DKIM, which is an abbreviation for DomainKeys Identified Mail, is an email authentication system, which impedes email headers from being forged and email content from being manipulated. This is done by attaching an electronic signature to each email message sent from an address under a given domain. The signature is issued based on a private cryptographic key that’s available on the outgoing SMTP server and it can be validated by using a public key, which is available in the global DNS database. In this way, any email message with modified content or a forged sender can be recognized by mail service providers. This technology will boost your web safety noticeably and you’ll be sure that any email message sent from a business collaborator, a bank, and so on, 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 counterfeit may either be marked as such or may never be delivered to the recipient’s mailbox, depending on how the particular provider has decided to treat such email messages.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail feature is enabled by default for all domain names that are hosted in a shared hosting account on our cloud hosting platform, so you won’t have to do anything yourself to activate it. The only requirement is that the given domain name should be hosted in a hosting account on our end using our NS and MX resource records, so that the emails will go through our email servers. The private key will be created on the server and the TXT resource record, which includes 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 option. The DKIM validation system will allow you to send out trustable emails, so if you’re sending offers or a newsletter to clients, for example, your email messages will always reach their target audience, whereas unauthorized third parties will not be able to spoof your email addresses.
