DKIM, which is an acronym for DomainKeys Identified Mail, is an email validation system, which prevents email headers from being spoofed and email content from being tampered with. This is achieved by attaching a digital signature to each email message sent from an address under a particular domain. The signature is issued on the basis of a private cryptographic key that is available on the SMTP mail server and it can be verified by using a public key, which is available in the global DNS database. In this way, any email with modified content or a spoofed sender can be identified by mail service providers. This approach will increase your web safety markedly and you’ll be sure that any e-mail message sent from a business collaborator, a banking institution, etc., is genuine. When you send out emails, the receiver will also be sure that you are indeed the one who has sent them. Any email message that turns out to be phony may either be flagged as such or may never show up in the recipient’s inbox, depending on how the given provider has decided to treat such messages.

DomainKeys Identified Mail in Shared Hosting

When you buy any of the Linux shared hosting that we are offering, the DomainKeys Identified Mail option will be activated as standard for any domain name that you add to your shared website hosting account, so you won’t have to set up any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX records (so that the email messages related to this domain name will be handled by our cloud hosting platform), a private key will be issued instantly on our email servers and a TXT resource record with a public key will be sent to the Domain Name System. All addresses created using this domain name will be protected by DomainKeys Identified Mail, so if you send email messages such as regular newsletters, they will reach their target audience and the recipients will know that the messages are authentic, since the DKIM functionality makes it impossible for unauthorized persons to spoof your email addresses.
