DKIM, which is short for DomainKeys Identified Mail, is an email authentication system, which obstructs email addresses from being forged and email content from being modified. This is done by attaching an e-signature to each message sent from an address under a particular domain name. The signature is generated on the basis of a private cryptographic key that is available on the outbound SMTP email server and it can be validated using a public key, which is available in the global Domain Name System. Thus, any email message with changed content or a forged sender can be recognized by mail service providers. This approach will strengthen your web security dramatically and you will be sure that any e-mail message sent from a business partner, a banking institution, etc., is a genuine one. When you send messages, the receiver will also know for sure that you are indeed the one who has sent them. Any email that turns out to be phony may either be labeled as such or may never appear in the recipient’s mailbox, depending on how the particular provider has chosen to treat such emails.

DomainKeys Identified Mail in Hosting

The DomainKeys Identified Mail feature is enabled by default for all domains that are hosted in a hosting account on our cloud servers, so you won’t have to do anything yourself to turn it on. The only requirement is that the given domain name should be hosted in a hosting account on our end using our MX and NS records, so that the emails 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 DNS system automatically, so you won’t have to do anything manually on your end in order to enable this functionality. The DKIM email authentication system will permit you to send trustable emails, so if you’re sending a newsletter or offers to customers, for example, your emails will always reach their target viewers, while unauthorized third parties won’t be able to spoof your email addresses.
