DomainKeys Identified Mail (DKIM) is an authentication system used to check that an email message has been sent by an authenticated server or person. A digital signature is added to the email message’s header using a private key. When the message is received, a public key that is available in the global DNS database is used to verify who actually sent it and if its content has been modified in some way. The fundamental task of DKIM is to hamper the widely spread scam and spam messages, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for example, but the signature does not match, you will either not get the email message at all, or you will receive it with a warning notification that most probably it’s not a genuine one. It depends on email providers what exactly will happen with an email message which fails the signature examination. DKIM will also offer you an extra layer of protection when you communicate with your business associates, for instance, as they can see that all the emails that you send are legitimate and haven’t been tampered with on their way.

DomainKeys Identified Mail in Cloud Hosting

If you purchase any of the Linux cloud hosting that we are offering, the DomainKeys Identified Mail feature will be enabled as standard for any domain name that you add to your shared web hosting account, so you will not need to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX resource records (so that the email messages related to this domain name will be handled by our cloud platform), a private key will be generated instantly on our mail servers and a TXT resource record with a public key will be sent to the DNS system. All addresses created with this domain name will be protected by DKIM, so if you send email messages such as regular newsletters, they will reach their target audience and the recipients will be sure that the messages are authentic, because the DomainKeys Identified Mail functionality makes it impossible for unsolicited individuals to forge your addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so if you choose a semi-dedicated server plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the email validation system will be created automatically – a private encryption key on our email servers for the digital signature and a TXT record carrying the public key for the DNS database. Since the DKIM protection is set up for a particular domain name, all e-mail addresses created with it will carry a signature, so you will not need to worry that the emails that you send may not be delivered to their destination email address or that someone may fake any of your email addresses and try to scam/spam people. This may be very essential when you rely on e-communication in your business, since your colleagues and/or customers will be able to distinguish authentic email messages from counterfeit ones.
