DomainKeys Identified Mail (DKIM) is an email authentication system used to prove that an e-mail has been sent by an authenticated individual or email server. An electronic signature is added to the message’s header using a private key. When the message is received, a public key that’s available in the global DNS database is used to confirm who exactly sent it and whether the content has been edited in some way. The primary task of DKIM is to hamper the widely spread spam and scam messages, as it makes it impossible to forge an email address. If an email is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not receive the email message at all, or you’ll get it with a warning notification that most probably it is not a legitimate one. It depends on email service providers what exactly will happen with an email that fails to pass the signature check. DomainKeys Identified Mail will also supply you with an additional layer of security when you communicate with your business partners, for example, since they can see that all the emails that you send are genuine and haven’t been modified on their way.

DomainKeys Identified Mail in Shared Hosting

If you host a domain name in a shared hosting account with us, all the required records for using the DomainKeys Identified Mail feature will be created by default. This will happen the moment you add the domain name in the Control Panel’s Hosted Domains section, provided that it also uses our NS resource records. A private key will be created on our mail servers, while a public key will be added to the Domain Name System automatically by using the TXT record. Thus, you will not 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 disallowed and no one will be able to send out messages faking your addresses. The latter is really important if the type of your online presence involves sending out periodic newsletters or offers via email to prospective and current clients.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail enabled by default, so in case you select this type of hosting and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the validation system will be created automatically – a private 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 certain domain name, all email addresses created using it will carry a signature, so you will not have to worry that the emails that you send may not reach their target address or that someone may spoof any of your email addresses and try to scam/spam people. This may be really important in case you rely on electronic communication in your business, since your partners and/or clients will be able to distinguish real email messages from bogus ones.
