DomainKeys Identified Mail (DKIM) is an email validation system used to check that an e-mail has been sent by an authorized individual or email server. An e-signature is added to the email’s header using a private encryption key. When the email is received, a public key that’s available in the global Domain Name System is used to check who exactly sent it and if the content has been altered in any way. The chief job of DomainKeys Identified Mail is to hinder the widespread scam and spam emails, as it makes it impossible to forge an email address. If an email is sent from an email address claiming to belong to your bank, for instance, but the signature does not match, you will either not receive the email at all, or you will receive it with a warning that most likely it’s not legitimate. It depends on email service providers what exactly will happen with an email message which fails the signature test. DomainKeys Identified Mail will also give you an additional security layer when you communicate with your business associates, for example, as they can see for themselves that all the messages that you send are authentic and haven’t been modified in the meantime.

DomainKeys Identified Mail in Hosting

When you purchase any of the hosting that we’re offering, the DomainKeys Identified Mail functionality will be enabled as standard for any domain name that you add to your shared account, so you won’t have to create any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our MX and NS records (so that the emails associated with this domain will be handled by our cloud platform), a private cryptographic key will be issued instantly on our mail servers and a TXT resource record with a public key will be sent to the global DNS system. All addresses created using this domain will be protected by DKIM, so if you send out emails such as regular newsletters, they will reach their target audience and the receivers will know that the messages are legitimate, since the DomainKeys Identified Mail functionality makes it impossible for unsolicited persons to forge your e-mail addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DomainKeys Identified Mail activated by default, so if you pick a semi-dedicated server package and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be created automatically – a private cryptographic key on our mail servers for the e-signature and a TXT resource record carrying the public key for the DNS system. As the DKIM protection is set up for a specific domain name, all addresses created under it will have a signature, so you will not need to worry that the messages that you send out may not reach their destination email address or that somebody may forge any of your addresses and try to scam/spam people. This may be really essential if you use email communication in your business, as your colleagues and/or clients will be able to distinguish real messages from bogus ones.
