DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an email message has been sent by an authenticated mail server or individual. An electronic signature is added to the header of the email message using a private encryption key. When the email message is received, a public key that is available in the global DNS database is used to validate who exactly sent it and if its content has been modified in any way. The primary job of DomainKeys Identified Mail is to obstruct the widely spread spam and scam emails, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature doesn’t match, you will either not receive the message at all, or you’ll receive it with a warning note that most likely it is not authentic. It depends on email providers what exactly will happen with an email that fails the signature test. DKIM will also give you an extra safety layer when you communicate with your business associates, for example, as they can see for themselves that all the e-mail messages that you send are legitimate and haven’t been tampered with on their way.

DomainKeys Identified Mail in Hosting

The DomainKeys Identified Mail feature is activated by default for all domains that are hosted in a hosting account on our cloud servers, so you will not need to do anything yourself to activate it. The only requirement is that the particular domain should be hosted in an account on our end using our MX and NS records, so that the e-mail messages will go through our email servers. The private cryptographic key will be generated on the server and the TXT record, which contains the public key, will be published to the Domain Name System automatically, so you won’t have to do anything manually on your end in order to enable this option. The DKIM validation system will allow you to send trustworthy email messages, so if you’re sending offers or a newsletter to clients, for instance, your email messages will always reach their target destination, whereas unsolicited 3rd parties will not be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

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