DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an e-mail message has been sent by an authenticated individual or server. A digital signature is attached to the email’s header using a private cryptographic key. When the email is received, a public key that’s available in the global DNS database is used to validate who actually sent it and if its content has been edited in any way. The essential task of DKIM is to obstruct the widespread scam and spam email messages, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t match, you will either not get the email message at all, or you will get it with a warning notification that most probably it is not an authentic one. It depends on email service providers what exactly will happen with an email message that fails the signature check. DomainKeys Identified Mail will also offer you an added layer of security when you communicate with your business partners, for example, since they can see that all the emails that you exchange are genuine and have not been tampered with on their way.

DomainKeys Identified Mail in Shared Hosting

When you order one of the Linux shared hosting packages that we’re offering, the DomainKeys Identified Mail feature will be enabled by default for any domain that you add to your website hosting account, so you will not have to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS resource records (so that the emails related to this domain name will be handled by our cloud web hosting platform), a private encryption key will be generated momentarily on our email servers and a TXT record with a public key will be sent to the global DNS database. All email addresses created using this domain 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 receivers will be sure that the messages are genuine, since the DomainKeys Identified Mail functionality makes it impossible for unauthorized parties to forge your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting packages come with DKIM enabled by default, so if you select a semi-dedicated hosting plan and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the authentication system will be created automatically – a private key on our mail servers for the digital signature and a TXT record carrying the public key for the DNS system. Since the DKIM protection is set up for a given domain, all email addresses created using it will have a signature, so you won’t have to worry that the messages that you send out may not be delivered to their destination email address or that somebody may forge any of your addresses and try to spam/scam people. This may be quite important when you rely on e-communication in your business, since your associates and/or customers will be able to distinguish genuine email messages from false ones.
