DKIM, which is an acronym for DomainKeys Identified Mail, is an email authentication system, which blocks email addresses from being spoofed and email content from being modified. This is achieved by attaching an e-signature to every email sent from an address under a specific domain. The signature is generated based on a private cryptographic key that is available on the outgoing SMTP email 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 technology will boost your online security substantially and you’ll be sure that any e-mail sent from a business collaborator, a bank, and so on, is legitimate. When you send out 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 labeled as such or may never reach the recipient’s mailbox, depending on how the particular provider has chosen to cope with such messages.

DomainKeys Identified Mail in Shared Hosting

If you order one of the Linux shared hosting that we offer, the DomainKeys Identified Mail feature will be activated by default for any domain that you add to your shared website hosting account, so you will not have to set up any records or to activate anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX resource records (so that the email messages associated with this domain name will be handled by our cloud platform), a private cryptographic key will be created straight away on our mail servers and a TXT record with a public key will be sent to the DNS system. All email addresses set up using this domain will be protected by DomainKeys Identified Mail, so if you send emails such as periodic newsletters, they will reach their target audience and the receivers will know that the messages are legitimate, because the DomainKeys Identified Mail functionality makes it impossible for unsolicited parties to forge your e-mail addresses.
