DKIM, which is short for DomainKeys Identified Mail, is a validation system, which obstructs email headers from being forged and email content from being meddled with. This is done by attaching an e-signature to every email sent from an email address under a specific domain name. The signature is generated based on a private cryptographic key that is available on the outbound 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 forged sender can be spotted by email service providers. This method will heighten your web security considerably and you will know for sure that any message sent from a business ally, a bank, and so on, is a legitimate one. When you send email messages, the recipient will also be sure that you are indeed the one who has sent them. Any mail that turns out to be forged may either be marked as such or may never appear in the receiver’s inbox, depending on how the given provider has chosen to cope with such email messages.

DomainKeys Identified Mail in Website Hosting

The DomainKeys Identified Mail feature is pre-enabled for all domains that are hosted in a website hosting account on our cloud platform, so you will not have to do anything on your end to turn it on. The sole condition is that the particular domain name should be hosted in a hosting account on our end using our NS and MX resource records, so that the e-mail messages will go through our mail servers. The private cryptographic key will be created on the server and the TXT record, which contains the public key, will be published to the Domain Name System automatically, so you will not have to do anything manually on your end in order to activate this functionality. The DKIM email validation system will allow you to send out credible emails, so if you’re sending a newsletter or offers to customers, for example, your email messages will always reach their target viewers, whereas unauthorized 3rd parties will not be able to forge your email addresses.
