DomainKeys Identified Mail (DKIM) is an authentication system used to confirm that an e-mail has been sent by an authorized individual or mail server. A digital signature is attached to the header of the email message by using a private key. When the email is received, a public key that is available in the global Domain Name System is used to validate who actually sent it and whether its content has been modified in any way. The principal purpose of DKIM is to block the widespread scam and spam emails, as it makes it impossible to forge an email address. If an email message is sent from an email 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 at all, or you will receive it with a warning alert that most probably it is not authentic. It depends on email service providers what exactly will happen with an email message that fails to pass the signature examination. DomainKeys Identified Mail will also give you an added protection layer when you communicate with your business associates, for instance, as they can see that all the e-mails that you exchange are legitimate and haven’t been tampered with on their way.
DomainKeys Identified Mail in Shared Hosting
In case you host a domain name in a shared hosting account from us, all the obligatory records for using the DomainKeys Identified Mail feature will be added by default. This will happen the moment you add the domain name in the Hosted Domains section of the Hepsia Control Panel, provided that it also uses our NS resource records. A private key will be generated on our email servers, whereas a public key will be sent to the DNS system automatically by using the TXT record. In this way, you won’t need to do anything manually and you’ll be able to take full advantage of all the benefits of this validation system – your emails will reach any target audience without being rejected and no one will be able to send out email messages faking your addresses. The latter is rather important if the essence of your web presence involves sending regular offers or newsletters via email to potential and current customers.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers come with DKIM enabled by default, so if you pick this type of hosting and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private cryptographic key on our email servers for the e-signature and a TXT resource record carrying the public key for the global DNS system. Since the protection is set up for a specific domain name, all addresses created using 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 target address or that someone may forge any of your email addresses and try to spam/scam people. This may be quite important if you use email communication in your business, since your partners and/or clients will be able to distinguish genuine emails from counterfeit ones.
