosting account from us, all the obligatory records for using the DomainKeys Identified Mail functionality will be set up by default. This will happen the moment you add the domain 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 mail servers, whereas a public key will be sent to the DNS database automatically using the TXT resource record. Thus, you will not have to do anything manually and you will be able to take full advantage of all the benefits of this email validation system – your messages will be sent to any target audience without being discarded and no one will be able to send email messages forging your addresses. The latter is really important in case the essence of your online presence involves sending regular newsletters or offers via email to prospective and existing clients.
