DomainKeys Identified Mail (DKIM) is a validation system used to confirm that an email has been sent by an authorized individual or email server. An e-signature is added to the email’s header using a private cryptographic key. When the message is received, a public key that is available in the global Domain Name System is used to verify who exactly sent it and whether its content has been altered in any way. The main task of DomainKeys Identified Mail is to impede the widespread spam and scam email messages, as it makes it impossible to fake an email address. If an email 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 message at all, or you’ll receive it with a warning notice that most likely it is not authentic. It depends on mail service providers what exactly will happen with an email message which fails the signature check. DomainKeys Identified Mail will also offer you an added layer of security when you communicate with your business associates, for instance, as they can see for themselves that all the messages that you exchange are legitimate and have not been tampered with in the meantime.

DomainKeys Identified Mail in Website Hosting

When you purchase one of the website hosting that we are offering, the DomainKeys Identified Mail option will be enabled by default for any domain name that you register under your shared 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 in-house developed Hepsia Control Panel using our MX and NS resource records (so that the email messages related to this domain will be handled by our cloud hosting platform), a private key will be generated instantly on our email servers and a TXT record with a public key will be sent to the DNS system. All addresses set up using this domain will be protected by DomainKeys Identified Mail, so if you send out email messages such as periodic newsletters, they will reach their target audience and the receivers will be sure that they are authentic, since the DKIM feature makes it impossible for unsolicited persons to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so if you opt for a semi-dedicated hosting plan and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private cryptographic key on our mail servers for the digital signature and a TXT resource record carrying the public key for the DNS database. Since the DKIM protection is set up for a certain domain name, all e-mail addresses created under it will have a signature, so you won’t need to worry that the messages that you send out may not be delivered to their destination address or that somebody may spoof any of your addresses and try to scam/spam people. This may be very important if you rely on email communication in your business, since your associates and/or clients will be able to distinguish legitimate messages from false ones.
