DKIM, which is an abbreviation for DomainKeys Identified Mail, is an authentication system, which stops 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 address under a particular domain name. The signature is created on the basis of a private cryptographic key that is available on the outbound SMTP email server and it can be verified 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 increase your online safety considerably and you’ll know for sure that any e-mail message sent from a business ally, a banking institution, and so on, is genuine. When you send out emails, the recipient will also know for sure that you are indeed the one who has sent them. Any email message that appears to be counterfeit may either be tagged as such or may never reach the receiver’s mailbox, based on how the given provider has chosen to handle such messages.

DomainKeys Identified Mail in Website Hosting

The DomainKeys Identified Mail functionality is enabled by default for all domain names that are hosted in a website hosting account on our cloud platform, so you won’t need to do anything yourself to turn it on. The sole condition is that the particular domain name should be hosted in a website hosting account on our platform using our NS and MX records, so that the emails will go through our mail servers. The private key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global DNS system automatically, so you will not have to do anything manually on your end in order to enable this option. The DKIM email authentication system will allow you to send credible messages, so if you’re sending offers or a newsletter to customers, for example, your email messages will always reach their target destination, whereas unsolicited 3rd parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated hosting plans come with DKIM activated by default, so in case you pick a semi-dedicated hosting plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the authentication system will be set up automatically – a private key on our email servers for the e-signature and a TXT resource record carrying the public key for the Domain Name System. Since the DKIM protection is set up for a specific domain, all e-mail addresses created using it will carry a signature, so you will not need to worry that the emails that you send may not be delivered to their target address or that someone may spoof any of your addresses and try to spam/scam people. This may be rather important when you rely on electronic communication in your business, as your partners and/or customers will be able to distinguish real messages from spoofed ones.
